Don’t Count on Sprays

All the chemical products in the world will not be effective in eliminating a spider population. Spiders are able to stay safe from pesticides because of their proportionately long legs. Since they do not pick up the pesticides as much as other insects, you cannot rely on spraying these critters to kingdom come.  That and the fact that they don’t have a system with blood flow means the pesticides cannot travel to the rest of their bodies.
