House pests are a common problem for many homeowners. Roaches (5 letters) and ants (3 letters) are two of the most common house pests. Roaches are small, brown insects that can be found in kitchens and bathrooms. They are difficult to get rid of and can spread disease. Ants are also small, but they are usually black or red and can be found in many areas of the home. They can be a nuisance, as they often build nests in walls and other areas of the home. Both roaches and ants can be controlled with proper pest control measures.
