Sanitation and exclusion are the first things required for this type of roach. If you eliminate food sources, moisture or their harborages, it will put such pressure on the roach population, leading to better results with your pest control measures.
​
Sanitation and Home Repairs:

​

• Caulk all penetrations through ground level walls.

• Remove rotting leaves from window wells and gutters.

• Stop water leaks, screen equipment overflow drains, and take overflow water away from buildings; keep drain traps full or capped.

• Store firewood as far away from the house as you can. If you can lift it off the ground, it will help eliminate harborage areas.

• Discard old boxes and piles of papers where roaches can hide.

• Use a tight fitting lid on your trash can.

• Move garbage cans out of preferred moist habitat.

• Clean kitchen appliances thoroughly to eliminate food sources.

• It is not wise to allow pet food to sit out overnight for indoor pets. For outdoor pets, pick up the food after they are finished eating.

• .Ventilate moist spaces

• Remove rotting leaves from window wells and gutters.

 

Exclusion:

Although the American roach has many places to habitat outside, it will enter if there is an entry point.

• Seal as many exterior cracks and holes as possible on the outside of the home

• Caulk all penetrations through ground level walls.Caulk and repair holes around doors, windows, water pipes and baseboards.

• Place mesh screens over windows, floor drains, and vents. Seal any cracks or holes leading indoors with caulk or other sealants.These places serve as roach locations.

• Make sure that doors and windows fit securely inside the frames, to eliminate entry.

 

Much of the discussion on where cockroaches will harbor was written particularly with the German cockroach in mind. This species is most commonly found near sources of food, water, and warmth. This is particularly true of the small nymphs. The larger nymphs and adult males are known to range more widely inside infested buildings. Adult females forage for food and water in a manner similar to the males, except during the few days before the egg capsule hatches. During this time they will forage very little.

When inspecting for  cockroaches, thoroughness is the golden rule. Check places such as cracks and crevices, under tops of tables, behind and under sinks, in cabinets, the motor compartments of refrigerators and soft drink dispensing machines, underneath the bases of kitchen equipment or pallets which are set on the floor, in switchboxes and fuse boxes, underneath cafeteria counters and soda fountains, in food carts, in cash registers and telephones, in vegetable bins, around meat counters and check-out stands, under meat cutting blocks, and almost anywhere else conditions are favorable. It is impossible to list all the places where cockroaches may live and hide, so you must inspect thoroughly and use judgment and roach "thinking" to find all of the harborages.
