I'm a clean freak but I guess it just can't be helped that sometimes, I will get roaches...I know that now since I live in an apartment and I know that roaches can travel in the walls. I was worried that I had to keep paying for an exterminator. I can't afford one and of course, I just didn't know what to do. Pest Mall helped me out a lot and was really patient with me. Alpine Gel Piston is super easy to use and it totally works!
