First, spray pesticides. Its advantages are simple operation, convenient use, quick effect, and the cockroach will die immediately after spraying. However, this medicine will only die if sprayed on cockroaches, and the sprayed medicine will soon evaporate and fail, so the invisible cockroaches can't be killed, so cockroaches can't be completely eliminated. In addition, the sprayed cockroaches are also resistant to small cockroaches and cannot be killed.
Second, insecticidal powder. This medicine is in powder form and easy to take. Just sprinkle it directly. The cockroach took the medicine and died slowly. Cockroaches will eat powder medicine at first, but after a while they stop taking medicine, so they can't kill cockroaches. Moreover, when used in wet and watery places, drugs are easy to fail.
Third, the glue bait to kill cockroaches. The gel bait for killing cockroaches is a relatively new drug, which should have the best cockroach killing effect at present. For example, this medicine, such as the cockroach-killing gel bait in Jie Bing, is in paste form. The medicine is packed in a needle tube, and an attractant for attracting cockroaches is added to the medicine, so that cockroaches can be induced to take the medicine actively. Cockroaches will die slowly after taking medicine, and live cockroaches will eat dead cockroaches and die slowly. Through the mutual infection between cockroaches, the effect of chain cockroach killing can be achieved, and cockroaches can be completely eliminated only once. At present, the gel bait for killing cockroaches by cleaning soldiers has the best cockroach killing effect. Try to choose some regular manufacturers when you choose, and generally you can achieve good results.
