Bug larvae: how to look, how to get rid and species

Everyone knows that bedbugs are small, bloodsucking parasites that enter living quarters in various ways. Getting rid of them is quite problematic, as they multiply with astonishing speed. And it is necessary to destroy not only adults, but eggs, and larvae of bedbugs.

Features of appearance and physiology

Nymphs of these parasites appear no later than thirty days after the laying of eggs. This period depends on many external factors and under favorable conditions is reduced to four days. Interestingly, the larvae of domestic bugs also feed on human blood.

Externally, nymphs are very similar to adult insects. They can be distinguished only by a lighter color and small size. Nymphs have an elongated and slightly flattened body. Usually their size does not exceed four and a half millimeters.

But physiologically the bedbugs and their larvae differ greatly from each other. The latter can not reproduce, need frequent meals, are highly dependent on the temperature of the surrounding air, and move slowly and little.

What is the difference between a larva of a bed bug and other insects?

To establish the species affiliation of a particular parasite, it is not necessary to be a professional entomologist. To do this, it is sufficient to simply know the basic characteristics of the bug nymph. For example, from the young cockroaches they are distinguished by the fact that they are more mobile and agile. In addition, their body is colored in a lighter shade, and on their cephalothorax there are no white spots.

Unlike the larvae of ants, the bug's nymph does not have a pronounced narrowing that separates the abdomen from the cephalothorax. With fleas they can be confused only at the earliest stages of development.

The appearance of nymphs

Having figured out what the larvae of bedbugs look like and how they differ from the rest of the domestic parasites, we need to say a few words about how they develop. Initially, the female, full of blood, lays eggs. At the same time, it uses a specific secret that glues them to the nest and to each other. This process takes about five days.

The size of the masonry it depends on the season, temperature and weather conditions. Under favorable conditions, one individual can lay up to twelve eggs. And their number is affected by age, body weight and the degree of satiety of the female. Five days later, larvae of bedbugs appear. They look like plastic vessels. Freshly hatched young animals are immediately ready to be fed with blood.

Stages of development

Under favorable conditions, it will take four to six weeks to convert a newly hatched individual into an adult insect. This process consists of five steps. And on each of them the body of a young parasite increases in size by half a millimeter. If the larva in the first stage of development has a length of just over one millimeter, then at the end it reaches almost half a centimeter.

A grown-up nymph must say goodbye to his shell, because he is not capable of stretching. This is the main reason for molting. After each change of shell, the body of the insect becomes more and more dark. It is interesting that all the transformations take place after the larva is energized with another portion of blood.

Where are the nymphs of bedbugs hiding?

It should be noted that identifying them is quite problematic. This is because they eat in the early morning hours, when people are still asleep. In the saliva of larvae of bedbugs there is no anesthetic secret, therefore its bite is always accompanied by severe itching and pain.

By analogy with adult insects nymphs settle in various secluded corners of the apartment. They try to choose places with the most favorable temperature regime. Therefore, most often they can be found in mattresses and sofas.

Features of the larva shell

Invulnerability of eggs of bedbugs is explained by the fact that they are hidden under strong protection. Their shell is resistant to the effects of potent chemicals. Through its walls does not leak liquid.

In addition, the surface of eggs is immune to sudden temperature fluctuations and to mechanical damages. If you try to break them down with something heavy, then your attempts will not succeed.

The main difficulties arising in the process of killing nymphs

As mentioned above, the larvae of the bugs resemble rice grains of slightly curved shape. If you look closely, then from one side you can see a small dark spot. It is in this place that there is an exit for a matured individual.

Destroy nymph bugs is not as simple as it might seem at first glance. Especially if they were not identified immediately and have already managed to settle in a new place. If adult parasites can be destroyed with potent chemical preparations, the larvae are so well protected by a strong shell that their destruction turns into a real problem. They calmly survive the effects of poisons and continue to develop in a temporary shelter.

To destroy the larvae of bedbugs has not turned into an endless occupation, it is necessary to ensure that all nymphs and adults are exterminated. Otherwise, all your actions will become meaningless. As young females will constantly lay eggs, from which new parasites will appear.

How to get rid of bug larvae?

It should be understood that in this case it is impossible to apply the methods used to control adult parasites. All of them are ineffective and operate only for a short period of time.

To destroy the larvae, you can use such poisonous chemicals as dichlorvos, carbofos and pyrethroids. However, when working with these substances it is important to comply with all rules and ensure the safety of tenants.

Also a good solution may be the use of insecticides, sterilizing insects. However, such funds are almost not found in free sale. As a rule, preparations containing such components are available only for professionals.

Near the nests of bedbugs you can scatter powders, killing these insects. Then the hatching larvae will immediately fall on the deadly "glade". However, when choosing such drugs, it should be remembered that most of them are unsafe for humans and pets.

How to avoid the appearance of parasites?

To protect your home from bloodsucking insects, you need to refrain from visiting places of potential congestion of bedbugs. These include cheap hotels and houses with unsanitary conditions. Also, you should not invite people who have parasites in their apartments. Since even one or two individuals who accidentally fall into your apartment, will quickly become the ancestors of the whole population.

Experts recommend not neglecting the systematic wet cleaning of their homes and checking the condition of beds, sofas and other beds for the presence of traces of bug life. It is also necessary to regularly wash the bedding. And do it only in hot water.

To scare away bloodsucking insects and prevent their migration from neighbors, it is recommended to keep birch brooms and dried tansy bunches in the house.
