Brown Recluse Spiders


There is a lot of fear associated with brown recluse spiders, because of the severity of their bites. While there is a certain level of healthy fear, a lot of the fear comes from misinformation. The distinct brown violin mark on their backs is the reason they are also called fiddle-back spiders. They build their webs close to the ground in dark, secluded areas. They only bite when they are threatened or disturbed. There are several symptoms associated with brown recluse spider bites. If you think you have been bitten, it is important to see a doctor, because the symptoms are also associated with other diseases. Then, call Nashville Pest Control to get rid of the spider.

Appearance and Life-cycle:

Brown recluse spiders are round and about 5/8 of an inch long. They can range from a light brown to a dark brown in color, and they have a dark brown violin shaped mark on their backs. Their abdomens and legs are one color, so if you see a spider with color variations, it is not a brown recluse. The younger spiders are a lighter color than the adult spider.

Females can produce 1-5 eggs sacs. Each egg sac contains 31-300 eggs which take about a month to hatch. It takes about a year for an egg to become an adult. The development is affected by things like food and weather conditions. They are capable of living for extended periods of time without food and water.

Habitat and Behavior:

Brown recluse spiders are mainly found in the south and Midwest. They build their webs in dark, sheltered locations. They can be found in homes, barns, and basements. Their webs are disorganized and near the ground. They can hide under furniture or in boxes. The more clutter there is in the home, the more places they can hide. They will also hide under wood and trash outside. They do not use their webs to catch prey, instead the go out and hunt.

Level of Danger:

Brown recluse spiders do have a fairly nasty bite, but they only bite when they are being threatened. The type and severity of the reaction depends on the location of the bite and how much venom is injected. The bite isn’t always initially painful and it takes a couple hours for symptoms to appear. Typically, there is redness and swelling. Then there might be a blister surrounded by a red ring which is surrounded by a white ring. A red, itchy rash may also appear after a couple days. Other symptoms include fever, convulsions, itching, nausea, and muscle pain.

Normally, bites will heal on their own, but in extreme cases the area around the bite can be infected and even cause cell death. If this is the case, the wound will be painful and become black. Left untreated, severe permanent damage can be possible.
If you think you have been bitten by a brown recluse, it is best to seek medical attention. Other medical conditions have similar symptoms.

Signs of Infestation:

The best sign of a brown recluse is an actual sighting of a brown recluse.


Brown recluse spiders only bite if they are disturbed, so to avoid bites, it is best to try to avoid places they might hide. For example, wearing an infested piece of clothing or reaching into a dark area where they might have built their web.
