How Bug Spray Works

Insecticides: The Big Guns

Have you ever wondered why there are so many different types of bug sprays for the pests in and around our homes — one for wasps and hornets, one for ants and roaches, and still another for fleas and ticks? As it turns out, they contain very similar insecticides, although their specific ingredients and formulations differ depending on how and where the sprays will be used.

Most household bug sprays contain one or more insecticides in thepyrethroidfamily. Pyrethroids are synthetic chemicals designed to mimic the natural oils found in chrysanthemum flowers [source: National Pesticide Information Center]. They affect an insect’s central and peripheral nervous systems on contact, causing tremors, paralysis and a quick death [sources: EPA, NPIC]. Pyrethroids are effective against all sorts of insects, including beneficial bugs like bees and butterflies. They’re also highly toxic to fish.

Pyrethroids such aspermethrin,prallethrinandcypermethrinare the active ingredients in many wasp and hornet sprays. If you’ve ever had to deal with a nest in your yard, you know that it’s best to spray in the evening, when these insects are less active. This is partly so they won’t dive-bomb your head as you attempt to wipe out their home and family, but it’s also for efficiency, since the spray is likely to instantly terminate any wasps that are in the nest.

Pyrethroids are also found in sprays targeting ants, roaches, silverfish and other crawling critters. Since it’s not always easy to find the source of an ant or roach invasion, these sprays need to work over an extended time to effectively kill insects outside their nests. For this reason, ant and roach sprays usually containpiperonyl butoxide, an additive that prevents the insecticide ingredients from degrading before they can work [source: NP IC]. These sprays are applied along walls, doorways and insect trails, and the bugs are killed when they ingest or crawl over the residue.

Household flea and tick sprays use pyrethroids to kill adult fleas and ticks, piperonyl butoxide to extend the life of the insecticide ingredients, and a growth inhibitor likepyriproxifento prevent new eggs and larvae from developing [sources: Doctors Foster and Smith, NP IC].

Commercial farmers and backyard gardeners have long relied on a class of insecticides known asneonicotinoidsfor their effectiveness against aphids, beetles and other plant-eating pests. Unfortunately, these neurotoxic liquids and sprays have recently been linked with colony collapse disorder and the decline in the population of honeybees and other pollinators. To help protect bees, check the labels at your local garden center: Products containing neonicotinoids are now required to have a "bee advisory box" on the label [sources: EPA, Texas A&M AgriLife Extension].

How long does it take for commercial sprays to kill bedbugs?

This is a pretty vague question, so I’ll give the best estimates that I can. First, sprays are broken down into two categories: contact sprays kill right away and then evaporate, while residual sprays work more slowly but last a long time. The actual time it takes to kill bed bugs will depend on which type of spray you’re using, as well as on the active ingredients in that spray.

Most contact sprays will kill bed bugs in just seconds. This is assuming that the bug isn’t from a strain that is resistant to the active ingredient that your spray uses. This is a growing problem, so make sure that you’re using professional-strength chemicals with the latest formulas. Avoid grocery store brands at all costs; these are often using outdated formulas.

Residual sprays won’t kill bed bugs immediately, as they’re meant to be laid down in a perimeter and kill bed bugs that pass through the area over a long period of time. Depending on the individual spray, and the conditions of where it was used, a residual insecticide could be effective for anywhere from two weeks to over a year. The time from exposure to death will also vary – some sprays can kill exposed bed bugs in under a minute, while others take several minutes to work.

Bed Bug Insecticides

– Sprays & dusts to combat bed bugs –

Summary: New insecticides are now available that can be used to eliminatebed bugs(all stages) and their eggs that may have been missed during the cleaning of bedding and furniture.

Using bed bug sprays and dust insecticides

The most important part of any bed bug treatment is to thoroughly clean places where bed bugs hide and lay their eggs. These areas includemattress seams and folds,cracks and crevices in bedroom furniture,baseboard molding, and other places near beds where bed bugs might hide (see Bed Bugs for additional information). Cleaning can be done with an ordinary vacuum cleaner and mild upholstery cleaner, butsteam cleanersmay be the most effective.

Once hiding places are as clean as possible you can apply aresidual insecticideto control any bed bugs and eggs that you might have missed with cleaning alone. This application is tricky, however, because products applied to bedding or bedside furniture have the potential to contact anyone who sleeps in the bed. For this reason the material must be safe and used strictly in accordance with the label instructions.

Bed bug(4th instar larva, unfed) – about 1/5". After feeding bed bugs become less flattened, more rounded.

