I liked CB-80 Extra but decided to give the 565 a try because it seemed to be a better deal for essentially the same product. Wrong ! I only used one quick burst in my foyer--it stunk to high heaven and even worse left a sticky residue on my nice hardwood floors. I'm going back to the CB-80. The smell is not that bad or persistent and it leaves no residue. Note that this class of insecticide is not persistent i.e. it doesn't keep working long. I'd try the indoor Talstar because the outdoor works good but I can't waste any more money on bad choices.
