Eggs of bed bugs, house bugs: how they look, how they lay, how they hatch and at what temperature they die. Photo (10 pcs.)

Reader Question:

Sarah

I've been fighting bedbugs for six months now. I have tried various methods. There is no result, after a few weeks I feel itching again and find bites on my body. I tried to call exterminators to treat the entire apartment. After that the bedbugs kept coming back. At home I can smell the chemicals all the time, all the surfaces are covered with preparations.
Хочу понять, что я делаю не так. Выдерживаю 2 недели, только тогда провожу уборку дома, чтобы химикаты подействовали. Еще использую разные препараты, пока ни разу не применяла одно и то же средство дважды. Возможно, паразиты каждый раз приходят от соседей, я просто не уверена, что это потомство тех же особей, что обитают у меня дома. Хотела бы узнать, как выглядят яйца клопов, чтобы уничтожить личинок до появления из оболочек. Помогите разобраться, пожалуйста. С уважением, Сара.

What the eggs of bed bugs look like. Distinguishing characteristics, description. Photo of bedbug eggs

It is believed that Egg The parasite of this species is oval in shape. But it is necessary to look closely. It may turn out that because of the lid on one side, the egg actually looks like a cup (here the formation is slightly truncated). This opening is hermetically sealed. When the time comes, a larva emerges from it. The color of the egg shell bedbug changes from milky white (at the clutch stage) to light brown. The formation darkens closer to the transition to the next stage of development.

How big are the eggs of bed bugs

Adults parasitesThe human house dwellers are clearly visible on the surface. However, their offspring, on the contrary, are almost invisible due to their light color and small size. So, the eggs bedbugs do not exceed 1 mm in length. Rarely, they may be a tenth of a fraction less.

Where bed bugs can lay eggs

Parasites choose to live in hidden areas. This is also where the female lays her eggs, mostly inside furniture, where the nests are built. But not always larvae emerge from them. If such formations are noticed, they will be destroyed.

To increase the survival rate of offspring, house bugs carefully hide their offspring.

Bed bug eggs are often found in other places: in cracks on the wall, floor, under baseboards, between the elements of furniture frame construction and even inside the upholstery.

Can bed bugs lay their eggs on humans?

The probability of this is extremely low. To make a clutch, the female needs a secluded place, and it is important that it is protected from moisture and light. Here parasite must feel safe, then the hatching larva will be able to survive - it will not be affected by any of the external negative factors. For this reason, pests do not lay offspring on the human body. But it happens that white formations are found on clothing. This is where the eggs of domestic bedbugs only when these things have been in the closet for a long time.

How bed bugs lay eggs

The formation of embryos in the female body occurs due to traumatic insemination. This is a non-traditional mating method. In this case, the male pierces the abdomen of the female. The seminal fluid enters a special organ (Berlese). As a result, the female can procreate without the participation of the male. Mating occurs once in the lifetime of the female insect.

The eggs of bed bugs in the couch and other places the female lays in the number of not more than one or two dozen.

How many bed bugs hatch from one egg

The size of these masses is extremely small. Only 1 embryo can develop inside. The probability of several embryos tends to zero. This would make it difficult for them to hatch. As a result, the survival rate of the insects may decrease.

How long do bedbug eggs live

The offspring can stay inside the shells for 1-6 weeks. Then it moves on to the next stage - larvae (young parasites emerge from the shells). It must be kept in mind that embryos do not develop for such a long time (6 weeks). It usually takes 4 to 19 days (depending on the temperature and air humidity). If the environmental parameters change, unsuitable conditions for further development are created, then internal processes are inhibited.

How long before the eggs hatch and turn into larvae

Several scenarios are possible:

• temperature dropped to +14 ° C - the embryo develops for 15-19 days;
• the room has become warmer (+22 ... +26°), the formation of the bedbug inside the shell is accelerated - it happens in 5-12 days;
• the air temperature has risen to +35°C, the rate of embryo formation will increase - it will take 4-6 days.

If there is a cold snap to +5 ... +10°C, bed bug eggs stop developing at these temperatures. They will begin to hatch when the air gets warmer. Lower temperatures (-4 ... -7°C) allow the parasites to survive for six weeks at an early stage of development. Bed bug eggs will not die.

Sometimes they remain viable even longer.

At what temperature do bedbug eggs die?

