Step 1: Protect Your Home Before Day One
The weeks between closing and moving in are your best window to address pest issues — before your furniture, belongings, and family are in place.
A Wood-Destroying Insect (WDI) inspection is different from a standard home inspection. It specifically checks for termites, carpenter ants, carpenter bees, and powder post beetles. Many lenders require one, but even if yours does not, it is one of the smartest investments you can make in the St. Louis market.
Ask the seller or their agent for any records of previous termite treatments, bait systems, or damage repairs. Missouri disclosure laws require sellers to report known termite issues, but having the full treatment history helps your pest control provider build a better protection plan.
Have a pest professional walk the exterior of your new home and identify gaps, cracks, and entry points that rodents, insects, and wildlife could use to get inside. Sealing these before you move in is far easier than dealing with an infestation later.
These are the two areas most likely to harbor hidden pest activity — from rodent nesting to termite damage to wildlife intrusions. A professional inspection before move-in catches problems while they are still easy to address.
Step 2: Establish Protection in Your First Month
Your first month in a new home sets the tone for long-term pest management. These are the services that should be in place before the first season change.
- Initial Pest Service — A comprehensive interior and exterior treatment that creates a barrier around your home. This addresses any existing pest activity and establishes a protective perimeter. In the St. Louis area, this is especially important for ants, spiders, and roaches that thrive in our humid climate.
- Sentricon Termite Baiting System — Missouri is one of the highest-risk states for subterranean termites. If your new home does not already have an active termite protection system, installing Sentricon stations around the foundation is the most effective way to detect and eliminate termite colonies before they reach your home.
- Rodent Exclusion — Seal gaps around utility penetrations, dryer vents, garage door seals, and foundation cracks. Mice can squeeze through an opening the size of a dime. Proper exclusion now prevents a winter rodent problem later.
- Address Any Findings from Your WDI Inspection — If your pre-purchase inspection identified activity or damage, now is the time to treat and repair. Do not wait for the problem to spread. The longer termite or carpenter ant damage goes unaddressed, the more expensive the repair.
Step 3: Keep Your Home Protected Year-Round
Pest control is not a one-time event. The St. Louis climate brings different pest pressures every season — and consistent, professional service is what keeps them outside where they belong.
Our quarterly service program provides year-round exterior and interior treatments tailored to the current season’s pest activity. Spring ants, summer wasps, fall spiders, winter rodents — each visit addresses what is actually active in the St. Louis area at that time.
Your technician adjusts the treatment strategy each quarter based on current conditions. A wet spring means heavier mosquito and ant pressure. A cold snap pushes rodents indoors. Seasonal awareness is what separates professional pest management from one-size-fits-all spraying.
If you have Sentricon installed, your stations are monitored on a regular schedule to detect termite activity early. Annual inspections of the structure itself catch any signs of new activity or moisture conditions that attract termites.
Keep records of every pest service, inspection report, and treatment performed on your home. This documentation is valuable for your own records, for insurance purposes, and for future resale — buyers want to see a well-maintained pest history.
Why New Construction Homes Need Pest Control Too
Many new homeowners assume that a brand-new house is pest-free. That is a costly misconception. Here is why newly built homes in the St. Louis area are actually at elevated risk for pest problems:
- Construction disturbs soil and exposes termite colonies
- Fresh lumber and wood framing attract wood-destroying insects
- Gaps in new construction invite rodents and insects
- Landscaping mulch placed against foundations creates pest highways
- Pre-treatment chemicals applied during construction wear off within a few years
- New developments built on former farmland have higher termite density
- Grading and drainage issues create moisture that attracts pests
- Neighboring construction keeps pest populations actively moving
Whether your home is brand new or 50 years old, proactive pest management is the only way to protect your investment in the St. Louis market.
WDI Inspections & Termite Clearance Letters
Whether you are buying, selling, or refinancing — we provide the documentation your lender and real estate agent need.
WDI Inspection for Home Purchase
A Wood-Destroying Insect inspection (NPMA-33 form) is the industry-standard report that documents whether termites, carpenter ants, carpenter bees, or powder post beetles are present. Many lenders — especially VA and FHA — require this before closing. We provide fast turnaround so your transaction stays on schedule.
Termite Clearance Letter
If you are selling your home, a termite clearance letter from a licensed pest control company confirms that no active wood-destroying insect activity was found. This gives buyers confidence and prevents last-minute delays at closing. We can typically schedule and complete this within a few business days.
