Preventing Spiders in Your Home

Nothing evokes that creepy crawly feeling quite like finding an unexpected spider in your home. But as creepy as they might look, not all of them pose a threat. In the United States, there are a wide variety of spider species, and understanding which ones are potentially dangerous and how to prevent them from invading your home is crucial to the safety and wellbeing of you and your family.

Here is a guide to common spiders you might encounter with insight into which ones can be harmful as well as practical tips for keeping your home spider-free.

Common Spiders in the United States

  • Brown Recluse Spider

The brown recluse spider does administer a venomous bite, but 90% of them result in no reaction or a small red lesion that usually heals on its own. These spiders can be identified by the distinctive violin-shaped mark on their body. They are commonly found in the Midwest and Southern states.

  • Black Widow Spider

This is a fairly easy one. The black widow spider is very distinct with a shiny black body with a distinctive red hourglass mark on the abdomen. Although they administer a venomous bite, fatalities are rare. Symptoms usually include painful swelling at the bite site, cramps, achiness, and nausea that subside within 12 hours. Black widows are found throughout the United States.

  • Hobo Spider

Hobo spiders are brown and build very unique funnel-shaped webs that are open at both ends. They are often confused with other spiders such as the brown recluse, so information about their bites isn’t clear although it’s believed that their bites are non-threatening, causing only mild pain and redness. Hobo spiders are found in the Pacific Northwest region.

  • Wolf Spider

Wolf spiders are also confused with the brown recluse spider. They do not spin webs and are excellent hunters. A wolf spider will only bite when threatened. It is non-venomous and usually harmless. They can be found across the country as most are nomadic wanderers.

  • House Spider

House spiders are the typical spider you see in your home. They are commonly found indoors, weaving webs in corners. Although house spiders can bite, these bites are not dangerous to humans. They may leave some redness and irritation at the bite area.

Most spiders you encounter in your home are harmless. In fact, they help control other pests by preying on insects. However, it's crucial to be cautious around spiders that are known to be venomous, like the brown recluse and black widow.
