I would go to the store and buy two tubes and give it a week. For under $20 I doubt you can do better. I've used many different products and pest companies as well and this stuff is great. You will need to re-apply. Since I live in the south these bugs live outside and travel from yard to yard at night. We tend to get reinfested in the cold weather as the roaches head into the warmth of the house. I'm going to treat outside my house and see how it helps. Mike
