Different Spiders and Their Dangers in Glendale

Spiders to Watch Out For in Glendale

The most dangerous spider found in Glendale is the black widow spider. Black widow spiders are identified by their jet black color, red hourglass marking, and long legs. They can typically be found in water meters, attic spaces, crawl spaces, and underneath porch decks. While black widows prefer to stay out of view, they are known to bite when stumbled upon or disturbed. Their venom contains a neurotoxin which can lead to sweating, nausea, and muscle spasms. Seek medical attention if you notice these symptoms and think you have been bitten by a black widow.

Brown widows are less dangerous but have been spreading across the region. Brown widows can be identified by their tan, brown, or grey bodies and yellow or orange hourglass. Their bite doesn’t produce as much venom as the black widow, but they can still lead to an unsettling experience. Brown widows can typically be found around children’s toys which are left outside, along trash bin lids, and underneath patio furniture.

Wolf spiders are another common spider found in Glendale. They are known to be active hunters that hunt their prey during the night instead of catching prey in webs. Wolf spiders typically enter homes at ground level, finding their way into attic spaces, wall voids, and areas where they can hide during the day. At night, they emerge and can sometimes be seen crawling along walls or ceilings. They are identified by their hairy bodies, dark stripes, and earth tones of brown, tan, or dark grey. Their bites can lead to mild swelling, redness, and itching, and occasionally a secondary infection which would require medical attention.

Conditions That Attract Spiders in Glendale, CA

The mature landscaping, established homes, and nearby canyons contribute to the presence of spiders in Glendale homes. As the outdoor temperatures reach high numbers, spiders seek indoor areas and cool spots to avoid the heat. This leads to an increase of spiders found in attic spaces, garages, and outdoor decks.

Because spiders follow their prey, there are certain pests which contribute to their presence, as well. Ants, gnats, and flies can be found entering homes during the warmer months, leading to an easy food source for spiders to catch. Outdoor porch lights act as a beacon for flying pests, which encourage spiders to build their nests and homes near these areas.

Limit spider access by trimming the areas around your yard which borders local parks or areas of dense vegetation in Glendale. These spots contribute to spider breeding areas and create a spider highway to your home and yard. Remove leaf litter and leftover brush where spiders can hide, and sweep your home regularly to clear out established spider webs. Consider switching to yellow bug lights to reduce the amount of flying insects found around the exterior of your home, and trim branches and vines to reduce easy access to foundations and rooftops.
