Pest Library FAQs

Straightforward answers about identifying, preventing, and managing common household pests.

  • How do I identify what type of pest is in my home? Toggle answer for: How do I identify what type of pest is in my home?

    Start by noting where you see the pest, what time of day it appears, and any physical features you can observe, size, color, wings, number of legs. Look for droppings, damage patterns, or entry points nearby. Our Pest Identification Guide groups common pests by category with images and descriptions to help you match what you are seeing.

  • What are the most common household pests in the U.S.? Toggle answer for: What are the most common household pests in the U.S.?

    The most common household pests include ants, cockroaches, spiders, mice, rats, bed bugs, termites, fleas, and wasps. The specific pests you encounter depend on your region, climate, and the conditions around your home, moisture levels, food access, and structural gaps all play a role.

  • Why do pests keep coming back after treatment? Toggle answer for: Why do pests keep coming back after treatment?

    Recurring infestations usually mean the root cause has not been addressed. Over-the-counter products often eliminate visible pests but do not reach nests, colonies, or entry points. Ongoing moisture issues, unsealed gaps, and accessible food sources can continue attracting pests even after surface-level treatment.

  • What is the difference between a pest sighting and an infestation? Toggle answer for: What is the difference between a pest sighting and an infestation?

    A single sighting may be an isolated event, astray insect that wandered in through an open door. An infestation means pests have established a presence in your home. Signs include repeated sightings over several days, droppings or damage in more than one area, nesting material, or activity at consistent times of day.

  • When should I call a professional instead of handling it myself? Toggle answer for: When should I call a professional instead of handling it myself?

    If you're seeing pests daily, in multiple rooms, or noticing structural damage, droppings, or bites, call a professional. Over-the-counter products treat what you can see but rarely reach nests, colonies, or hidden entry points. A professional identifies the species, maps the full scope, and applies targeted treatment that addresses the source, not just the symptoms.

  • Are certain pests more active during specific seasons? Toggle answer for: Are certain pests more active during specific seasons?

    Yes. Ants, mosquitoes, and wasps are most active in warmer months, while rodents, stink bugs, and other occasional invaders tend to move indoors when temperatures drop in fall and winter. However, some pests like cockroaches, bed bugs, and termites remain active year-round regardless of season.

  • How can I prevent pests from entering my home? Toggle answer for: How can I prevent pests from entering my home?

    Seal cracks and gaps around doors, windows, pipes, and the foundation. Fix moisture issues like leaky faucets and poor drainage. Store food in airtight containers, keep trash sealed, and reduce clutter in storage areas. Trim vegetation away from exterior walls and remove standing water from your yard. Regular inspections of attics, basements, and crawl spaces help catch early signs before they become larger problems.
