Cockroaches can also trigger allergic reactions in some people. Except for size and markings, all cockroaches have a similar appearance. These insects are dark in color, oval-shaped, and have long antennae. Roaches are mainly active at night and generally remain hidden during the day in cracks and crevices near their source of food. Use nontoxic sticky traps to locate roach habitat.
Roaches like to travel by touching the edges of objects.
Place traps along the edges of walls, appliances, cupboards, etc., and not in the middle of the room. When you find out where roaches are hiding, you'll know where to concentrate your efforts. Less-Toxic Controls Use sticky traps for small infestations. If you only have a few roaches, you may be able to control the problem with sticky traps. Use a strong vacuum with a crevice attachment to pull roaches from their hiding places.
