Jumping Spider Control in New Jersey, New York City, Philadelphia, Connecticut, and Delaware

Appearance

What Do Jumping Spiders Look Like?
Size: The daring jumping spider, one of the largest species of jumping spiders, grows to about 3/4 of an inch long, while the smallest jumping spiders measure 3/20 of an inch in length.

Color: While some jumping spiders are brightly colored, most have dull, earthy colorations perfect for camouflage.

Characteristics: Jumping spiders have superb agility and sharp vision. Jumping spiders have a very distinctive eye arrangement. Four larger eyes face directly forward on the front of their cephalothorax, while two rows of four smaller eyes rest more dorsally on top. The arachnid’s vision is reportedly one of the best among arthropods and allows the pests to see a broad spectrum of color and detail.

Facts

  • Distinct: Jumping spiders are distinctive in both appearance and in their lightning-quick movements, which allow the predators to stalk and pounce on unsuspecting prey.
  • Problems: They are mostly beneficial as they keep populations of insect pests in check and shy away from human contact. Still, individuals who fear spiders generally benefit from avoiding these arachnids.

Food

What Do Jumping Spiders Eat?
Jumping spiders can eat prey twice their size thanks to their potent venom, which easily subdues oversized targets. Some of the arachnids maintain vegetarian diets by eating nectar instead of insects, which is unique to the species.

More commonly, though, they consume insects, like:

Biology

Mating
In order to court females, male jumping spiders perform dance-like rituals. Two males sometimes vie for the same mate, which typically results in the larger individual coming out victorious.

Life Cycle
Females construct nests to house fertilized eggs. Upon hatching, the young spiders resemble miniature adults and reach adulthood through a process of several molts. Once adults, the spiders can jump as far as 20 times their body length to escape danger.

Detection

  • Sight: May notice adult spiders during daylight hours.
  • Hiding: Be alert for jumping spiders in gardens, attics, basements, garages, and along the side of buildings.
  • Webs: Look for webs, which are only built to house egg sacs.

Problems Caused by Jumping Spiders

Bites
Although jumping spiders do not typically bite, incidents have been reported. The arachnids are not a medically important species; however, individuals with severe allergies experience elevated risks and should seek medical attention if such contact occurs.

Generally, the most severe bites cause symptoms similar to those experienced after bee stings.

Signs of Infestation

The most direct way to diagnose infestations is to spot adults. In contrast to most spiders, which are nocturnal, jumping spiders are diurnal in nature and often cross paths with humans.

Additionally, as the pests use their silk to house eggs and to occasionally assist with movement, individuals may find strings or web-like structures around the home when jumping spiders are present.

Prevention Tips

Seal Cracks & Holes
Find all the holes and cracks in building foundations in order to seal possible points of entry and reduce the possibility of jumping spider infestation.

Habitat Modification
Individuals should also practice habitat modification to limit potential food sources in and around buildings. Such techniques require maintaining a debris free landscape and leaving exterior lights off in the evening to lessen the attraction of readily available food sources near the home.

Tips for Removal from Home

Catch & Release
Removal can be as simple as capturing a single spider and releasing it outside.

Seek a Professional
More extreme methods are needed when large numbers of the pest are present. Enlist pest control professionals as soon as jumping spider problems become too much to handle.
