Black widows are venomous spiders that are typically found in warm climates.

They are most easily identified by the red hourglass shape on their abdomen. Here are some signs that may indicate a black widow infestation:

1. Sightings of black widows: If you see one black widow spider in or around your home, there may be more. Black widows typically hide in dark, quiet areas such as closets, basements, and crawl spaces.
2. Spider webs: Black widows construct irregular webs that are typically found in corners, under eaves, and in cluttered areas.
3. Egg sacs: Black widow egg sacs are white or cream-colored and round, and they can contain hundreds of eggs. They may be found in or around spider webs.
4. Bite marks: Black widow bites can be very painful and can cause muscle cramps, spasms, and other symptoms. If you or someone in your home has been bitten and is experiencing symptoms, seek medical attention immediately.

If you suspect a black widow infestation in or around your home, it is important to contact a pest control professional for safe and effective removal.
