How fast can bedbugs multiply? – Part 2

Last time we reached a conclusion that it would take only a few months to have a heavy infestation, today we’ll see how the infestation can be control by limiting the food supply.

First of all, here’s some background information:

Therefore, a total of seven blood meals are required to create an adult bedbug. You may argue that the male might mate multiple times and the female might lay a few eggs after each meal. This may be true. However, nymphs feed a lot more frequently than once every nymphal stage, and the adults need to feed just to survive. Therefore, 7 meals are actually very conservative estimate. Let’s assume all meals follow the "breakfast, lunch, dinner" pattern of three bites, then, to generate a new adult bedbug, they will have to bite you at least 21 times.

Now let’s assume that you get bitten three times a day (That’s a lot of bites considering that you have effectively protected yourself). You will have 21 bites per week, just enough to generate a new adult bedbug. In three months, you will have 14 bedbugs, including the original 2. Remember without limiting the food supply, the number reached 1000 in three months? That’s 14 versus 1000, what a difference? Also, after 10 months, some bedbugs will start to die, since the growth is linear, whenever a new bedbug is created, another one will die, and the population will stop to grow.

If you have successfully isolated your bed and living areas, you shouldn’t get any bites at all.

Bedbugs cause problem because they bite us, but this also makes them vulnerable since they rely too much on our blood. By protecting ourselves, we can effectively eliminate their food supply, break their reproductive cycle, and make them more vulnerable to insecticides (due to lack of nutrition).

You might be advised not to isolate your bed for two reasons:

The first reason does not make too much sense to me. It’s too big a price to pay to feed them with your blood and let the population grow just so they won’t spread to other rooms. Caulking is an effective way to prevent them from spreading by the way.

As for the second reason, the strategy sounds good and might be working at this point. But there are questions you need to ask yourself and things you need to consider:

I have just found out I have bed bugs, I just move into my new apartment and found at least 10-15 dead and 5 adults. Once I realzied what they were I trash my box spring and throw out 80 percent of my sheets, the I vacumed and washed most of my clothes. I thought I solved the issue untill two weeks later I found one that just feed on me and another near my bed on the floor, anyways I read alot about bed bugs and cant figure out where the nest is and is there any way I can kill off the few that are left before they spread. And thanks to your spread sheet I have a really good idea on how long and how about these little pain in the butts will take.

How Fast Do Bed Bugs Grow?

Bed bugs feed on humans while they’re sleeping. These pests can be found in almost any area where people congregate including houses, hotels, offices, and stores. Since bed bugs can become a major pest control issue, you may want to know how quickly bed bugs grow.

Bed Bug Pattern

Bed bugs can easily hide behind cracks, box springs, baseboards, and folded areas of beds. These insects consume a blood meal during the day and it typically takes five to 10 minutes to gulp down the blood. After they’ve fed, they maneuver to isolated spaces where they hide for five to 10 days. Throughout this lifecycle, they do not get fed. This is the time for them to digest their meal, mate, and lay eggs.

Preventing Bed Bugs

There are various ways that you can prevent bed bugs. Make sure that you check your bed sheets for blood spots and refrain from bringing home used furniture such as box springs and mattresses without completely inspecting for signs of bed bug infestation. If you have pets, routinely examine the areas where they sleep for signs of bed bugs. It’s wise to obtain a home inspection report in Atlanta, GA, if you’re in doubt.

What Happens Once Bed Bugs Are in Your Home?

As soon as bed bugs enter your home, the infestations can take a few months before it becomes a major issue. One female bed bug who has already mated can populate your home with additional bugs. The female will lay approximately 100 eggs within the first month. By the end of the month, there will be about 60 developing infant bed bugs and another 40 eggs. There are various home inspection rates in Atlanta, GA, for getting rid of these bugs.

How Fast They Spread

At the end of month two, the population grows to 10 breeding adults with many eggs and 200 developing bed bugs in various stages. At this time, you may observe small, reddish-brown colors and dark specks of dirt on your bed sheets. In the third month of infestation, the population flares up. There will be a community of 100 breeding adults, about 500 eggs, and thousands of developing bugs. Additionally, some of the bed bugs will begin to maneuver to other rooms in your home. Within the first six months of a pregnant female bed bug entering your home, it’s very possible that you will have an infestation in every room. By this point, the population has grown to more than 8,000 breeding adults, about 60,000 eggs, and tens of thousands of developing bugs. With infestations, it’s best to contact a professional pest control service. You should obtain a home inspection quote in Atlanta, GA, prior to hiring anyone.

