Brown Recluse Spider: A Venomous Pest
Brown Recluse Spiders are venomous and controlled with regular Pest Control services.
Brown Recluse spiders are also called “Fiddle-back” and “Violin” spiders because of the brown violin or fiddle shaped mark on the top of its head or “cephalothorax”. Brown Recluse spiders get their name from their color and reclusive habits.

Pest Control Tips
There are several things you can do, with your Pest Control Service, to help prevent Spider infestations:
- Eliminate debris around your home that may give spiders a place to keep an egg sack.
- Remove boxes, and paper collections, inside and outside of your home and garage/storage areas.
- Use Regular Pest Control service for Black Widows, and pests they prey on. (Black Widows love crickets!)
- Switch out exterior light bulbs to less BUG attractive Yellow Light Bulbs. {Regular lights at night attract bugs like crickets, and roaches, etc.}
- Lights attracting other bugs at night will also attract Black Widow spiders, because they are a food source.
Brown Recluse Habits/Habitats:
Brown Recluse feed on live small insects. Outside Brown Recluse are usually found: around rocks, utility boxes, wood piles, and bark. Inside homes they look for areas that are seldom disturbed, like: basements, crawl spaces, stored boxes, and attics. Eliminate these habitats to help control Brown Recluse Spiders with your Pest Control Service.

Brown Recluse Pest Control
In some parts of the US, Brown Recluse Spiders can totally take over a home – infesting from the crawl space to the attic! Pest Control experts have struggled with these extreme infestations, but new research have proven a pest control technique effective… Professional fumigation – as in tent and treat the entire house. {Typically these types of treatment are done to control specific termite species.}
Following application of chloropicrin, Vikane fumigant (99.8 percent sulfuryl fluoride) was introduced at a dose of 9.8 ounces per 1,000 ft3 for a 25-hour exposure with a target accumulated dosage of 117 ounce-hours per 1,000 ft3. The required dosage was based on the target pest and a soil temperature of 71°F for the crawlspace of the building. The fumigation was monitored using an RDA Fumiscope, made by Key Chemical and Equipment Company. The actual accumulated dosage was slightly more than 160 ounce-hours per 1,000 ft3, which translated into 1.7x the drywood termite dosage.
Spiders were checked for survival about 30 hours after the building was aerated using the California Aeration Plan and clearance testing was conducted. Of the 36 brown recluses exposed to sulfuryl fluoride, all 18 males and 13 of 18 females were dead with the remaining five females being moribund. These five were dead within a week.”
