Irvine Property Owners’ Handy Spider Prevention Guide
Here in Irvine, California, we enjoy one of the best lifestyles in the whole country. We’re surrounded by amazing parks and wilderness areas like Crystal Cove State Park and Limestone Canyon Regional Park, and we’re just a short drive away from some of the best beaches and fine dining options Southern California has to offer.
However, there’s always a price to pay for proximity to amazing outdoor lifestyle locations, and for us, that price includes lots of spiders. Spiders are everywhere here in Southern California because we have year-round mild weather and plenty of insect prey to feast on.
Common Spider Species
Luckily for us, most of the spiders that live here in Irvine are harmless to humans. These species include:
- Southern House Spiders: Commonly found in cracks and crevices in your home. They’re large, brown, and harmful only to insects.
- American House Spiders: Responsible for lots and lots of cobwebs, these little brown arachnids have spindly legs and big bodies. They can often be found in the corners of your home, weaving their webs between the walls and ceiling.
- Domestic House Spiders: These spiders are globally ubiquitous and also completely harmless. They’re normally rust-colored with dark rings around their legs.
Unfortunately, while the majority of the spiders that inhabit our area are benign, there are a couple of more dangerous varieties to watch out for:
- Black Widow Spiders: These spiders live throughout much of North America. They’re most famous for their shiny black color, the bright red hourglass on their abdomen, and the myth about a female's tendency to eat their mates. The good news is that bites from a black widow almost never result in death in adult humans. The bad news is that they can pose a serious threat to children and pets, leading to acute illness and sometimes hospitalization.
- Brown Recluse Spiders: Although it’s rare to see these spiders in California, it’s not out of the question to spot one on occasion. They’re brown, long-legged, and have a fiddle-shaped mark on their cephalothorax. These spiders also don’t normally pose a serious threat to human life. However, they pack a powerful hemotoxic venom in their bites that can cause necrosis if left untreated. While this necrosis isn’t normally fatal, it can cause infection and lead to tissue loss and scarring.
- Yellow Sac Spiders: One of the most common spiders in Southern California, these fearless, aggressive arachnids are famous for invading homes and inflicting bites on humans. These bites are often painful and can, in some rare cases, cause systemic symptoms like fever, fatigue, nausea, and muscle cramps. These spiders are usually yellow or light brown with front legs longer than all the others.
Ship The Spiders Out
Unlike most other pests, spiders have no real reason to enter our homes unless they’re already infested with their natural food sources. Usually, whatever spiders you’re running across in your house are there to chase common prey items like flies, roaches, millipedes, and silverfish.
The best way to prevent spiders is to prevent other insect pests through measures like:
- Clearing clutter to eliminate hiding places for creepy crawlies.
- Drying excess moisture to reduce insect water sources.
- Storing food and trash properly and keeping it tightly covered to prevent odors.
- Fixing torn window screens to keep flies out.
There are also a few spider-specific prevention methods you can employ, such as:
- Sweeping away cobwebs to discourage spiders from taking up residence.
- Storing wood off the ground and away from the exterior walls of your home.
- Trimming bushes and trees away from your house.
- Dusting house plants for spiders hiding in their foliage.
- Sealing up entry points like loose window screens, gaps in door sweeps, cracks in your home’s foundation or siding, and ventilation/condensation outlets (seal these with metal screens to allow for air or water flow).
Unfortunately, even the most stringent pest prevention measures can’t always stop determined insects or the spiders stalking them.
