1. Soak tobacco in water for 2 ~ 3 days, and scatter it where ants are infested. When ants smell smoke, they will avoid it. After a few days, the ants will gradually disappear.

2. Cut the bicycle inner tube or rubber gloves into a long rubber strip with a width of about 1cm, scorch the surface, fix it on the foot of the food cabinet, or nail it on the door frame or window frame, which can effectively repel ants.
