Aerosol foggers or bombs are the most popular because they're so easy to use, but when dealing with brown recluse spiders, they really don't work that well. They only kill the spiders that come into direct contact with the spray; once the spray dries, the spiders are relatively unaffected.

Most brown recluse spider bites take about 3 weeks to heal. For those with more severe bites, the site of the wound starts to develop necrotic (dead) tissue called eschar.

Inspect and Clean: Inspect for brown recluse spiders and either vacuum them or spray them with a contact aerosol like Zenprox Aerosol or CB 80. Zenprox will quickly kill them and stay active for a period of time.

Occasionally, however, Brown Recluse bites can inflict significant or even life-threatening damage. Bites may cause severe pain, ulcers, fever, chills, nausea, joint pain, or even seizures. If you believe you've been bitten by a Brown Recluse spider, you should see a doctor ASAP.
