Talstar P is the best stuff I've found. I've been using it for the last two or three years primarily for ant and spider control. I buy the 3/4 gallon size since it has a shelf life of three years. You only use 1/2 to 1 oz. per gallon of water so it's a much better value than the less effective stuff you buy at the big-box stores. I use a 4-gallon backpack sprayer. I only have to apply it two or three times per year...results last for months. It's pet and child safe after it dries. The site I linked has excellent tutorials for insect control. The first time I purchased, I got it from Amazon for the same price listed on the linked site.
