These common invaders of homes can measure up to more than fifty millimeters or two inches long. The tropical species of cockroaches are typically larger than other kinds of species. Some cockroaches have wings but most are not able to fly for extended periods of time, and all have two antennae and six legs.

While many people assume that cockroach infestations occur because of a lack of cleanliness in the home or poor housekeeping, these insects can enter households by latching onto items brought into the home. Cockroaches can also enter homes through gaps and cracks in the exteriors of homes and also can enter via sewer pipes or drains.

People often blame a cockroach problem on poor housekeeping. While cleaning floors, kitchens, and bathrooms is useful and very important to reduce food sources used by cockroaches, they may get inside and cause an infestation for other reasons. These pests can hitch a ride on infested items brought inside, get indoors via cracks and gaps in the home’s exterior, enter through drains or sewer pipes and a few species of cockroaches can fly inside when attracted to lights.

In terms of how serious cockroach infestation can be, it is important to note that they are both common and difficult to get rid of. The main reasons these infestations are difficult to get rid of include the fact that they hide in an array of areas, reproduce quickly, and potentially could become pesticide resistant. These insects can transfer E. Coli or Salmonella to food and being exposed to dead cockroaches or their feces can cause asthma or allergies.
