Spiders are one of natures best pest control options. There are only a couple which are poisonous in our area though they are uncommon to encounter. Some spiders are web weavers, meaning they catch most, if not all, of their food via web - but some are hunters whom activity seek their prey.

Spider Groups

Group: Cellar Spiders

Cellar spiders are smaller (body is about 1/16 to 1/4") and dull in color with long slender legs. They may be confused with daddy-long-legs. Their webs are irregular and are constantly being added to. The female and male mate and share a web in a dark damp area such as crawlspaces, basements, and outbuildings. Their populations can grown quite high, though are not thought to be poisonous to humans.


Group: Cobweb Spiders

The web of the cobweb spider is irregular and contains an outer layer of sticky silk to catch prey. They will abandon their web when catching other insects proves unsuccessful, leaving their webs to build dust. Cobweb spiders do not deconstruct their webs prior to rebuilding a new one. Cobweb spiders will use their web as a safe, secure spot during the day and opts to build in a location that is moist, dark and undisturbed.


Group: Crab Spiders

These spiders resemble crabs, they can even walk sideways and backwards. They may have horns or other decorations. They are found in trees, on flowers, or hunting on the ground. These spiders ambush their prey, though their venom is not thought of as toxic to humans.


Group: Funnel Web Spiders

These spiders construct large, thick webs that are usually horizontal, flat and non-sticky. The web will often have a funnel which runs through it so the spider may escape if in danger. The spider will also use this funnel area of the web for hiding while it awaits prey to stumble across the web, causing vibrations which the spider feels and then can ambush the potential food source. These spiders are usually large and brown in color - their venom is usually nontoxic to humans.


Group: Jumping Spiders

Jumping spiders get their name because they jump to catch their prey. They are hairy and range in size from 1/8" to 3/4". Their legs as shorter then other spiders when compared to their body size and they often have areas of color on them. These spiders have great eye sight because they rely on catching their prey rather than the web catching the prey. They prefer to hunt during the day and are attracted to sunlight.

Group: Orb Weaving Spiders

These are the spiders that create well organized webs, circular in shape with the appearance of the silk spiraling from the center out, they will usually construct a new web daily (they will sometimes consume the previous web). The webs purpose is for catching prey that may get stuck on the sticky silks. These spiders are rarely dangerous, though will bite if provoked.


Group: Wolf Spiders

Wolf spiders are not aggressive, though their large size (over and inch) and quick speed often alarms people. These spiders are hunters and will chase after their prey. Although they would prefer to remain outside, they may occur inside if they are searching for prey. The female will carry her egg sac under her abdomen, once the eggs hatch the spiderlings will crawl onto their mothers back and remain there for a number of days before dispersing on their own. It is important to note that these spiders do not build webs and are active hunters, usually living out of ground burrows.
