What Are Spiders?

What Are Spiders?

Spiders are arachnids that feed on insects, helping control other pests naturally. However, some species, like the brown recluse and black widow, can be dangerous and unwelcome in homes.

What Kinds of Spiders Are There?

  • House Spider – Common indoors; builds cobwebs in corners.

  • Wolf Spider – Large, fast, and often mistaken for tarantulas.

  • Brown Recluse – Venomous, identified by a violin-shaped mark.

  • Black Widow – Glossy black with a red hourglass marking.

How to Identify Spiders

  • Eight legs and no antennae.

  • Range in size from a few millimeters to over an inch.

  • Webs found in corners, attics, and basements.

Habitat & Behavior

Spiders prefer dark, undisturbed areas and build webs to capture prey. They become more noticeable when other insects are abundant.

Why Spiders Are a Problem

Most spiders are harmless, but venomous species pose medical risks. Even non-dangerous ones cause fear and nuisance in homes.

Signs of a Spider Infestation

  • Webs or egg sacs around ceilings and vents.

  • Visible spiders in corners or basements.

  • Increase in insect activity (their food source).

How Sleep Tight Solves Spider Problems

  1. Inspection: Locate nests and feeding sites.

  2. Web & Egg Removal: Clear visible webs and sacs.

  3. Residual Barrier Spray: Prevent future activity.

  4. Reduce Food Source: Treat other insects that attract spiders.

Prevention Tips
