On todays visit, I treated the entire perimeter of apartment and the pipes leading up to tenants apartment in basement with a liquid application on interior. I applied gel bait to countertops, door hinges, cabinet hinges, stove and piping. I placed glue boards around apartment and also under and around kitchen appliances. I recommend lowering the heat if possible as it is very warm in there. The warmer you keep it, the more likelihood of roaches being able to rapidly breed and expand. Please allow 2 to 3 hour dry time and 10 to 14 days for treatment to reach full effect. Thank you for choosing Green Pest Solutions!