A home inspection service in Atlanta, GA, is done by an individual who is licensed to perform inspections to determine the possibility of damage caused by bugs, insects, or termites. Most of the products used by pest professionals are very effective and the chemicals are considered to be safer.Home inspection prices in Atlanta, GA,can vary.

Bed Bug Life Cycle

Bed bugs are nocturnal, reddish-brown insects that feed on the blood of humans and other warm-blooded animals. These wingless insects have dorsoventrally flattened bodies that allow them to hide in areas such as floor cracks, carpets, beds and upholstered furniture.

A bed bug’s life begins with an egg, grain like and milky white in color. Female bed bugs lay between one and five eggs each day and may lie up to 500 eggs within one lifetime. Eggs are laid singly or in clusters and are placed within tight cracks or crevices. The egg is approximately 1 mm in length and is comparable in size to two grains of salt. Within two weeks, eggs hatch and immature bed bugs begin immediately to feed.

Nymphs

These young bed bugs, or nymphs, pass through five molts before reaching maturity. Although nymphs appear similar to adults, they are smaller in size and are not yet sexually mature. Young nymphs are also yellow-white in color, while older nymphs and adults are reddish-brown. In order to complete a molting stage, each nymph requires a blood meal. At room temperature, nymphs molt and become adults within five weeks.

Adults

Upon reaching maturity, bed bug adults often make weekly feedings.


Adult Bed Bug

How Long Do They Live?
The life span of a bed bug most commonly ranges from four to six months. However, some bed bugs may live up to a year under cool conditions and with no food.

How Long Does It Take For A Bed Bug Infestation To Develop?

ByChris Williamson February 6, 2012.

I was recently sent to a job to inspect for Bed Bugs. Previous tenants had been treated for bed bugs and have moved out. Management wanted to know two things: How long has the unit been infested, and were there any live beg bugs. Inspection for bed bugs can be difficult as most units are full of furniture and belongings, this unit was vacant and empty. With full access to all areas of the unit the extent of the infestation was more clearly defined.

Bed bugs, the scourge of the rental industry, are small insects that feed exclusively on human blood. Long lived and easily spread, bed bugs secretive lifestyle makes detection difficult. Relatively few bed bugs start an infestation. In fact, if a male bed bug is the only hitchhiker, no infestation will develop. Only female bed bugs are able to lay eggs. A mated female can lay around 3 eggs a day if feeding is available, laying more than 300 eggs in her lifetime. Small white eggs are cemented to discrete surfaces, near a host, and hatch in about 10 days. Nymphs resemble adults but are much smaller. In order to grow, or molt, nymphs must acquire a blood meal. Depending on the temperature, it takes nymphs about 100 days for the five molts to occur before mating can take place. Roughly 1.5-2 months are required for a complete cycle from egg to mated adult bed bug. Adult bed bugs live about 10 months, although without a host, bed bugs may live over a year.

Bed bug infestations develop slowly. At first very few insects are present, feeding intermittently on the host and may not be noticed. Bites are sometimes overlooked or blamed on some other pest species like spiders. Secretive adults may not be noticed as they feed on sleeping hosts. Over time though, evidence builds up. Bed bugs are gregarious, and can be found living side by side in harborage sites. Great numbers of nymphs and adults can be found together. As these sites become more active, females will migrate to areas of less activity to lay eggs. Male bed bugs want to mate constantly with females, driving them away. This behavior is believed to be what makes bed bugs “spread out” into new areas. Large populations also use up more and more of the hiding spaces near the host, and are forced to seek shelter farther from the feeding site. All the while the bed bugs are pooping. Bed bug feces is little more that partially digested human blood. Fecal spots form as the bed bugs move about and accumulate in and around the harborage sites. Fecal spots are usually clustered, and may have a small “smear” at one side, indicating the direction of the bed bug’s travel. In heavy infestations there may even be a discernable, almost sweet odor, due to large amounts of feces and aggregation secretions. As bed bugs molt during the growth process, the smaller old skin is shed and a new larger skin forms. These skins are also left where they fall and may accumulate over time. In heavy infestations, there may be considerable numbers of these cast skins.

