False Black Widows

Genus: Steatoda

Actual Size and Characteristics: There are over 120 species that could be identified as false black widows. They are typically deep brown, deep plum, or black. They lack the same distinct hourglass marking that many black widows have, though false widows often have white, beige, or red spots.

Behavior:

  • While some species have medically-significant bites, most false widow bites produce very mild symptoms in humans.
  • False black widows are generally non-aggressive. Most humans are bitten after squeezing or pinching a widow spider.
  • They weave tangled, messy webs.
  • False black widows, like their venomous counterparts, prefer to nest in dark and undisturbed areas.

Pest Description

False Black Widow 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.

Preventing Problems Caused by False Black Widow Spiders

Despite the fact that they rarely bite humans, false black widow spiders can still be unsettling. Their webs are more of an issue than their bite. In an ideal world, spiders would be beneficial outdoors, and non-existent indoors. Proper cleaning of the building environment can significantly reduce the chance of an unnoticed false black widow 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 False Black Widow 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. At Pest Control Inc., our pest control experts resolve spider issues using a variety of different treatment techniques including surveillance, removal, dust, and liquid applications.
