Your Spring Pest Prevention Checklist for St. Louis Homes

Spring in St. Louis means warmer weather, blooming flowers — and bugs. After a quiet winter, pests become active again, and many of them are looking for ways into your home. The good news? A little prevention now can save you a lot of headaches later.

Here's my spring pest prevention checklist, based on what I see in St. Louis homes every year.

Inside Your Home

Kitchen and Pantry

The kitchen is ground zero for ant invasions. Here's what to check:

Clean behind appliances — crumbs and grease accumulate behind the stove and refrigerator
Check under the sink — fix any leaks and clean up moisture
Inspect pantry items — look for signs of pantry pests in flour, grains, and pet food
Store food properly — use airtight containers for anything open
Take out trash regularly — don't let it sit overnight

Bathrooms

Moisture attracts many pests, including silverfish, cockroaches, and some ants:

Fix dripping faucets and running toilets
Check for leaks under sinks and around tubs
Improve ventilation — run exhaust fans during and after showers
Don't leave wet towels on the floor

Basements and Crawl Spaces

These areas are prime entry points and hiding spots:

Inspect the foundation for cracks and gaps
Check for moisture — address any water intrusion
Look behind stored items — spiders and other pests love undisturbed areas
Consider a dehumidifier if humidity is consistently high

General Indoor Tasks

Vacuum regularly — gets rid of food particles and catches spiders and their eggs
Declutter — fewer hiding spots means fewer pests
Check window and door screens — repair any tears
Seal gaps around pipes and wires where they enter walls

Outside Your Home

Foundation and Exterior Walls

Most pest problems start outside and work their way in:

Inspect the foundation for cracks, gaps, and holes
Check where utilities enter — cable, electrical, plumbing penetrations are common entry points
Look at door sweeps — replace if worn or if light shows underneath
Examine window frames — look for gaps in caulking
Clear debris away from the foundation — mulch, leaves, and wood should be at least 12 inches back

Yard and Landscaping

Your yard can either attract pests or discourage them:

Trim bushes and trees away from the house — branches touching the roof are highways for ants and rodents
Clean out gutters — clogged gutters create moisture problems
Move firewood away from the house — store it at least 20 feet away and off the ground
Pick up fallen fruit from trees
Address standing water — birdbaths, plant saucers, and clogged drainage attract mosquitoes

Outdoor Structures

Don't forget about attached structures:

Check garage door seals — gaps let in all kinds of pests
Inspect shed foundations — these often harbor rodents and insects
Look under decks and porches — common nesting areas for wildlife

Seasonal Timing Tips

Spring pest prevention is most effective when timed right:

Early Spring (March-April):

Focus on sealing entry points before pests become fully active
Start ant prevention before you see the first scout
Clean out overwintering spots in the garage and attic

Mid-Spring (April-May):

Watch for carpenter bees around wooden structures
Monitor for ant activity, especially around the kitchen
Check for wasp nest construction under eaves

Late Spring (May-June):

Mosquito prevention becomes important as temperatures rise
Watch for increased spider activity
Consider a foundation perimeter treatment for ongoing protection

When Prevention Isn't Enough

Sometimes, despite your best efforts, pests still find their way in. That's normal — no home is perfectly sealed. Here's when to call me:

You're seeing ants repeatedly despite cleaning and sealing efforts
You've found a few brown recluse spiders — could indicate an established population
You're noticing new pest activity in previously clear areas
You want professional-grade prevention — I can apply barrier treatments that last longer than DIY products

The Bottom Line

Spring pest prevention isn't complicated, but it does require attention to detail. The homes that stay pest-free are the ones where someone takes 30 minutes every spring to do a thorough inspection and address the issues they find.

If you'd rather have a professional handle it, I'm happy to do a walkthrough and point out potential problem areas — no obligation. Sometimes a trained eye catches things you might miss.
