If you see a cockroach in your home during the day, there is a good chance you will find more. Other than sightings, signs of a cockroach infestation are cockroach droppings, a musty or mildewy smell, cockroach egg casings, and a cockroach nest. A combination of droppings, eggs and large numbers of cockroaches mean a nest is near and infestation occurring.

Different species require different methods of eradication. The cost is determined by the species, the measures needed to control the roaches, and the size of the area that requires treatment. Treatment programs can vary from one time application to continual maintenance programs. Usually, the maintenance programs are your best value.

The first step exterminators will take is determining the species of roaches. After that, they will prevent the infestation from growing by determining the entry points and sealing them off. Finally, the exterminator will choose the best form of pest control based on the species and infestation, and implement it. Common forms of roach control are baits, traps, and pesticides.

Reinfestations can occur depending on the particular species involved and where your home is situated. American cockroaches, for example, can come back more readily due to their habitat outside of a home or structure. Regular exterior cockroach control, in addition to sealing outside cracks and holes in walls, can help limit such invasions.

The absolute best way to eradicate cockroaches from your home is pesticide applications. Baiting and trap systems are also effective, but come in second place to pesticides.