Insecticidal dusts (see below) should be used to treat baseboard moldings and bedroom furniture. Dusts are easy to apply to small cracks and openings without danger of over-application and spillage. Dusts also have longer residual activity than most other types of insecticides.

Are bed bug sprays really necessary?

Surfaces like mattresses can be treated with a residual spray insecticide but only use products that are specifically labeled for this use (check package instructions).

Residual spray insecticides are not absolutely necessary if all surfaces are thoroughly cleaned. However, it is easy to miss a few areas where bed bugs might be hiding, or a few eggs that are tucked inside the fold of a mattress. This is where a residual insecticide comes in, to eliminate the last few survivors of the cleaning process.

Apply avery light sprayto mattress seams and folds, the undersides of bedside furniture and the bed frame. Do not saturate, a light spray is all that is necessary. Bed bug sprays should NOT be substituted for thorough cleaning of mattresses and treatment of cracks and crevices with a dust insecticide.

Bed bug sprays, dust insecticides & cleaners

To properly treat a bed bug infestation you’ll needfabric cleaner or steam cleaner,a dust-type insecticide,a bulb duster, anda residual insecticide spray. There are kits available as well as individual products. Almost any fabric/upholstery cleaner can be used as long as you don’t get mattress fabric too wet. Steam cleaners can be used as well and will be more efficient for large jobs. The dust insecticide is usually a natural silica or pyrethrum insecticide, both work well but the silica has longer residual activity. For the residual spray insecticide I prefer the new botanical insecticides. I would suggest starting out with a kit such as one of these, then replace individual components as necessary.

Bed Bug Control In Homes, Dorm Rooms, Motels/Hostels

Using the following steps you should be able to easily clear, and prevent, most bed bug infestations so long as you catch the infestation at an early stage.

  • Launder bedding as normal.
  • Treat cracks and crevices where bed bugs hide in rooms and around beds with a dust insecticide. So called "crack and crevice" treatments should include baseboards and furniture, and other small, protected places where bed bugs can hide during the day. Dusts should be applied with a duster that allows you to puff the insecticide into tight places.
  • Clean soiled mattress fabric with upholstery cleaner or steam.
  • Apply an aerosol spray or wettable powder insecticide to mattress surfaces and seams, follow label instructions for approved uses.

This spray is designed to kill bed bugs as well as their eggs. It works to eliminate the whole population, helping you keep your business or home free of these unwelcome pests. The broad spectrum of activity assures a complete elimination of the bugs and hinders re-infestation.

How Does the Product Work?

Raid bed bug spray can be used as a spot treatment or surface spray. You can apply the product over a large area as a surface spray. You can also use it to treat tight spots such as cracks and crevices by lifting up its yellow precision wand.

Its active ingredients – cypermethrin and imiprothrin – kill bed bugs as well as their eggs on contact. Raid Max is effective against bed bugs and fleas in all their stages of development. It kills them through dermal contact and digestion. Once absorbed, the product begins a series of activities that render the bed bugs and the fleas helpless and eventually leads to death.

The events that lead to the bug’s death include:

  • Immediately after the absorption, the product paralyzes the insect’s nervous system which leads to a powerful knockdown effect. The interference with the Central Nervous System (CNS) makes the insects immobile, and you will observe them struggling to move after you spray your house with the pesticide. The effect of Raid Max on the CNS is irreversible which guarantees elimination certainty once the insects come into contact with the product. Flies and bed bugs are highly susceptible to the product before dawn.
  • Raid Max Bed Bug and Flea Killer is unique due to its ability to be absorbed both through the cuticle and direct oral intake. The diverse absorption mechanism increases the chances of absorption and consequently elimination of the bugs from your house. Once the bugs ingest the product, it interferes with the normal functioning of the digestive system. The interference hinders the absorption of nutrients which results in lethargy and death. The effects on the CNS and those on the digestive system creates a synergy that ensures total elimination of the bugs within the first hour of application.
  • The product is made from pyrethrins which have high activity against bed bugs and fleas. It has a quick onset of action since it paralyzes the insects in a brief time after the application. Raid Max also interferes with the synthesis of essential enzymes and hormones which impairs the normal functioning of the insects’ physiological system. It is packaged conveniently in an aerosol to ensure that you reach the cracks and crevices where these insects hide as well as use the required pressure when spraying.

