You’ve scheduled professional pest control, had your home treated, and yet… ants are still crawling across your kitchen counter. Sound familiar? At Jacksons Mosquito & Pest Control, we often get calls from frustrated DFW homeowners who are still seeing ants after pest control—and in most cases, a few simple missteps are to blame. If you’ve recently had an ant treatment but aren’t seeing the results you expected, it’s worth checking for these common post-treatment mistakes.
While it’s tempting to expect instant results, ant control doesn’t always work like flipping a switch. Depending on the species, severity of infestation, and treatment method, it may take several days—or even a couple of weeks—for full colony elimination. That said, there are preventable errors that can slow or sabotage the effectiveness of even the best ant treatments.
Why You Might Still See Ants After Pest Control
It’s normal to see more ants immediately after a professional treatment. Many methods involve baiting, which attracts ants to carry product back to the colony. You might see increased activity as ants interact with the bait before dying off. That’s actually a sign that the treatment is working as intended.
However, if you’re still seeing high numbers of ants a week or two after service, it could mean:
- New ants are entering through unsealed cracks or gaps
- Food sources are still accessible inside the home
- Outdoor colonies were not addressed
- The type of ant requires a different treatment strategy
To get the full benefit of your investment, it’s important to support the treatment with proper aftercare.
Common Mistakes That Undermine Ant Treatments
1. Using Store-Bought Sprays After Professional Service
This is a big one. Many homeowners spot a few ants and reach for over-the-counter spray. But these repellents can interfere with the professional bait or treatment that was applied, driving ants into other areas and breaking the treatment cycle. Resist the urge to spray—it often does more harm than good. Learn more from this University of California IPM resource on ant baiting.
2. Leaving Food and Water Sources Accessible
Even the best pest control won’t work if ants have a buffet waiting for them. Dirty dishes, crumbs, leaky sinks, pet food, and even trash bins can attract ants and support a colony. After your service, keep all surfaces clean, store food in airtight containers, and empty trash regularly.
3. Not Sealing Entry Points
Ants can enter through the tiniest cracks around doors, windows, baseboards, and plumbing lines. Pest control reduces the population, but sealing up entry points ensures they don’t come back—or worse, start a new colony inside your walls. Check vulnerable areas and use caulk or weatherstripping where needed.
4. Ignoring Outdoor Nest Sites
Many infestations start outside, especially with species like fire ants or pavement ants. If your yard has ant mounds, tree nests, or mulch beds close to the house, those colonies must be addressed. Our DFW ant control service includes both indoor and outdoor treatments to cover all bases.
5. Not Following Up with Recommended Treatments
Depending on the severity and species, a single treatment may not be enough. For large colonies or aggressive species, we may recommend a follow-up visit in 2–4 weeks. Skipping it can give the ants time to rebound and start over. Trust your technician’s timeline—they know how ants behave in DFW conditions.
What You Can Do to Maximize Results
Getting rid of ants after pest control takes a team effort between you and your service provider. Here’s what you can do to support success:
- Keep counters, floors, and food storage areas spotless
- Fix leaky faucets and remove standing water
- Vacuum regularly and empty vacuum bags outdoors
- Trim vegetation touching the home
- Schedule follow-up treatments as needed
Consider combining your ant treatment with other services like flea and tick control or quarterly pest prevention to create a strong year-round barrier.
