What does a cockroach s egg sheath look like? What do cockroach eggs look like

A fertilized female cockroach produces a large number of egg sheaths in her lifetime, and the American cockroach.

It can produce up to 50 more, so cockroaches are very fecund. Every 7-10 days, a mature female cockroach can produce an egg sheath containing 14-40 eggs, which are colloidal and hatch between 20 and 37. The higher the temperature, the shorter the incubation time, at a constant temperature of 30, it only takes 20-30 days, and the longer can exceed three months.

A female cockroach can reproduce nearly 10,000 offspring a year, up to 100,000.

Normally, cockroach eggs.

The sheath will be carried by the female cockroach on the tail until hatching, and if the cockroach egg sheath is not protected by the female cockroach, the egg sheath will fall off prematurely, and the eggs inside may not hatch. The cockroach eggs are large, white at first, and then slowly turn black, like a melon seed, and the shell is hard, and can only be burned by fire or boiling water. They like to be in the cabinet or in a longer, humid place, such as a place under the refrigerator where there is a certain temperature.

Especially in the cracks of the worn-out sofas.

But cockroaches have the characteristics of migration, for example, if your home has been extinguished, there are no cockroaches, and when the neighbor exterminates the cockroaches, some adults may come to your house to "live". Therefore, "strict prevention" is also the key. "Plugging holes and wiping cracks" is the key, and you should also be extra careful when moving, the eggs of cockroaches are laid in the egg sheath, a black-breasted cockroach.

Cockroaches can have up to 40 eggs in their egg sheaths. The egg sheath is a bit like a pod.

It's the same color as a cockroach. These egg sheath sprays can't be killed! Be sure to use boiling water or fire to burn it. Exterminate cockroaches.

The company told everyone that egg sheaths are generally laid by cockroaches in the seams of drawers and cardboard boxes. In order to get rid of cockroach egg sheaths, we need to use regular cockroach extermination drugs in the following two ways.

Deploy cockroach medicine to the area where cockroaches are active at any time to form a protective belt to isolate cockroaches in this area, and even if the baby cockroaches are born, they can be eliminated.

Cockroaches no matter from the **, it eventually sits into a big nest, the main reason comes from the sanitary conditions at home, if the garbage and stove at home can not be cleaned up at any time, it will eventually become an excellent place to nourish cockroaches. This cleaning can not be an ordinary cleaning, the home must be spotless, there must be no food exposed to the outside, any nail to eat the residue, will attract cockroaches.

The egg sheath of cockroaches is formed by the sap secreted by the tail end of the female cockroach, and most of them are sauce-red purse-shaped and red bean-shaped, with a row of small serrated glands called dentates on the upper edge. The eggs of cockroaches are narrow and elongated, milky white, translucent, arranged in two neat rows in the egg sheath, and the head of the embryo is slit towards the hole.

Cockroach eggs are narrow, elongated, milky-white, translucent, and arranged in two neat rows in the egg sheathThe head of the embryo is slit towards the hole. Cockroach eggs are small white granular forms that grow in the cockroach egg sheath, which is a hard shell that protects the cockroach eggs.

Cockroach eggs are laid in the tail end of the female cockroach after the male and female cockroaches mate, and the eggs are laid in it. A female worm can lay more than 10 eggs and more than 90 egg sheaths. In an egg sheath, 10 small cockroaches can be hatched at least and 50 small cockroaches can be hatched at most, which is related to the cockroach species.

The nymphs that have just hatched from the egg sheath are gathered around the egg sheath, which is white, and then the color gradually darkens, and spreads out to move, the nymphs are similar in shape to adults, but the body is small, wingless, and the sexual organs are immature. Nymphs develop slowly. It must undergo multiple molts to grow gradually, and the number of antennae and tail whiskers also increases with age.

After the last molt, the nymph grows wings and emerges into adults.

Cockroach eggs are hidden in the cockroach's egg sheath, the egg sheath is a hard shell, the drug can not penetrate into it to kill the cockroach at all, and there are some drugs that are killed by cockroaches taking medicine, and cockroach eggs will not take medicine at all, cockroach medicine can only kill the mother of the cockroach, the cockroach eggs and the mother are separated, and the drug cannot directly kill the cockroach eggs.

Although cockroach eggs cannot be killed directly, we can kill them by waiting for them to multiply and become adults. This requires the choice of a cockroach medicine that exterminates cockroaches for a long time. Because it takes time for cockroach eggs to breed.

After using the drug, the effect can be managed for about half a year, and when you use it, you can use the medicine in all the places, and wait for the cockroach eggs to breed and become adults, and you can kill them after taking the medicine.

This way there will be no further breeding. In addition, after the cockroach dies after taking medicine, the live cockroach will eat the dead cockroach and slowly die, through the mutual infection between cockroaches, and finally all the cockroaches can be eliminated. After this batch of cockroach eggs is bred and killed, they will not reproduce again, so that the effect of completely eliminating cockroaches can be achieved.

Cockroach eggs are narrow, elongated, milky-white, and translucent. A female worm can lay more than 10 eggs and more than 90 egg sheaths. In an egg sheath, 10 can be hatched, and more than 50 small cockroaches can be hatched, which is related to the cockroach species, and their fecundity is very strong.

Cockroach egg characteristics:

1-2 days after the female lays the egg sheath, choose a relatively hidden place, first bite into a depression on the surface of the object, lay the egg sheath in it, and then use sticky saliva to mix with crushed wood chips or paper and other pieces of paper to cover the egg sheath. Sometimes saliva is used to stick the egg sheath directly to the roosting place, such as the corner of a cupboard, wooden (cardboard) box and table, or in a pile of clutter. These egg sheaths contain sufficient nutrients to meet the needs of embryonic development.

The oviposition sheath method of American cockroach and black-breasted cockroach belongs to this type; After the female lays the egg sheath, she drags it on the ventral end and does not lay it until the nymph will hatch from the egg sheath, and then it will fall off from the mother.

Cockroach eggs are narrow, elongated, milky-white, and translucent. A female worm can produce more than 10 eggs, more than 90 egg sheaths, 10 eggs in an egg sheath, and more than 50 small cockroaches, which are related to cockroach species, and their fecundity is very strong.