Other ingredients that make up the product include:

  • Isopropanol: This helps the product spread over a surface.
  • Ammonium Benzoate: It inhibits corrosion of the container to keep the contents fresh.
  • Isobutane: This propellant helps in dispensing the product from the container.
  • Fragrance: It adds scent to the spray.
  • Propane: This propellant also assists in dispensing the product from the container.
  • Sorbitan Oleate: This helps in breaking down dirt and other deposits.
  • Petroleum Distillate: It promotes even distribution of the ingredients.
  • Water: This is the product’s liquid base.

How Should You Use It?

If you’re concerned about the spray staining or discoloring your items, test it by spraying on an inconspicuous place. Evaluate the area after it dries.

Before you apply this product, make sure you cover or remove drinking water. Cover fish aquariums and remove pets.

Follow these steps when spraying an area:

  1. Shake the container well.
  2. Hold it upright with its nozzle pointing away from you.
  3. Stand at a distance of 8-10 inches from the area to be sprayed.
  4. Depress the valve and spray every square foot for 5 seconds (13 seconds for bedbug eggs) or until the area is damp. When spraying, try to directly apply the product on as many bed bugs as you can. However, take care not to wet the area to the point there’s runoff or dripping.
  5. Vacate a room after treating it. Don’t allow any pet or person to enter treated areas until the spray has dried. Ventilate the areas before you reoccupy them. You should also use or replace your bedding only after allowing the sprayed surfaces and articles to dry completely.

Be sure to wash your hands thoroughly after you’ve finished using the spray. You shouldn’t use the spray in the same area more than once a day.

Where to Use It?

The method used in the application of Raid Max determines the bedbugs and fleas elimination efficiency. It is essential that you ensure a proper application of the product to benefit maximally from its use.

You should always read and understand the manufacturer’s instructions after which you should follow them to the letter. This improves the elimination chances as well as assures safety during the application. The product is ideal for use both indoors and outdoors.

Indoor Use. The product is primarily used inside the house where the fleas and the bed bugs have infested. As a surface spray, you can apply the spray to:

  • box springs,
  • mattresses,
  • carpets,
  • floors,
  • furniture,
  • walls,
  • garments,
  • rugs,
  • luggage,
  • drapes, and
  • closets.

Most Effective Areas to Apply Kills Bedbugs Products

As a spot treatment, you can apply it to:

  • floorboards,
  • baseboards,
  • cracks,
  • crevices,
  • wall hangings,
  • bed frames,
  • door frames,
  • window frames, and
  • headboards.

This use, however, has some risks and you should be cautious.

Directions for the use of the product is as outlined below:

  • Raid Max is applied on non-porous surfaces. It eliminates the bed bugs and the fleas on these surfaces as well as provides a barrier that prevents re-infestation for up to 12 months. When using the product indoors, you should ensure that all the food is stored in sealed containers. Identify the infested areas and spray the product carefully. You should also spray in all the entry and exit points to form a barrier.
  • You should close all the windows and the doors to achieve the desired concentration of the product inside the room. Before the application, ensure that you switch off all the flames, air conditioner, as well as the pilot light. Ensure that you open the doors of the cabinets and the closet. You should also cover all the foods and remove your pets from the house. After the application, it is recommended that you leave the house for approximately four hours. On returning, open all the windows and doors to aerate the rooms.
  • When applying the product, ensure that you target the bedbugs and fleas hiding regions. You should spray deep into the bug’s hiding zones. When spraying, you should ensure that all foodstuffs in the house are covered. Spray the surfaces until they become wet and then allow them to dry to establish the protective barrier.

The spray is meant to be used indoors only. Some of the places it can be used include the home, non-food sections of restaurants, hotels, motels, nursing homes, schools, hospitals, offices, kennels, and warehouses.

Outdoor Use. This is a rare use of the product. Where there is a substantial infestation, the product can be sprayed around the house to prevent the re-entrance of the bedbugs and fleas into the house. Regions susceptible to flea infestation such as dog kennels should also be sprayed. You should, however, avoid spraying the gardens since the product is harmful and should not be consumed by human beings in any form.

The Benefits of Using Raid Max Bed Bug Spray

Getting rid of adult bed bugs won’t get rid of an infestation. The eggs they leave behind will hatch and produce a new population. The Raid Max Bed Bug & Flea Killer targets different life stages of the bug to help you eliminate the entire population.

This spray also kills fleas. But that’s not all. It’s also excellent at controlling ticks, dust mites, carpet beetles, lice, and clothes moths. It offers a cheap solution to your indoor pest problems.

