Current Pest Advisory for Commerce Center (August 2026)

As an entomologist, I'm flagging two pests that are especially active in Commerce Center right now: roof rats and German cockroaches. The hot, dry August weather (85°F average) drives roof rats to seek water and shelter, and our industrial landscape provides abundant harborage. The tilt-up concrete warehouses along Eastern Avenue and the 5/710 interchange have classic entry points—gaps under loading dock doors, worn weatherstripping, and utility penetrations—that allow rats to move from the storm drains and pallet stacks into buildings. Look for droppings near dock plates, gnaw marks on stored goods, and rub marks along walls. German cockroaches thrive in the heat, and the concrete floors and moisture from drainage basins near the warehouses create ideal conditions. They hide in cracks around equipment, cardboard boxes, and break rooms, and are often brought in via shipping pallets. Watch for small, dark specks (feces), egg cases, and a musty odor, especially in kitchens and storage areas. If you notice any of these signs, act quickly—these pests reproduce fast in our warm climate. Below are the top-rated Commerce exterminators who specialize in these specific seasonal threats.
