I once hired Sears Once a Year Pest control and they came out and put a touch of gel in different location throughout the house. In about 2 weeks it was impossible to find a living roach in that house and it WAS SERIOUSLY INFESTED!!! The only problem was the 1500 dollars they charged. Do you have a product that will work that good and if so which one?
We have several different kinds of cockroach gel baits. The most popular baits that are used are Dupont Advion Roach Bait gel and Maxforce Magnum Roach Gel.