The spray comes with an extender wand that’s very easy to use. The wand can fit into cracks, crevices and other confined areas where bugs hide, giving you more precision when applying the product.

By allowing you to direct the poison onto the insects more accurately, the wand can significantly reduce the amount of spray that gets into your home’s air. As a result, it helps prevent you and your family from inhaling fumes from the product.

The Pros and Cons

The Raid Max bed bug and flea killer has its own pros and cons. The pros, however, exceed the cons making it effective and reliable. This product has various features that make it more efficient than competitor products.

Every product has some disadvantages; Raid Max is not an exception. The product’s disadvantages can be reduced by closely following the manufacturer’s guidelines when using them.

Some of the unique features and the primary disadvantages of the product include:

  • It is a trusted brand. Raid Max has established a name due to its high-quality and effectiveness in the elimination of bugs. Numerous reviews indicate satisfaction among its user. As such, the product is a guaranteed method of eliminating the bugs where other products have failed.
  • It kills the insects at their different stages of development. The broad spectrum of activity increases the rate of elimination of the bugs. Additionally, Raid Max is formulated to destroy the insect’s eggs which give a guarantee of complete removal.
  • It offers a protective barrier for up to 12 months. Bed bugs and fleas can re-infest your home even after successful elimination. When this happens, it becomes paramount to establish a barrier that will reduce any chances of re-infestation. Raid Max forms this protective barrier with assured bugs repelling success.
  • Highly available at affordable prices. The Raid Max products are readily available in online stores and physical locations. Despite their high-level of effectiveness, the products are affordable.
  • Can be absorbed through both the cuticle and through direct ingestion. The feature is unique as it increases the chance of absorption of the molecules by the bugs. Other insecticides are absorbed primarily through the cuticle. Additionally, the CNS mechanism of action is irreversible and once absorbed, the bugs will have to die.
  • When used outdoors, Raid Max potentially eliminates even the beneficial insects such as the honey bees. While this is a sign of the strength of the product, it can be devastating when trying to protect the honeybees and other beneficial insects from the harm inflicted by the product.
  • Advanced care should be taken to avoid the product’s contact with food. Raid Max should be used very carefully especially when spraying the kitchen and other areas with foodstuffs. The foods should be covered to prevent instances of poisoning. The owner of the house may also be forced to evacuate the home for approximately four hours. Despite this inconvenience, the overall benefits are worth it.
  • The product cannot be used in a garden. It’s important to note that the product is harmful and should not be applied in a garden with crops that are to be utilized in the kitchen. It would be wrong to spray your kales and then use them to prepare supper for your family since it could lead to poisoning and possible deaths.

Generally, this Raid Max bug spray has more positive reviews than negative ones and is worth considering. Although there are high chances of this product helping you deal with bed bugs, you’ll also have to be diligent in applying it.

Make sure you spray everywhere these unwelcomed guests may be such as the mattress seam and all the crevices around your bed. Remember these sneaky creatures also like to hide in other areas apart from your bed such as in chairs, couches, clothes, and behind dressers. Treat any area you find they’ve infested.

You may also need several application treatments to send these pests packing. If you see them again after a couple of days or weeks, make sure you spray again. It’s also a good idea to try looking for them in areas you might not have checked the first time you sprayed.

Do not allow bed bugs and flea to subject you to pain and suffering. The bugs can be a menace when they develop resistance to certain insecticides leaving you with minimal options to explore in their elimination effort. Raid Max is an ideal product for you!

You can also increase the effectiveness of this Raid spray by combining it with other bed bug control methods such as trapping and vacuuming.

Spraying for Bed Bugs Did Not Work

The gentle man who sprayed told me the spray was good for three months, well it’s been four months. I always thought the neighbors had them from seeing bites but they denied it. Anyway, four months later after being sprayed I found a bed bug on my bed. I am going to be sprayed again, but if the neighboring unit has them am I looking at being sprayed every three months.

Answer:Okay. a few things to start: bed bugs are not easy to control and simply spraying will not do it, if the company only sprays and has little experience in bed bug control, it is not going to happen, no spray last three months, no matter what it is or what the pest is, nothing last three months, unless every unit is treated (or both units) at the same time (at the same time. ), then you will simply chase them from one to the other, there is never just one. baby or not.

A thorough treatment of both units by a company that has experience in treating bed bugs is necessary, and the second treatment is done within 10 days; more than simply spraying will have to be done. dusting, maybe some traps to monitor for bed bugs, treating in wall voids of the bedroom, and discarding the infested couch.