Embryo insect itself is not capable of resisting the negative impact of external factors. The implementation of the protective function is provided by the shell. But even this barrier is not a guarantee of survival under all conditions.

Critical temperature below zero

A cold snap down to -17° C allows you to get rid of parasites in 1 day. It is possible to take the infected things out into the frost. To avoid having to wait long, it is recommended to affect the pest germs by lower temperatures (-25°C). Under these conditions, the eggs bedbugs die in a few minutes.

The rule of thumb is: the lower the temperature, the faster you can get rid of parasites.

Critical temperature above zero

The limit value is +55°C. In this case Insects inside the protective shell die within minutes. Lower temperatures (+45°C) contribute to the death of the pest in 1 day. If the degrees are reduced even further (+40°C), the embryos can be killed within 1 week.

Question and answer section

To destroy everyone parasites, you need to find out where the bedding bedbugs lay eggs. This will allow you to find them quickly. You can learn about all the subtleties of this process, as well as methods of pest extermination from an expert entomologist. An expert with 24 years of experience answers.

What do hatched bed bugs look like?

Ask a question

"They resemble adults in general features. They are small insects - up to 1 mm. At the early stage they have significant differences: light coloring, and the body is transparent, after eating the digestive tract is clearly visible - bright blood is visible. The larva is at this stage during the first week after hatching.

What does a clutch of bedbugs look like?

Sofia

Entomologist with 24 years of experience

Ask a question

"It is a cluster of eggs, more often there are small clutches. When the young hatch, they are left with empty shells. There can be many such clutches - they are found everywhere where bed bugs live, and you should know what the eggs look like before you start looking for traces of pest activity. This will make it possible to recognize in time which parasites have been found: their excrement remains here, as well as the shells of other larvae, older ones".

At what temperature do bed bug eggs die?

Sofia

Entomologist with 24 years of experience

Ask a question

"We must remember that embryos are well protected. They die only if they are exposed to extremely high and low temperatures: below -17°C and above +45°C. However, under these conditions, pests cannot be killed instantly, it will take several days."

How many bedbugs are in the egg?

Sofia

Entomologist with 24 years of experience

Ask a question

"There is always one embryo inside the shell. When the female is about to lay eggs, she cannot affect the development process of the embryos inside. This is inherent in nature, driven more by the need to ensure the survival of the pests. They do not fight for survival at the embryonic stage, but develop fully.

How do I find bedbug eggs?

Sofia

Entomologist with 24 years of experience

Ask a question

"In most cases, only a fraction of them are detected. Female parasites lay many eggs on different days. The time of hatching is different, which contributes to the constant appearance of new and new generations of insects. If the female makes a clutch in the nest, it is easier to find her here - you need to look for excrement, husks (shells of nymphs). Individual clusters of eggs may remain in remote areas - in crevices of the floor, walls, where a man will not find them.

How many eggs does a bedbug lay at a time?

Sofia

Entomologist with 24 years of experience

Ask a question

"The numbers are always different. This is determined by the conditions of the parasites' existence. Most often 5-10 eggs appear, but there are smaller and larger clutches (from 1 to 19 formations)."

Do cockroaches eat bedbugs and their eggs?

Sofia

Entomologist with 24 years of experience

Ask a question

"These insects are not natural enemies for each other because they do not compete for food. In a human apartment/home, the pests live in different areas and eat different foods. Cockroaches do not attack blood-sucking insects. However, in cases of extreme need, they may find bedbug eggs on clothing, in cracks and other hiding places, and then suck the juices out. This is what happens when roaches don't have enough of their main food sources.

Does steam kill bedbug eggs?

Sofia

Entomologist with 24 years of experience

Ask a question

"This is one way to control such pests. Hot steam will kill insects if the temperature of humid air exceeds +55°C. Then the parasites will die instantly. If the temperature is slightly lower, however, it should take a long time to affect the eggs so that the embryos inside will die."

What color are the eggs of bed bugs?

Sofia

Entomologist with 24 years of experience

Ask a question

"Once the female makes a clutch, milk-colored formations remain on the surfaces. The shell properties change as the embryos develop. The eggs become yellow-brown."

Useful tips from SES specialists, control for successful bed bug control

To banish bloodsuckers pests from the apartment, it is important to follow the instructions for treating the room exactly. You can kill bed bugs only if you use the correct preparations. It is important to choose the right products, killing pests. It is suggested that you ask a specialist about the subtleties of this pest control.

