Cockroaches, commonly known as cockroaches, are common medical insects, belonging to Arthropoda, Insecta and Cockroaches. Only dozens of species will invade people's homes, and several species will be kept as pets and become food for pets. Most of them can only be seen in barren hills and wild forests or insect museums.

Habits of fleas: the habitat of fleas depends on the habits of hosts and the influence of external factors. For example, the larvae of the pioneer fleas parasitic on mice are mostly born in mouse nests, while the larvae of human fleas are mostly born in bed boards, bedding, walls and animal poles. For different flea species, the habitat habits of adults are different, including common flea type and nest flea type.

Hairy fleas mostly live in the host cluster, suck blood frequently but have poor hunger tolerance, and require high temperature, such as pioneer fleas, dog fleas, cat fleas and so on. The flea-collecting type is mostly parasitic in the nest of the host, with less blood-sucking times, strong hunger tolerance and low temperature requirements. There are often a lot of fleas in the nest, and most of the fleas parasitic on wild rats belong to this type.

Adult fleas can eat nothing for 12 months, and get nutrition by sucking blood whenever possible. Because fleas have no specific host, they can parasitize all kinds of hairy animals, even hairy inanimate objects (such as carpets). Therefore, only controlling fleas on pets cannot eliminate fleas.
