What does the cockroach look like? How to get rid of cockroach larvae

In ancient times, the cockroaches were treated with reverence. Moustached insects were considered a sign of prosperity in the house. Today the situation has changed dramatically. Everyone knows that dangerous pests not only spoil food, but are also capable of carrying harmful bacteria and microbes. A cockroach can climb into the ear, bite a person and even damage the wiring.

The saddest thing is that it is not so bad to get insects out, it's necessary to take care of their offspring. Otherwise, a couple of weeks after the destruction of the pest, the larva of the cockroach will crawl out of the egg hidden by the female. And all the problems will begin again.

What do the larvae of cockroaches look like?

All "mustachioed saboteurs" undergo three stages of development:

• egg;
• nymph;
• Sexually mature specimen.

Eggs adult female wears on itself up to their maturation. Then he puts them in a secluded place (for example, under the plinth). A few weeks later, nymphs hatch from the masonry. This is the larvae of cockroaches. The photo shows that young pests are born white, but after a couple of hours they darken.

Nymphs live together with adult insects. Their food is shared, their behavior is similar. The only difference is that they do not reproduce.

Reduce the population of "kitchen raiders" can, destroying the younger generation. For this you need to know what the larvae of cockroaches look like. It turns out, it's very simple. They are similar to adults. Only nymphs are smaller in size and have a darker color. And during growth they throw off their shell, that is, they molt 5-6 times.

Adult cockroaches become at the age of 2-3 months, depending on their kind.

Red pests

In our latitudes, most often there are red cockroaches - the Prusaks. Although initially it is tropical insects. They even have wings. What pleases you - moustached pests do not fly. Maximum they can balance with their help when falling from a height.

The larva of the red cockroach also has wings and a mustache. By the way, it is the mustache that allows insects to receive information about the external world. Having damaged this tactile organ, the insect will not be able to fully live.

Adult individuals usually grow to 1-1.5 centimeters in length. Nymphs, respectively, are even smaller. It is the miniature that allows the "barbel" to hastily hide from human eyes. Skirting, cracks in the wall, ventilation, space under the stove are ideal places for red pests.

Like an adult, the larva of a cockroach feeds on the remains of food, bread and sugar crumbs. During the day, the insect "sits" in cover, and on the "hunt" comes out at night.

Currently, red cockroaches are common on all continents. The main condition for their survival is the plus temperature.

Black cockroaches in the kitchen

Much less often in residential premises there are black cockroaches. They are also called American or kitchen.

These insects are almost twice as large as the cockroaches. They also differ in coal color. The larva of the black cockroach is also larger than the red nymph.

"Americans" also have small wings. Young individuals and females do not use them. Males, in turn, have long enough wings, they help them to jump for long distances.

It is believed that it is easier to destroy black cockroaches than the Prussians. Female, laying eggs, leave the offspring unattended. Two weeks later, larvae should appear from the masonry. If during this time the eggs will find other species of cockroaches, they are eaten by "relatives".

By the way, black insects, like redheads, prefer to reproduce indoors. Although they can live in nature. The main thing is that the temperature does not fall below 0 degrees.

How many larvae wait from one insect?

People say: "I saw one cockroach, so there are at least ten of them." Frightening is the rapid reproduction of mustached pests. To understand the scale of the problem, you need to know the answer to the question: how many larvae lays the cockroach?

It is impossible to calculate the exact number. With an average standard of living, the number of nymphs in the clutch will correspond to the number of eggs. If the female seems that the conditions for the continuation of the family are unfavorable, then she drops the capsules with the offspring in advance.

With good temperature and sufficient nutrition, several insect larvae can ripen in the egg. In addition, cockroaches are able to regulate the number of offspring.

The number of clutches depends on the type of insect:

1. The Prusak lay 25-50 eggs at a time, during life they are able to leave offspring up to 12 times.
2. Black cockroaches chop off almost 2 times less eggs - 12-18, but for their lives leave 22 masonry.