"Public and private pest extermination workers use several effective methods, with hot and cold fogging leading the way. When the eggs are still ripening on the couch, in the furniture frame, under baseboards, and in other remote areas, the toxic slurry penetrates everywhere.

Even if not a classical ovicide is used, but a product with simpler properties, high efficiency of such treatment is still ensured. The larvae will immediately receive a dose of poison when they emerge from the eggs, start crawling, because the insecticide in the form of a suspension penetrates into any crevices where it will contact with the outer covers of the pests.

Deratization

"You need to understand the difference between the services provided by such companies. In addition to insects, they also poison rodents. Deratization is aimed precisely against the latter. In this case, completely different preparations are used. They can remove rats from an object, but there is no guarantee that bedbugs will also die.

"When the procedure of extermination of parasites is carried out, different means are considered. And it is better to apply simultaneously preparations with different principles of action, so as not to cause resistance to the poison in insects. Almost all of them contain insecticides. Those means that do not contain poisonous substances (Hector) can also be used, but as an auxiliary measure that enhances the effectiveness of the main methods. If some of the insects die from the poison, the rest will die from damage to the outer covers and dehydration.

Folk methods

 From home parasites help you get rid of the auxiliary measures. These include improvised remedies. They are less effective when it comes to destroying insectsbut works well enough if you want to scare away pests. This result is achieved by a strong odor.

Bed bug mixes

Effective Recipes:

• turpentine - 150 ml, crushed laundry soap - 50 g, ammonia alcohol - 50 g;
• turpentine and kerosene - 100 ml each, naphthalene - 25 g.

Such substances stain surfaces, so they are applied to cotton pads or rag strips and then spread around the apartment.

Plants with a pungent odor

The most commonly used herbs are wormwood and tansy. Herbs with bitterness are effective in repelling, but they contain natural insecticidal substances that help poison the parasites. Other plants that repel bed bugs:

• geraniums;
• chamomile;
• rosemary.

Vinegar for bed bugs

Such tool is applied in different ways:

• Dot applied in concentrated form to areas where house parasites may be present;
• prepare a solution: mix vinegar and water in a ratio of 1:1, apply it to surfaces (treat a large area).

To kill a bedbug with vinegar, you need to pour a concentrated product over it. In other cases, only a deterrent effect is provided.

Street bugs and their eggs. Photos of bed bugs with eggs on their backs

If we consider street insects, the parameters of the embryo will be different. For example, the eggs look like bedbugs called the pest turtle (of the Scutellum family) is quite different - they are green, rounded formations up to 1.1 mm long. In the marbled pest, the embryo reaches 1.6 mm. It is a stink bug (with a brown pattern). In the soldier bug, the eggs are similar to the offspring of the bedworm. bedbug - white, up to 1 mm long. The embryos of many water pests are larger. However, the size of water vole eggs is the same as those of domestic bedbugs - 1 mm. But in a clutch there can be up to 50 units of such formations.

Ask a question

- Eggs will not die if you briefly expose them to a high temperature source, you need to hold it over the clutch for a few minutes;
- I do not recommend trying to crush bed bugs mechanically, their eggs are small and quite strong, so there is a risk of surviving the victims, better to use a source of steam/hot water or poisonous substances;
- In an apartment with a hot microclimate parasites develop faster, so the number of colonies is greater, to kill all bed bugs, you need to close access to the apartment (ventilation grille, cracks, etc.), and then all tenants to leave immediately, then the insects have no opportunity to escape, as well as to feed.

Conclusion

Eggs bedbugs are characterized by a light hue. On one side they have an outlet for the young - a hole with a lid, which remains hermetically sealed for the time being. To control such pests, it is necessary to learn more about the life cycle, the way they reproduce, and their habits:

1. The eggs are oval in shape, 1 mm in size, and due to the truncated edge on one side they resemble cups to some extent. Inside, the bed bug embryo develops for 4-6 days (under ideal conditions).
2. The rate of parasite formation depends on temperature and air humidity. Its death occurs when temperatures rise to +55°C or fall below -17°C.
3. For disinsection apply professional methods (cold and hot fog), barrier protection. You can deal with insects on your own, using household insecticide sprays, improvised means.
