Had a problem inside the House with Spiders, Mosquitos, and Fly’s. Followed the instructions and closed all windows, sprayed every room for about 10 to 20 second. Left the house closed for 2 hours, -instructions 15 min. After the 2 hours there were still the houseflies, (Green/Black) a little disorientated but still flying. Another complains is the smell. It does smell strong and the product leaves a waxy subtends.
(Description: Because CB-80 Extra has no residual effect, there is no need to worry about insecticide buildup.) This statement is controversial; cleaned all the counters and furniture.
Would not use this product again inside the House.
I am battling drain flies. I have put gel in all of the drains for three days and have sprayed the entire house twice with this product. I still am seeing flies and decided to try contact kills on them. I spray them and they fly off.... am hopeful they are eventually dying. I saw one on a white door frame and sprayed it. This one did not fly off and instead stayed on the frame. I watched for 5 minutes and he was still crawling on the frame so I hit him with spray again. Another 5 minutes and he flew away. Not exactly an instant kill for such an expensive spray.
