1.The habits of bedbugs

Bedbugs are small insects that suck blood and metabolize a smelly fluid, so wherever they crawl, they leave a nasty smell. At the same time, the stink glands can also be used as a defensive weapon, and they can smoothly escape when they encounter enemies. Bedbugs are afraid of light and are usually active at night, sucking blood from humans while they sleep. However, they are very alert and flexible, and when sucking blood, if the body moves slightly, it terminates the blood and crawls away to hide. The nymphs and adults of bedbugs rely on blood to live, and the amount of blood can exceed 1-2 times of their body weight, and the bedbugs can mate and reproduce normally after sucking blood. Bedbug life history belongs to incomplete metamorphosis, the whole life goes through egg, nymphs, adult 3 stages. The development from egg to adult is mainly related to temperature; At the right temperature of around 35 ° C, bedbugs complete their entire life cycle in only about a month.
