Cockroaches in Ellis County: American vs. German, and How to Keep Them Out
Seeing a roach scurry across the kitchen floor is nobody's favorite moment. The good news is that Texas A&M AgriLife has plenty of practical advice, and a few simple habits go a long way. Here is what Ellis County homeowners ask most.
Is one big roach in my house an infestation?
Not necessarily. Large roaches like the American cockroach live mostly outdoors and wander in looking for food or water. Texas A&M notes that sticky cards can help you see whether more are around and where they are coming in. One sign to watch for: if you see roaches during the day, it usually means there are a lot of them.
Why are there so many cockroaches in North Texas?
Our warm weather helps. Texas A&M lists American, German, oriental, and smokybrown cockroaches as the most common in Texas. Warmer temperatures speed up their development, and roaches gather near heat and moisture, which helps them grow and reproduce faster.
What's the difference between American and German cockroaches?
American cockroaches (often called "waterbugs" or "palmetto bugs") are the largest roach in Texas at 1½ to 2 inches, reddish brown, and both males and females can fly. They are common in sewers and live mostly outdoors.
German cockroaches are much smaller (½ to ⅝ inch), light brown with two dark stripes behind the head. They live indoors, breed fast (a generation in about 100 days), and are linked with allergies and asthma.
Do German cockroaches live outdoors in Texas?
No. Texas A&M says German cockroaches do not live outdoors in Texas. They spend their lives indoors, usually in warm cracks near food and water, like kitchens and bathrooms. Look-alikes such as the Asian and field cockroaches can be found outdoors in some areas.
How do roaches get in, and how do I keep them out?
Larger roaches often come in through poorly sealed doors, roof soffits, and floor drains. Texas A&M suggests:
Keep P-traps in drains filled with water.
Seal cracks of ⅛ inch or more in the foundation and exterior walls, and caulk around pipes, windows, doors, and A/C lines.
Keep door thresholds tight and screen roof soffits.
Keep firewood, lumber, cardboard, and yard debris away from the house.
Don't leave dishes, food, or pet food out overnight, and fix leaky faucets.
Why do I see more roaches after rain?
American cockroaches live mostly outdoors, in places like sewers, mulch, woodpiles, and underground water meters, and Texas A&M says they may move indoors in search of food or water. Keeping P-traps full, door thresholds tight, and soffits screened helps keep those visitors outside.
