How to deal with tiny bugs under the bed when the weather is dry and humid?

Spray radar or gunmen to kill insects first. If you can't kill the bugs, go to the epidemic prevention station to buy special pesticides for spraying. Clean up after pest control, take the mat on the bed to the outdoor sun, pat it for dehumidification and pest control, and then dehumidify the bed with quicklime. Usually keep the room ventilated and dry, and often clean the bed, so that bugs will not regenerate.
