"Caleb, the Route Manager, came to our home and thoroughly explained their services and answered all questions regarding the products All Seasons Pest Control uses. The price was very reasonable, but more importantly, Caleb's professionalism and demeanor was so impressive, I signed up for their program. The very next morning, Spencer, the technician, showed up exactly on time as promised. He too, was very gracious and took the time to review the service and products he would be applying to my home. I watched as he meticulously covered every inch of property, at times double-checking his work. Spencer's professionalism, work ethic and attention to detail was off the charts! As "frontline" representatives of their company, I have no doubt I will be very pleased with All Seasons Pest Control for a long time to come. Kudos to Caleb and Spencer, and kudos to All Seasons for hiring such exemplary employees!"

"Mr. Morrow was professional, courteous, and attentive. He went above and beyond. I would definitely recommend him and would hire him again. There were a couple of false starts with what we were catching in the traps, and he took care of things with no fuss. I wish I would have found him when I first saw the groundhogs. All I can say is he is awesome and good at catching those pesky rodents."

Pest Control questions, answered by experts

In O'Fallon, if you notice live ants, termites, or spiders reappearing within a month after treatment, or find new termite mud tubes, chewed wiring, or fresh rodent droppings, it’s time to revisit pest control. Persistent mosquito activity, unexplained pet agitation, or water-damaged wood can also signal ineffective treatments. After heavy rainfall, check for washed-away barriers or reopened gaps around doors and windows.

Helpful?

For a seamless pest control project in O'Fallon, start by scheduling a termite inspection before peak swarm season. Identify and address drainage issues, and ensure all attic and crawl space access points are clear. Discuss any household allergies or sensitivities with your provider, and arrange for pets to be safely relocated during treatments. Plan for follow-up visits to monitor for recurring pest activity.

Helpful?

Your O'Fallon home is a strong candidate for pest control if you’ve noticed signs like termite mud tubes, carpenter ant sawdust, or mosquito breeding near standing water. Homes with unfinished basements, dense landscaping, or recent construction are at higher risk. If you live near wooded areas or water features, regular professional inspections can help prevent infestations and protect your property year-round.

Helpful?

In O’Fallon, keep a pump sprayer for perimeter insecticide applications, a bulb duster for attic or wall void treatments, and a moisture meter to monitor basements or crawl spaces. A sturdy inspection mirror helps spot pests in tight areas, while a caulk gun is essential for sealing gaps common in local brick or siding. Stock rodent bait stations and mosquito dunks for seasonal pest prevention.

Helpful?

After pest control in O’Fallon, check bait stations and replace any consumed baits within two weeks. Inspect basement and crawl space dehumidifiers monthly, especially after heavy rainfall. Reapply exterior treatments each spring and fall to counter seasonal pest surges. Schedule annual termite inspections and keep a log of pest sightings to help your exterminator adjust future home pest prevention strategies.
