If there are cockroaches in the car, it is necessary to clean the objects in the car in time, such as mats, spray medicine in the car, including every gap, and then keep it closed for half an hour. After the sealing is completed, open the vehicle for comprehensive cleaning. One day exposure in the sun can kill cockroaches. Cockroaches are afraid of light. The main reason is that this small animal has no eyes and can only sense the surroundings through touch. If the light is bright, it seems dull.
Physical control method for killing cockroaches
Cockroaches generally have no resistance to heat. When the temperature exceeds 60 degrees, they will die immediately and can kill eggs. All these cockroaches will freeze to death in the environment of minus 5 ℃ to minus 10 ℃ for about 30 minutes. The common method is to put boiling water directly into a kettle and pour it in the place where cockroaches often appear. You can also use a hair dryer to burn cockroaches in a few seconds.
Trapping, chemical control and biological control have certain effects. For example, add garlic leaves into water and spray them directly into a spray bottle. The cockroaches will die in about 20 seconds. Biological control is a common method at present, but some high-quality products must be selected.
Tips for dropping cockroach poison bait
Some people say that it is easier to put some cockroach medicine directly, but there will be some tricks here. First, it needs to keep the characteristics of small amount and wide range. It means that a lot of poison should be put in a small space, and the amount of medicine used at each point can be appropriately less. These cockroaches can take medicine immediately after climbing out of the resting place, which has a significant killing effect. In order to prevent the medicine from losing efficacy due to moisture, it can be placed inside the bottle cap and directly painted on the place where cockroaches often appear with chalk containing insecticide. Even if accidentally touched, the ash powder will be poisoned, but it should not be too thin when sliding. At least about two to three centimeters can be turned into a well shape, leaving cockroaches nowhere to escape.
