Spiders aren’t insects they are Araneae .Spiders can be difficult to control with just a pesticide application alone. A pesticide application affects spiders in two ways .First if a spider comes in direct contact with the pesticide it will die. An additional benefit from a pest control service is that it also eliminates insects spiders eat such as ants,crickets,earwigs and other broad spectrum of pests.

Due to the diminished insect population Residual spiders will web in open areas. This may last a few weeks after your pest control service. Eventually the spiders will be eliminated by starvation or from pesticide contact. For more info about spider control visit our pest library or fell free to give us a call.
