Why Altadena's Mild Climate Creates Year-Round Spider Problems

Two Spiders to Watch Out For in Altadena

Most Altadena residents have a love-hate relationship with spiders. Spiders are beneficial for natural pest control as they hunt insects and pests for their meals. Outdoor porch lights draw in flying pests, acting as a beacon of light that lures them in. As nightfall commences and insects migrate towards the exterior of homes, their activity attracts spiders to build webs along rooflines, patio eaves, and around garages. 

Brown widows in Altadena prefer these outdoor spaces and tend to build webs under patio furniture, along trash bin lids, and even beneath toys left outdoors. Identified by their tan, brown, or grey bodies, these spiders do have an hourglass identifier which is typical orange or yellow. Their bite doesn’t produce as much venom as a black widow, but their presence is still unsettling nonetheless.

Black widows are identified by their jet black color, long legs, and red hourglass marking, and can be found inside water meters, in attic spaces, and underneath porch decks. While black widows do not actively hunt humans, they will bite when they are startled. Their venom contains a neurotoxin which can lead to nausea, sweating, and muscle spasms. If you notice these symptoms and think you have been bitten by a black widow, it’s important to seek medical attention.

Conditions That Attract Spiders in Altadena, CA

The established homes and mature landscaping in Altadena contributes to the presence of spiders in homes. The lack of harsh winters allows their population to grow exponentially, and the abundant presence of insects creates the perfect feast.

Spiders are predators. They are not focused on food and moisture like ants, or finding nesting areas like rodents, they simply follow their prey and set up a web nearby. Ants, flies, and other flying insects come into Altadena homes through cracks in foundations, underneath worn door sweeps, and doors left open on hot summer days. This trail of insects attracts spiders and leads them to set up shop in areas where their webs are the least likely to be disturbed.

In order to limit spider access, trim areas around the barrier of your property that border dense vegetation or spider breeding areas. Remove leftover brush and leaf litter which provide hiding spaces, and regularly sweep for established spider webs. Consider using yellow bug lights to limit insect crowding around the exterior of your home, and trim branches and vines which provide easy access to foundations of rooftops.
