There are approximately 35,000 species worldwide with 3,000 occurring in North America.  Many species are considered household pests and occur wherever food is available.  Spiders are predators feeding mainly on insects and other arthropods.  There are only two groups of spiders in the U.S. that are considered dangerous to humans:  Black Widow and Brown Recluse Spiders.  There are several species in each group.

Several steps are needed to obtain proper control.  First, inspection of the building is essential in finding the spiders, harborage (nesting sites) and their food source.  Next, proper identification is needed for pest management and medical reasons.  Once the first two steps are accomplished, we will develop a pest management plan.  This plan will consist of mechanical measures and pesticide application.  Mechanical measures consist of physically removing the spiders, egg sacs and their food sources with a vacuum, broom or other device.  Pesticide application will be determined based on the location and surrounding environment.  This could include spot and/or space treatments as well as perimeter treatments. 

After the pest management plan is complete measures need to be taken in order to prevent the re-infestation of the spiders.  Prevention consists of making sure the building is in good physical condition (properly screened and sealed to reduce entry), removing the food source by redirecting the lights to shine off the building and changing the lights bulbs to make them less attractive to insects.  Our trained pest management professionals will identify these solutions and others.
