It s not a big cockroach overrun

It's a German cockroach

It works best with medicated bait.

Poison bait to kill cockroaches Before using poison bait, cockroach food should be removed as much as possible to increase cockroach feeding on poison bait.

Cockroach nymphs have the habit of feeding on adult feces, and adults have the habit of eating corpses and killing of their own kind, and also eating cockroach feces when there is no food. Using this habit, several kinds of "chain killing and poison baits" were developed. After the cockroach eats this kind of poisonous bait, the insecticidal active ingredients in the poisonous bait can be eliminated from the feces, and some of them are still retained in the body.

At present, the imported poison bait products with fiprofen cyanide as the active ingredient are generally slow to act, but have a long lasting effect, and are suitable for conventional cockroach extermination.

Poisonous bait to kill cockroaches is a point application, the application point is selective, can be applied to the cockroach hidden and active feeding places, to achieve high killing effect, can avoid the pollution of pesticides, and greatly reduce the amount of pesticide per unit area.

It is recommended to use the chain cockroach extermination bait of the Benji series, and many of them are said to be very good. However, when sprinkling medicine, you should pay attention, if you have a fish tank at home, don't sprinkle it in the fish tank.

Sprinkle medicine, but I've seen on TV that raising Brazilian tortoises and letting them crawl on the ground will secrete a substance that cockroaches are afraid of, and they will stay away from your home.

Spraying insecticides is the simplest, and you can also raise Brazilian tortoises, they can eat cockroaches, and my few will do.

Once, there were cockroaches in our house very badly, they all came out at night, it was useless to turn on the lights, don't use home remedies. I know that there are electrical appliances on the market that sell cockroach repellent, which are small, similar to mosquito smoke, and rely on radio waves to remove cockroaches, without pollution!! As soon as I used it, the cockroaches never came again.

At night, drop dish soap in places where cockroaches often pass by and some die nearby in the morning. This one is safer, but it doesn't work very well.

Or use the following method to work well, but there is a little hidden danger to buy a box of Huali cockroach killer (it seems to be called Huali cockroach killing glue bait or something) It is sold in large supermarkets.

I've used it at home and it's very effective.

But this one is used to kill cockroaches by smoking.

Light the thing, close the doors and windows, and keep people, pets, etc. out of the house (and don't stay too far away from home to prevent accidents).

Then I came back a few hours later and saw that the cockroaches were dead, just sweep them clean, and then pay attention to open the windows to ventilate.

Cockroaches have flat, black-brown bodies, and are usually medium in size. The head is small and can move. The antennae are filamentous and the compound eyes are well developed. wings flat, forewings elytra, hindwings membranacean, anterior and posterior wings basically equal in size, covering the dorsal surface of the abdomen; Some species are wingless. Not good at flying, able to walk quickly.
