Spider Extermination and Control (North America): All spiders encountered in North American yards, forests, trees, and landscaping make their living preying on insects. Most of the insects that spiders prey on are harmful to us, our grasses, shrubs, trees, and gardens. Without spiders, therefore, we would be overrun with insects and our lives would be much less enjoyable.

Since spiders are such beneficial organisms, rather than taking steps to exterminate them, we should instead do our best to keep them alive. Still, two kinds of spiders--black widows and recluse spiders--pose a clear danger to man and should be exterminated in or on residential or commercial structures, or in barns used to house cows, horses or sheep, whenever they are found. Others need to be controlled because their habits make them problematic in unusual ways. Under those circumstances, it may be best to spider-proof the areas we want to keep spiders out of, and exterminate those that outwit our spider-proofing endeavors.

FIRST THE BAD NEWS: Traditional residual pesticides, in the form of sprays, dusts, or granular baits, are not effective at exterminating spiders unless brought into direct contact with them. Spiders hunt live prey exclusively and show no interest in inert baits.  Further, a spider's body mass is elevated, so only the tips of each leg--the miniscule tarsus--touches the ground or the spider's web, where residual pesticides might otherwise intoxicate them.
