What’s Covered

Pests Covered by Our ROS Program

One program, one price — all of the most common household pests in the St. Louis area are included in your bi-monthly service.

Ants (All Species)

Carpenter ants, odorous house ants, pavement ants — every ant species common to Missouri is covered under your ROS program.

Spiders (Including Brown Recluse)

General spider control including brown recluse management with targeted interior treatments in harborage areas, closets, and storage spaces.

Cockroaches

German roaches, American roaches, oriental roaches — interior and exterior treatments to eliminate existing populations and prevent reinfestation.

Wasps & Stinging Insects

Paper wasps, mud daubers, and other stinging insects. Nest removal and perimeter treatments to keep them from building near your home.

Silverfish & Earwigs

Moisture-loving pests that invade bathrooms, basements, and laundry rooms. Our treatments target the areas where they thrive.

Centipedes & Millipedes

These pests follow moisture and other insects indoors. Perimeter barriers and interior treatments reduce both them and their food sources.

Why Bi-Monthly?

One-time treatments wear off. Pests are persistent — they breed, they adapt, they find new entry points. Our bi-monthly rotation program provides continuous, overlapping protection that never gives pests a window to reestablish. It’s the difference between fighting fires and preventing them.

Our Process

How Our ROS Program Works — 4 Steps

From initial inspection to year-round protection, here’s exactly what to expect.

  1. Initial Service — Inside & Out — We start every new customer with a thorough initial service. Your technician inspects the interior and exterior of your home, identifying entry points, harborage areas, and conditions that attract pests. Inside, we treat all crack and crevice areas along baseboards and other key zones. Outside, we apply a full perimeter barrier treatment. We dust siding channels where pests hide and run a webster around the exterior to knock down cobwebs and egg sacs. The treatment is tailored to whatever pest pressure you’re dealing with and whatever’s most active that season.
  2. Bi-Monthly Return Visits — Every other month, your technician returns for a scheduled service. We refresh the exterior perimeter barrier, treat interior areas as needed, clear new cobwebs, re-dust siding channels, and adjust our approach based on seasonal pest activity. We rotate chemistries each visit so pests never build resistance to what we’re using.
  3. Seasonal Targeting — Missouri pest pressure changes with the seasons — ants and spiders in spring, mosquitoes and wasps in summer, rodents and overwintering pests in fall. Your bi-monthly service adapts to target whatever’s most active, so you’re always protected against the current threat, not last month’s.
  4. Callback Guarantee — See pests between visits? Call us and we come back at no additional charge. That’s not a marketing line — it’s how we operate. Your home is supposed to be pest-free, and if it’s not, we fix it.

Prevention

Homeowner Tips — Reduce Pest Activity

Keep Kitchen Clean

Wipe down counters, sweep floors, and clean up spills immediately. Food residue is the number one attractant for ants and roaches.

Seal Food in Containers

Store pantry items in airtight containers. Open bags and boxes are an invitation for pests to move in.

Fix Moisture Issues

Repair leaky faucets, running toilets, and poor drainage. Moisture attracts roaches, silverfish, centipedes, and earwigs.

Seal Exterior Cracks

Caulk gaps around doors, windows, pipes, and utility lines. Even small openings are highways for insects.

Trim Vegetation Touching House

Keep bushes, tree branches, and mulch at least 12 inches from your foundation. Overgrown landscaping creates pest bridges into your home.

Reduce Clutter in Storage Areas

Replace cardboard boxes with sealed plastic bins. Declutter basements, attics, and garages to eliminate hiding spots.
