Brown Widow Spiders in Rialto & Fontana: Where They Hide and How to Treat Them

If you’ve noticed a strange-looking spider with a tan or brown body and an orange hourglass marking, you may have met the brown widow spider. While not as infamous as their cousin, the black widow, these pests are still unwelcome around your home and can cause painful bites if disturbed. At TruPest Solutions, we help Rialto and Fontana homeowners locate, treat, and prevent brown widow infestations before they become a bigger problem.

How to Identify a Brown Widow Spider

Brown widows are typically light brown to gray in color, with distinctive geometric patterns on their abdomen and a bright orange or yellow hourglass shape on the underside. They are slightly smaller than black widows but still prefer hidden, sheltered areas close to where people live.

Where Brown Widow Spiders Like to Hide

One of the biggest challenges with brown widow control is that they love tight, undisturbed spaces where you’re least likely to notice them. Common hiding spots around Rialto and Fontana homes include:

• Under patio furniture, especially in the corners of chairs and tables

• Inside outdoor storage boxes or sheds

• Under eaves, around light fixtures, and inside mailboxes

• In cluttered garages or tool areas

• Beneath children’s outdoor toys or play structures

• Around window shutters and door frames

Brown widows tend to stay near low-traffic areas, but they often build their messy, irregular webs in spots where you might reach without looking — making it easy to get bitten accidentally.

Why Brown Widow Spiders Are a Problem

While brown widow venom is generally considered less toxic than that of the black widow, their bite can still cause:

• Localized pain and swelling

• Muscle cramps and stiffness

• Headache or nausea in sensitive individuals

They also produce a large number of egg sacs, meaning a small spider problem can quickly multiply if left untreated.

How to Treat and Prevent Brown Widow Infestations

At TruPest Solutions, our 5-Point Pest Control Service is designed to protect Rialto and Fontana homes from dangerous and nuisance pests — including brown widows. Here’s how we handle them:

1. Thorough Inspection

We identify all active brown widow webs, egg sacs, and hiding areas inside and outside your home.

2. Web Removal

Physically removing webs and egg sacs is a key step in reducing spider populations and preventing re-infestation.

3. Targeted Exterior Treatments

We apply a professional-grade exterior power spray to spider harborage areas — around light fixtures, under eaves, patio furniture, and other hotspots.

4. Interior Crack & Crevice Treatment

For homes with indoor activity, we apply treatments to baseboards, window frames, and entry points to stop spiders from moving in.

5. Ongoing Prevention

With recurring pest control services, we maintain a protective barrier that keeps brown widows and other pests from returning.
