Black Widow Spider

Black widow spiders are common across the valley. The female is shiny black with a distinctive red hourglass under her abdomen.

Recognizing the female black widow

Female black widows are shiny black with a distinct red hourglass marking on the underside of the abdomen. They inhabit sheltered outdoor areas across southern Nevada residential yards.

Where black widows build webs

  • Block walls and garages

    Spiders build webs along block walls, garage corners and dark storage spaces.

  • Meter boxes and utilities

    Irrigation, utility and water meter boxes offer sheltered locations for web construction.

  • Patio furniture and storage

    Undersides of patio chairs and stored yard items frequently host widow spiders.

Black widow spider bites

A bite from a black widow spider requires medical advice. Seek professional medical evaluation if a bite is suspected.

How Whiptail treats spider activity

We inspect exterior perimeter zones, block walls and harborage sites before applying treatments. Exterior perimeter applications and targeted crack-and-crevice work keep spider populations managed. Quarterly home pest plans cover black widow spiders with included re-services between visits.

Dana did a blacklight inspection at night and found bark scorpions in our block wall. She treated the yard and installed weep screen guards. Now our Scorpion Plan includes visits every two months.

We needed a formal Wood Destroying Insect report to sell our house. Marco came out and inspected the slab and garage thoroughly. He sent the written report to our agent the next business day.

We heard scratching in the attic. Luis found where roof rats were getting in, sealed the entry points with steel mesh, and set traps. He came back to check the traps just like he promised.

We use the quarterly plan for ants and spiders. When we saw a few ants return near the kitchen in summer, they came back out and treated the area again at no charge.
