Spiders in your home are more than a nuisance—they’re a sign that insects (their primary food source) are present in or around your property. At Colonial Pest Control, we’ve protected family homes across Massachusetts and New Hampshire since 1984 with a reliable, professional approach that homeowners trust. Most spiders in New England are harmless and even beneficial because they eat other pests, but large numbers or visible webs signal it’s time for expert help.
Our spider control service combines Integrated Pest Management (IPM), strong cultural controls, mechanical removal, and targeted treatments only when needed. We start with a thorough clean-out to eliminate the immediate problem, then guide you into our Preventative Maintenance Program—the best long-term solution for keeping spiders and their insect prey out of your home for good.
Why Spiders Invade MA & NH Homes
Common New England spiders include the American house spider, cellar spider (daddy longlegs), wolf spider, jumping spider, and triangulate cobweb spider. These arachnids thrive indoors year-round in our climate because homes provide warmth, shelter, and food.
They enter through small gaps, cracks, and around doors/windows, or hitchhike on firewood, boxes, or plants. Spiders congregate where insects gather—near outdoor lights, in basements, attics, garages, crawl spaces, and cluttered storage areas. Signs include:
- Webs in corners, ceilings, eaves, or behind furniture
- Papery egg sacs (often hidden)
- Tiny white/gray/brown fecal spots on surfaces
- Increased sightings, especially in fall/winter as outdoor insects seek shelter
Rarely, you may encounter a Northern black widow (very uncommon in MA/NH and shy). Brown recluse spiders are not established here, rarely may be found in hidden spots. Most “spider bites” are actually from other causes. We identify the species and address the real issue during every inspection.
Our IPM Approach: Prevention First, Targeted Solutions Always
Colonial Pest Control follows a true Integrated Pest Management (IPM) strategy—the gold standard recommended by NPMA and responsible New England pest professionals. We prioritize non-chemical methods and only use EPA-registered, low-impact products when necessary. This protects your family, pets, and the environment while delivering superior results.
Cultural Controls & Habitat Modification (Prevention at the Source)
We inspect for and advise on conditions that attract spiders and their prey:
- Reduce outdoor lighting or switch to shielded/yellow bulbs that draw fewer insects
- Move firewood, lumber, and debris away from the foundation
- Trim vegetation and eliminate clutter in garages, attics, and basements
- Fix moisture issues (leaks, poor ventilation) and recommend dehumidifiers in damp areas like cellars
- Declutter and store items in sealed plastic bins
These simple changes dramatically reduce spider populations long-term.
Mechanical & Physical Controls (Immediate Clean-Out)
Our technicians will advise on any procedures that you can take to enhance our treatment. This may include vacuuming harborage areas, sweeping out webs, or installing removal devices to gain quick control. Our technicians may even perform a cobweb sweep of the house to get you started.
Exclusion (Keeping Them Out)
We identify entry points and recommend or perform sealing of gaps, cracks, and penetrations. Adding door sweeps, weatherstripping, and tight-fitting screens stops both spiders and the insects they eat from entering.
Targeted Treatments (Smart, Minimal Pesticide Use)
When insect food sources (silverfish, ants, drain flies, carpet beetles, etc.) are present, we use precise, low-volume applications—primarily exterior perimeter treatments. Spiders rarely contact broadcast sprays because they stay in webs or retreat into crevices, so we focus on results, not unnecessary chemicals.
Ongoing Preventative Maintenance: The Smartest Path
Our initial clean-out service for spider control sets you and your home on the right path for long-term control and prevention. Spiders are tenacious invaders, and their prey food are likely to enter your home continuously unless ongoing preventive measures are taken. That’s why our comprehensive Preventive Maintenance Program covers you for spiders and their common snacks of choice. We also offer legendary AprilAire dehumidification services to complete the holistic approach to the best pest control.
