The parson spider is a nuisance in homes and is generally nontoxic; although some people may experience allergic reactions to the bites. The front segment of the body tends to be a chestnut color, while the abdomen is grayish with a distinctive white or pink pattern along its middle. The body is covered with fine hairs, giving a velvety appearance. The parson spider is usually found outdoors under rocks or in piles of brush or firewood. This spider does not spin a web, but wanders on the ground in search of prey.

Indoors, this spider wanders about at night and conceals itself beneath objects or in clothing during the day. Most bites from this spider occur at night or when it is trapped in clothing. While the parson spider is not considered poisonous, bite symptoms are variable in severity. Some people may experience localized allergic swelling and itching in addition to initial pain. A few persons may experience excessive swelling, nervousness, nausea, sweating and elevated temperatures from the bites.

Prevention:

The best approach for controlling spiders is through placement of sticky traps to capture a few spiders that may have entered. Maintaining sticky traps behind furniture, to either side of exterior doors, and in the garage is an excellent way to intercept most spiders as they enter.

Install tight-fitting screens on doors and windows to prevent entry.
Seal or caulk cracks and crevices where spiders can enter the house.
Install yellow or sodium vapor light bulbs outdoors since these attract fewer insects for spiders to feed upon.
Be sure to dust and vacuum frequently around windows, corners of rooms, shelves, under furniture, and behind mirrors and pictures.
If you see spider egg sacs, remove them.