The most dangerous insect is the pregnant female pest. Killing herself, she manages to drop eggs, which are almost impossible to destroy. Another sad fact is that the cockroach larva is born into an already independent individual. Thus, the struggle with kitchen saboteurs turns into an endless marathon.

Why are cockroaches so tenacious?

Scientists believe that cockroaches appeared on Earth more than 350 million years ago. And, probably, as many still live.

The persistence of insects is explained by the following facts:

1. For the continuation of the genus, the opposite-sex cockroaches only mate once. Sex cells of a male individual can be stored in the body of a female up to 4 years.
2. Without water, a pest can survive for a week, without food - a month. For a full life, "barbel" will be enough drops from the tap, and they can feed on plain paper or cardboard.
3. About 40 minutes the cockroach can not breathe.
4. The insect can live up to -5 degrees.
5. The cockroach is able to live and carry the infection, even if he tear off his head. Such an individual dies of thirst and hunger.
6. Radiation is not terrible for them. Ancient pests have a very slow cell division cycle.

Everyone who has ever tried to catch a cockroach remembers that it is a very fast creature. And unsurprisingly, insects run at a speed of almost 5 kilometers per hour. Among other things, adults learned to pass on their experiences to their relatives.

The picture becomes even more desperate, if you remember that eggs are almost impossible to destroy. They are neither cold nor chemicals.

We get rid of the larvae from the store

It turns out, first you need to get rid of adult individuals, wait for 2-3 weeks, until the eggs hatch nymphs. And only after that start a fight with the younger generation. It is necessary to understand how to get rid of the larvae of cockroaches and adults. There are several methods.

First of all, it is recommended to try a variety of traps for insects. This can be a box with 2-3 outputs. Inside the bait is placed, the pest eats it, becomes infected by itself, runs to the relatives and already spreads a deadly infection in its colony.

Sticky and electric traps are capable of destroying only those insects that have run into them. However, these methods are considered the safest.

What can not be said about sprays against cockroaches. Chemicals can only be used if there are no children and pets in the room. It's also worth it to protect yourself by pre-donning gloves, a mask and safety glasses.

Effective are poisonous gels and powders. Nymphs disappear in less than a week. In this case, the famous crayons can not get rid of a large number of cockroaches and their larvae.

Well help ultrasonic scarers. People and animals do not hear them, but insects do not tolerate ultrasound. The price, however, such funds is quite high.

Folk methods of pest control

Those who are afraid of using shop chemistry will come to the aid of popular methods. It turns out that the larva of the cockroach and the adult insect do not tolerate the flowers of ordinary chamomile. The plant is recommended to grind to the state of powder and sprinkle around the apartment.

A more radical method would be to freeze the apartment. Cockroaches die at temperatures below -5 degrees.

In addition, pests have a developed sense of smell. They can not stand the smell of gasoline and ammonia. The combustible liquid can be coated with plinths and corners. And wash the floors with ammonia.

Boric acid against larvae

Already several generations get rid of larvae and adults with the help of boric acid. This is an effective and cheap way. For the apartment will need about 100 grams of acid.

The powder can be scattered near the sink and around the perimeter of the plinth. The infected cockroach will not only perish itself, but will have time to infect several relatives from the colony.

True, insects quickly realize that this powder should be avoided. Therefore, our grandmothers and great-grandmothers in their time came up with a little trick. They took chicken yolks, mixed them with boric acid powder and molded small balls from them. A bright new bait attracted nymphs and cockroaches, insects fled to "food" and perished.

Of course, ideally it is necessary to call specialists at home, they can disinfect the room completely. Unfortunately, none of these methods does not guarantee that cockroaches will not return, but they will save time for pests.

Preventing the appearance of beetles

To prevent uninvited visitors from appearing in the house, it is recommended to follow preventive measures:

• Keep the apartment clean;
• Do not leave food and drink on the table;
• To conduct general cleaning (inspect secluded places).

In addition, it can be noted that an adult pest, as well as a cockroach larva, can not tolerate the smells of geranium and lemon. That is, to insects do not appear, you can put on the windowsill a few flower pots with flowers. Lemon cakes, unlike other food residues, can be left on the kitchen table and in the sink for the night.
