The present invention relates to the technical field of pest control, and particularly relates to an insect trap.
Bedbugs, small nocturnal insects of Cimicidae family, live on blood of humans and other warm-blooded hosts. Detection and control of the bedbugs are extremely difficult and time-consuming due to their mysterious behaviors. It is particularly so for common bedbugs (i.e., Cimex lectularius) which have greatly adapted to the human environment. Other types of bedbugs, for example, Cimex hemipterus cause nuisance to people and/or animals as well. Although bedbugs have been under control in many countries and regions, such as the United States of America, they resurge as a result of explosion of tourism around the world in recent years. What's worse, dependent on their intrinsic features, bedbugs will be difficult to eradicate once found in some place. Thus, an effective insect killer, which may position and kill the bedbugs effectively before they are out of control is urgently needed.
An insect trap generally comprises a trap and a trapping box. In the prior art, the trapping box of the insect trap is often mounted at the inner side of the trap, a through hole for the insects to climb into the trap is formed in the shell of the trap; or the outer side wall of the trapping box is connected to the outer side wall of the trap.