Now, back in the unit to be inspected, I am looking for evidence. I begin with a cursory look around. With a bright flashlight, pliers, and a screwdriver in hand I start with the ceiling edges and walls. As harborage sites become full, bed bugs will end up in corners and on walls. Right away I begin to notice some fecal spots on door frames and at lower closet edges. No activity behind outlet covers, or under carpet in the 2 bedrooms, 12-25 dead bed bugs noted on the bed room floors, some fecal spots on lower closet door and door frames, no live activity. Bases of all 3 hall closet door frames also had fecal spots, dead bed bugs, no live activity. As I began to examine the living room, there seemed to be more and more dead bed bugs, and fecal spotting, increasing as I got over to the baseboard radiator. Fecal spotting all over the metal housing and adjacent molding told me I was getting warm. When I dismantled the housing and pulled the carpet out from under it I hit pay dirt. 1000’s of cast skins, large pockets of blood stained carpet(major harborage site), and hundreds of dead bed bugs were deposited under the carpet and heating unit. There must have been a couch or bed right there. As the infestation grew, the bed bugs spread out along the floor edge and eventually found the bed rooms, where there was much less fecal spotting etc. In my opinion, the focal point of the infestation was the living room. As far as a time table is concerned, based on the life cycle, amount of fecal spotting, and the number of cast skins noted, the infestation was more than a year old, maybe older. 2 live bed bugs were found, although upside down, on the kitchen floor. This indicates that the treatment was working, and that bed bug control is almost complete. My recommendation was to re-treat the unit prior to new tenants moving in to ensure that the infestation is gone completely.

How do bed bugs multiply?

You should hate bed bugs because of two reasons: They disturb you and reproduce rapidly. So, how bed bugs reproduce and what can stop them multiplying?

What are bed bugs?

Bed bugs are parasites that feed on blood. They feed only on blood and unfortunately, their main food source is human.

A bed bug has 3 life stages and its size varies from 1 to 6 mm depending on its stage. You can find more information about bed bugs stages in this post: bedbugdetected.com/bed-bug-life-stages

Physical features of bed bugs are below:

  • They are flat and oval-shaped
  • Half-winged (so little useless wings so, no wings at all)
  • Reddish brown colored (More reddish after recently fed)

What do bed bugs look like?

They are not microscopic creatures so, you can see them with naked eye. What you have to know about bed bugs firstly is they can’t fly or jump which means that if you see an insect flying or jumping, you can eliminate bed bug option easily.

Bed bug eggs

Here is a video showing bed bug eggs:

Bed bugs aren’t mammalians which means they multiply by laying. Bed bug eggs can be differentiated from other bug eggs with their shapes and appearances on the floor.

Bed bug eggs are yellow white, they stand together and glued to the surface, mostly in cracks. The most distinguishing feature of those eggs from the other bug eggs is “glue”.

Other places where bed bugs lay their eggs are:

  • Behind walls
  • Inside clothes
  • Mattress
  • Behind wall papers
  • Other places near to their food source

Beg bugs male/female ratio

This is important because reproducing activity of beg bugs depend on the number of females. After laying their eggs, the number of female and male eggs hatching is almost the same: 1:1 ratio.

Success hatching ratio of a female is usually more than 95 percent.

How fast bed bugs spread?

Laying ability of a female adult bed bug depends on how much it feeds. So, more blood they can have, more eggs they will produce.

After a female bed bugs feeds enough once, she will produce 1 to 7 eggs per a day for next 10 days.

Eggs will hatch in 7 to 10 days if the air condition is suitable for them, otherwise hatching time can take up to 30 days.

So, a female bed bug can hatch 100 to 500 eggs in her lifetime which means they will reproduce rapidly and if no action is taken, the invasion will be inevitable.

How fast bed bugs grow?

After hatching, new born bed bug will have 2 more life stages. First will be nymph and this stage has 5 instars in it.

They will need a month in average to become an adult which has a body size more than 5 mm.

How long bed bugs survive without feeding

The main reason what makes bag bugs invasive is their resistance to hunger. They can survive without feeding at least for months, nevertheless it was observed that they can live without feeding for more than a year in some cases.

Ideal temperature for bed bugs

Ideal environment for bed bugs is where the temperature is between 65° and 85°. So, their activity will reduce below 65° and above 85°.

What prevents bed bugs from reproducing?

Under these conditions, their reproducing speed gets slower or ends:

  • If they can’t feed enough
  • If they are not close to their food sources
  • If the environment temperature is not between 65° and 85°.

Conclusion

What you must know about bed bugs reproduce are:

  • They usually start mating after 1 month they hatched.
  • They multiply by laying.
  • Their eggs are glued and in group.
  • Hatching success for the eggs is more than 95 percent.
  • An adult female can lay 100 to 500 eggs during her lifetime.
  • They are more reproductive during ideal condition: When the feed enough and it’s 65° and 85° around.
  • If no action is taken on time, you must face a bed bug invasion.
