Pest Description

Sac Spider Behavior

Spiders are arachnids, though they are sometimes confused for insects. Although they are often found on plants, they mainly consume insects and other spiders, not plant material. Most spiders kill their prey with a combination of binding and toxic venom. The only spiders considered “poisonous” are those which can bite and cause serious physical reactions in humans.

Problems Caused by Sac Spiders

Spiders are considered beneficial animals because they are predators of harmful insects and other arthropods, but spiders can still be considered pests due to their bites. As spiders move around in buildings and other human dwellings, they may bite if threatened, crushed, or otherwise disturbed. This concerns a lot of people, as the physical and psychological effects of spiders and their bites can be upsetting. In an ideal world, spiders would be beneficial outdoors, and non-existent indoors.

Preventing Sac Spiders

Proper cleaning of the building environment can significantly reduce the chance of an unnoticed sac spider issue. Reducing clutter and debris in parts of the building that go unused are all part of the basic prevention method. Outdoors, proper lawn maintenance should be observed. Any cracks, holes, or entry points in the building should be properly sealed as well.

Controlling and Eliminating Sac Spiders

Spiders can become serious pests if allowed to infest a building or home. Exposure to spider bites may be harmful to some individuals sensitive to their venom. A trained pest management professional should always be called in circumstances involving infestation. Comprehensive spider service includes three steps: Inspection, Treatment, and Follow-up. A thorough inspection should always be completed to determine sources of infestation, possible entry points, and the identification of the spider itself. There are various methods of treatment for spider infestations, including treatments of the baseboards, windows and doors, and foundation structures. Treatment will reduce populations outside, and eliminate populations inside. A good pest control professional will always provide follow-up after treatment, ensuring a successful elimination of the infestation. Continual treatments are also recommended to ensure a building is spider-free.
