1. Inside high-rise buildings: Ants like to move in low altitude, humid and warm environment. High-rise buildings are usually dry and have good airflow, so it is difficult to become a habitat for ants.

2. Poor areas: Poor areas lack enough food, water and habitat, so it will be difficult for ants to survive in such an environment.

3. Closed environment: In closed environments such as laboratories and factory workshops, ants can be prevented from entering by physical measures (such as closing doors and windows, sticking anti-ant tapes, etc.). ).
