Spider Webs in Rialto & Fontana: What They Reveal About the Spiders in Your Home

Orb Weaver Spider web

If you’ve ever walked through your yard in Rialto or Fontana and suddenly felt a sticky thread across your face, you already know just how common spider webs are in Southern California. What most people don’t realize, though, is that the type of web you see can actually tell you a lot about the spider that made it. Some spiders weave neat, picture-perfect webs that look like they belong in a Halloween movie, while others spin messy tangles of silk that serve as a warning sign you may be dealing with something more dangerous, like a black widow.

One of the most familiar webs is the orb web, those large, round “wheel-shaped” webs that glisten in the morning dew. These are created by orb weaver spiders, which are harmless to humans and great at catching flying insects like gnats and mosquitoes. On the other hand, if you notice a web that looks chaotic and sticky, clumped together in a dark corner of your garage, under patio furniture, or tucked into a shed, you’re probably looking at what’s called a tangle web. This messy design is typical of cobweb spiders, including the infamous black widow. Unlike orb weavers, widows are venomous and can be dangerous if disturbed, which makes spotting their webs especially important.

Some webs look entirely different—like funnels or blankets. Funnel webs, for example, resemble a sheet of silk that narrows into a tunnel. These are made by funnel weaver spiders, which aren’t usually dangerous but can be startling when they dart out to catch prey. Sheet webs, on the other hand, look like thin, flat blankets stretched across grass or shrubs. The spiders hide beneath the silk and wait for insects to stumble in. While these spiders aren’t harmful, their webs can make landscaping look messy and unkempt.

No matter which type of web you’re dealing with, the bigger concern is what it means for your home. Webs aren’t just unsightly—they can also signal the presence of venomous spiders, especially black widows and brown widows, both of which are common in the Rialto and Fontana area. Even if the spiders themselves aren’t dangerous, webs collect dust, allergens, and insect debris, making your home feel less clean and inviting.
