- Make sure windows and doorways are sealed properly with stripping or caulk where necessary, to prevent entry.
- Reduce clutter in rooms, closets, garages, attics to prevent areas of nesting.
- Outdoors keep patios and porches clean & washed regularly. Clear webs from around doors, windows and eaves.

There are a lot of people who think they have been bitten by a recluse or think they know someone that was bitten by a recluse but most of the time these are infections caused by something other than a spider. There are actually very few confirmed recluse bites in South Carolina. Many people believe they have seen the poisonous brown recluse on their property however, in the last ten years, all the spiders thought to be a brown recluse, submitted to Clemson University Entomology Department actually were not.
