  • These pests live in tropical climates, but they sometimes travel farther north.

  • While more toxic than a black widow, a brown widow injects less venom, so its bite is usually less severe.

What Do Brown Widow Spiders Eat?

These spiders feed primarily on insects they catch in their webs such as mosquitoes, flies, and beetles.


Females lay egg sacs that contain up to 250 eggs. Once hatched, young brown widow spiders feed in a small area near their sac for a few weeks before departing. Adult females live up to two years, while the male brown widow lifespan is only a few months long.


  • Look for spider webs in dark corners or rafters.
  • Search under windowsills or ledges for white, spikey egg sacs.
  • Check for dead brown widow spiders near windows or crawlspaces.

Problems Caused by Brown Widow Spiders

A female brown widow spider may bite if handled, but it would rather try to escape. When the pests do strike, the results can be unpredictable. Some bites inject no venom and are not painful. Others produce symptoms from nausea to more severe reactions. Consult a doctor for the right treatment.

Signs of Infestation

These arachnids mostly live in the southern U.S., though they may travel to other areas on imported plants and packages. Once inside the house, brown widow spiders tend to nest in quiet, secluded areas. Check basements or attics for an excessive amount of spider webs.

Prevention Tips

Brown widow spiders can survive inside or outdoors. In yards, remove wood piles and debris to deprive the pests of hiding places. Residents can also clean the gutters and eaves of homes to get rid of spider webs.

Tips for Removal from Home

To slow down an infestation, vacuum away webs and egg sacs. Immediately take out vacuum bags, place them in a sealable bag, and take them to an outdoor garbage container. For further assistance, contact a local pest control company.
