Roaches don't knock. They climb in through the gaps you'd never think to check.
The American cockroach — the big reddish-brown one — slips in through drains, sewer pipes, and gaps under doors. Once inside, it triggers allergies and asthma and contaminates food-prep areas.
They're climbers by nature: walls, pipes, and foundations are highways into kitchens, bathrooms, and garages.
Cut them off at the perimeter. Nano Film creates an ultra-smooth band around the home that roaches can't climb past — stopping them before they find their way inside. Watch the proof: our American cockroach demo shows exactly what happens when a roach meets the film.
