Most types of spiders are harmless and don’t pose a huge threat to humans. However, there are two particularly dangerous types of spiders in Iowa: the black widow and the brown recluse. Both of these spiders are known to bite in defense, and their bites have been known to cause serious symptoms. For that reason, it’s smart to familiarize yourself with what these spiders look like along with their behaviors and habitats.
Although bites from brown recluses and black widows are rare, you can protect yourself by learning what to expect when you come across these eight-legged creatures.
Identifying brown recluse spiders
Brown recluse spiders are infamous for being one of the most dangerous spiders in the nation. Some of the things that help identify these spiders include:
- They are most commonly a dullish brown color and have a characteristic violin-shaped mark on their cephalothorax.
- An adult brown recluse can grow up to 11 mm in length, meaning they’re approximately the size of a quarter.
- Brown recluses aren’t typically aggressive and will try to avoid contact with humans unless directly threatened, which is when they may bite.
- Symptoms from a bite are usually mild, but serious cases may result in blisters, pain, and even necrosis.
