Cockroaches
The Most commonly occuring Cockroach species in Pennsylvania are: German Cockroaches, American Cockroaches, Oriental Cockroaches, Brown-Banded Cockroaches and Wood Cockroaches.
Cockroaches are nocturnal so if there is a daylight sighting, it is likely there is an infestation. Other signs of a cockroach infestation include: droppings, egg casings, smear marks, damage to food containers or surfaces and furniture (leather, fabric) and/or a foul odor.
Cockroaches can be difficult to control and eliminate! They reproduce quickly and can survive for long periods without food or water so if you suspect that you have Roaches then call SWAT immediately.
