Find a beer bottle, put some sesame oil (no sesame oil, cooking oil is ok) in it, rotate the bottle body to make its inner wall have oil stains, then coat a little sugar on the inner wall of the bottle mouth and bottle handle, and finally put the bottle in a place frequented by Xiao Qiang. Xiao Qiang will steal sugar along the bottle mouth at night, and finally he will fall into a trap. Because there is oil in the bottle, he can't climb up any more, so he can put as much as he can. Ha, I'm trapped by you. You can do whatever you want. So many times. Xiao Qiang naturally disappeared.

After observing the main passage frequented by cockroaches, sprinkle egg shell powder here, and cockroaches can avoid it when they smell it. (2) Boric acid cockroach killing method. Take proper amount of flour, boric acid, onion and milk, chop the onion first, and then squeeze it into juice. Add onion juice to the mixture of flour and boric acid, add a little milk, knead into balls with the diameter of 1 cm by hand, and put the balls of boric acid in places where cockroaches often haunt. Because cockroaches have a special preference for the smell of onions, they can eat meatballs as soon as they come up, but once they eat them, boric acid will dehydrate them and die;

At present, several methods of killing are:

(1) scald, burn and clear oocysts. Clean cockroaches in stoves, cupboards and drawers in combination with hygiene, and scald or burn their oocysts with boiling water. This is a common method to kill cockroaches, which has a certain effect on reducing cockroach density and reducing its harm.

(2) Trapping method: Use wooden box traps, the size of wooden boxes is 14.5 * 10.5 * 5cm, with holes of 3.5 * 2.5cm on both sides, and each box is equipped with an anti-flooding funnel made of cardboard. Put a little pasta that cockroaches like to eat as bait in the wooden box, such as fresh toast and steamed bread, at a price of 65430 per night.

(3) Drug killing: fumigation with dichlorvos smoke, closing doors and windows and sealing the environment before fumigation can achieve certain results. 20% trichlorfon powder is used in places where cockroaches often move, and the killing effect is also good when sprinkled on it. The mixed application of dichlorophenyl ether ester and dichlorvos also has a good fumigation and insecticidal effect. Spraying with propoxur diluent has the best killing effect on cockroaches.

(4) Poison bait method: 2% trichlorfon or dichlorvos liquid medicine is mixed in crushed steamed bread and other foods according to the ratio of 1: 3, which can kill cockroaches when used at night. Or use cockroach chips sold in the market and put them in places where cockroaches often move, which also has a certain poisoning effect.

In addition, according to the cockroach's habit of eating paste, 2% phoxim or 2% acephate and other drugs are mixed in the paste, and then applied or sprayed in the place where cockroaches live and go out, which can obtain good insecticidal effect.

When using drugs to kill cockroaches, we should pay attention to the kitchen bowls, chopping boards, pools, walls, roots, and indoor bookcases, cabinets, drawers, floor cracks and so on. When using drugs, we should pay special attention to prevent food and cooking utensils from being contaminated and prevent poisoning incidents.
