There are cockroaches at home, and there are a lot of cockroach pills, but they have no effect, what

There are many ways to eliminate cockroaches, but the so-called cockroaches are resistant, but in fact, they are cutting corners with cockroach exterminators, so if there are conditions, they can also process themselves: prepare a piece of flour, boric acid, onions, milk. Then chop the onion, squeeze it into juice, add it little by little to the same amount of flour and boric acid, and knead it into small balls by hand, (1 cm in diameter.)

If you add some milk, the effect will be even better, and put the prepared boric acid dumplings in places where cockroaches are frequented, such as cupboards and kitchen corners. The smell of onions can attract cockroaches, as long as it eats a bite, boric acid will cause cockroaches to dehydrate and die, although the boric acid dumplings are as hard as stones for a few days, but the effect remains the same, it should be noted that children should not eat dumplings by mistake, the effect of killing cockroaches is very good in this way. In addition, it can also catch cockroaches, which is not costly, effective, and environmentally friendly.

The tail whiskers of the cockroach are its guards**, it is an air vibrator, it can sense where the enemy is coming from, so it is not easy to catch it, often as soon as it raises its hand, it will quickly escape, so it should take the method of striking east and west, first make a "shhhh

Your cockroaches already have antibodies to that cockroach pill, and you can try a different cockroach pill.

There is a cockroach medicine! You can try it, the effect is okay!

Spray some pesticides! It should be better.

It is possible to replace it with another cockroach medicine. In the case of small cockroaches with cockroach medicine, it is generally because the cockroach has become resistant to cockroach medicine, and other drugs can be replaced at this time.

It is recommended to use dinotefuran cockroach drugs, and the proportion of ingredients is a little better.

Dinotefuran is a nicotinic insecticide developed by Mitsui Corporation of Japan. The chemical structure is very different from that of existing nicotinoid pesticides. It has the following features:

1. Safety. Dinotefuran is very safe for mammals, and its acute oral LD50 for mice is about 2500mg kg.

In other words, a 10kg pet will be fatal if it consumes about 25g of dinotefuran at a time. The dinotefuran content of cockroach medicine is equivalent to eating 5kg of cockroach medicine. In fact, dinotefuran cockroach medicine is less toxic than table salt.

Therefore, dinotefuran cockroach medicine is generally safe for cats, dogs and people, and pets at home can also be used with confidence.

2. Low resistance of cockroaches.

Dinotefuran, as a third-generation nicotinoid insecticide, has no cross-resistance with other nicotinoid insecticides. At present, it has excellent effect on the control of cockroaches, and there are almost no reports of drug resistance.

3. It has high insecticidal activity at low doses.

Cockroaches have a strong ability to reproduce, which requires cockroach medicine to have the ability to infect and kill.

The current cockroach medicine will take advantage of the characteristics of cockroaches eating the corpses and feces of their companions, and after the cockroaches eat the medicine, they will not die immediately, but after returning to the nest and dying, they will poison and eat the cockroaches that eat their corpses again.

This requires that the compounds of the cockroach medicine have high insecticidal activity at low doses, after all, the concentration of the cockroach medicine will be greatly reduced when it enters the cockroach's body. In order for cockroaches that eat their carcasses and feces to be killed, the compound needs to have high insecticidal activity at low doses.
