Spiders Identification Guide

Physical Characteristics

Spiders come in many sizes, colors, and appearances. They have eight legs, two body parts (the head-chest area and the abdomen), and fangs that inject venom. Most spiders have multiple eyes in distinct patterns. Wolf spiders have thick, hairy legs for hunting. Orb-weavers have thin legs for building webs.

Common Species

  • House Spider (Parasteatoda tepidariorum)

  • Wolf Spider (Lycosidae family)

  • Cellar Spider (Pholcidae family)

  • Orb-Weaver Spider (Araneidae family)

  • Black Widow (Latrodectus mactans)

  • Brown Recluse (Loxosceles reclusa) - Rare but possible

Spiders Behavior and Biology

Spiders are predators that eat insects and other small bugs. Most use venom to catch their prey, but only a few can harm humans. Web-building spiders create traps to catch food. Hunting spiders chase and pounce on their prey. Female spiders lay eggs in silk sacs. Some species guard their young until they can survive on their own.

How We Treat for Spiders

Spiders need a different approach than other crawling insects. They enter homes in many ways. Our process includes:

  • Inspection. We check for spider activity inside and outside your home.

  • Treatment. We apply a non-repellent product to exterior areas where spiders gather. This includes windows, doorways, and corners. We also treat high-activity areas inside.

  • De-webbing. We remove reachable webs (up to 6-8 feet high) to reduce spider numbers.

  • Ongoing Control. Our seasonal plan includes regular visits. We also share tips on reducing attractants like bright lights and moisture.

Common Questions about Spiders

How do spiders get inside my home?

+

Spiders enter homes through cracks, gaps in doors and windows, vents, and utility openings. Some are carried in on firewood, boxes, or plants.

Are spiders dangerous?

+

Most spiders are harmless, but some, like black widows and brown recluses, can deliver venomous bites. These bites are rare and usually occur when the spider is disturbed.

Will spraying for spiders eliminate them completely?

+

Spider treatments reduce their presence but do not create an instant eradication. Since they do not groom themselves like insects, direct contact with treated surfaces is necessary for control. Regular service is key to long-term results.

Do you remove spider webs?

+

Yes, we remove reachable spider webs (up to 6-8 feet high) during service visits. However, customers are encouraged to vacuum webs inside their homes for additional control.

What can I do to reduce spider problems?

+

Reducing exterior lighting, sealing entry points, managing moisture, and removing clutter can help deter spiders. Regular pest control treatments further reduce food sources and spider activity.

How often should I have my home treated for spiders?

+

We recommend tri-annual treatments (three times per year) to maintain a protective barrier and prevent re-infestations. This schedule also helps with other common household pests.

Will this treatment affect other pests?

+

Yes, our spider treatment plan also helps control other insects that serve as a food source for spiders, making it a comprehensive pest management solution.

Do you use strong chemicals to treat for spiders?

+

We have removed 9 of the harshest chemicals commonly used in the industry and instead use reduced-risk products like Essentria, Alpine, and Borate-based solutions. Our treatments are designed to be effective while considering environmental impact.

Can I cancel my spider treatment plan at any time?

+

Yes, we do not lock customers into contracts. You can cancel with 30 days' notice if you're not happy with the results.
