3 Costly Mistakes Make Getting Rid of Ants Fail Again

3 mistakes explain why getting rid of ants often fails: homeowners kill the insects on the counter, erase the evidence too early, and never reach the colony that keeps sending replacements.

That’s the practical warning from pest control expert Ed Dolshu, vice president of business development and technical director at Catchmaster, who told Tom's Guide that a lone ant is usually not random. It’s scouting for food or water and laying a scent route others can follow.

“That single ant is mapping a route to a food or water source and laying down a scent trail for the rest of the colony to follow,” Dolshu said.

By the end of this guide, you’ll know how to stop the repeat cycle: map the trail, remove the attractant, use bait that reaches the nest, then reduce re-entry points.

XOOMAR analysis: this is a source problem, not a surface problem. The same habit we apply when reading repeated signals in AUD/USD resistance coverage or product strategy shifts like Meta Pocket’s AI game experiment applies here. Don’t react to the visible signal first. Find what’s producing it.

3 mistakes keep the ant colony alive after the counter looks clean

The headline mistake in getting rid of ants is treating visible workers as the whole problem. Dolshu’s point is blunt: workers are replaceable. If the queen and colony remain active, the nest can keep producing ants.

Here’s the better framing:

Dolshu told Tom’s Guide that pouring hot water on a mound or knocking it down can look productive, but workers can clear tunnels and rebuild while the colony keeps working underground.

“You haven’t solved the problem; you’ve just interrupted it,” Dolshu said.

Before you start: watch the ant trail for 1 minute

Don’t grab spray as your first move. Watch.

Dolshu’s advice is simple: observe the ants before wiping the trail away. Their movement can show where they’re entering, where they’re feeding, and what attracted them in the first place.

“Watch it for a minute before you do anything. They’ll lead you toward the entry point or the food source. That's the information you want.”

Use only what you need:

• Paper towel or cloth: For wiping trails after you’ve learned the route.
• Diluted white vinegar or soapy water: Dolshu says both can break up scent trails.
• Ant bait: Dolshu recommends liquid ant bait because workers carry it back into the colony.
• Food storage containers: Useful if crumbs, open pantry items, or pet food are drawing scouts.
• Appropriate sealant: Helpful later if you identify obvious gaps around doors, windows, pipes, or other entry points.

Watch out for: If you suspect carpenter ants, don’t treat the issue as a routine kitchen nuisance. Dolshu warns they tunnel into wood and damage can build quietly. Fire ants are also different because they sting, and for people with allergies, that can become a medical issue.

Step 1: Stop treating worker ants as the target

The fastest way to feel like you did something is to squash the ants or spray the trail. That doesn’t mean you solved anything.

Dolshu told Tom’s Guide that killing the ant you see may only buy time if you don’t remove what attracted it.

“If you kill it and move on, you've bought yourself a day. If you don't address what attracted it, you'll have a trail of workers through that same path very soon.”

The same warning appears in related pest control guidance from Specter Pest Control, which says homeowners often fail by treating only the ants they see instead of the colony behind them.

Do this instead:

1. Pause before killing the trail: Learn where ants are going.
2. Find the attractant: Look for crumbs, sticky spills, pet food, moisture, or grease.
3. Shift from contact killing to colony control: The goal is not a clean counter for one afternoon. The goal is stopping the source.

If ants are in a food prep area, clean the surface for hygiene. Then return to the bigger job: finding why they entered and how to reach the colony.

Step 2: Use ant bait to reach the queen, not just the trail

Ant bait works because it uses ant behavior against the colony. Dolshu recommends liquid ant bait that workers carry back into the nest.

“You’re using their own behavior against them. Once the queen goes, the colony goes.”

That’s the core of effective getting rid of ants. You’re not trying to win a one by one fight against workers. You’re trying to get material into the colony.

Follow the bait product’s label. Keep it away from children and pets. Don’t mix random treatments around it unless the product instructions say to. The supplied sources don’t give a universal placement formula, so don’t improvise aggressively. Put the bait where the label permits and where ant activity confirms there is a route.

Watch out for: Spraying around a baiting effort can work against the goal if it stops workers from taking bait back. Specter Pest Control also warns that not all products work the same way and that using too many products at once can reduce effectiveness.

Step 3: Remove the crumb, spill, leak, or pet food that invited scouts

The second major mistake is killing ants while leaving the reason they arrived.

Dolshu listed ordinary attractants: a crumb behind the toaster, a sticky spill under the fridge, or a leaky pipe under the sink. His advice is to find that source and cut off the reason ants are scouting there.

Use this cleanup pass:

• Counters: Wipe sticky spots and food residue.
• Appliance edges: Check behind or under the toaster, fridge, and other crumb traps.
• Recycling: Rinse containers before they sit indoors.
• Pet food: Don’t leave it sitting out if ants are feeding there.
• Grease: Clean grill grease and kitchen grease that may draw ants.
• Moisture: Check under sinks for leaks or damp areas.

Dolshu put it plainly:

“Ants are in your kitchen because there's a reason to be there. Take away the food, water or shelter source, and scouts will stop reporting back.”

Step 4: Wipe scent trails with vinegar or soapy water after you’ve learned the route

Ant trails are information. Don’t destroy that information before reading it.

Once you know where ants are coming from and where they’re going, Dolshu says you can wipe the trail with diluted white vinegar or soapy water. That breaks up the scent trail ants follow.

Focus on the actual route you observed:

• Door thresholds
• Entry points
• Cabinet edges
• Counter routes
• Base areas near appliances
• Paths toward food or water

This won’t necessarily end an active colony by itself. Dolshu warns that if ants keep coming back, the colony is still active.

“Surface treatment just resets the clock. You have to get to the source.”

So use wiping as a disruption tool, not as the whole plan for getting rid of ants.

Step 5: Seal entry points, but don’t pretend one blocked gap kills the nest

Sealing gaps helps prevention. It does not collapse a colony on its own.

Specter Pest Control lists gaps around windows and doorways among common reasons ants keep gaining access. Dolshu also points readers back to the source problem: food, water, shelter, and the active colony.

After you’ve identified likely routes, reduce access where practical:

• Windows and doors: Look for obvious gaps around frames and thresholds.
• Pipes and utility openings: Check where lines enter cabinets or walls.
• Baseboards: Inspect routes ants used indoors.
• Outdoor storage: Keep firewood and similar materials from becoming easy staging areas near the house.
• Vegetation and exterior contact points: Specter flags branches, mulch, and materials too close to the home as potential contributors.

Moisture matters too. Dolshu specifically names a leaky pipe under the sink as the kind of source that can keep scouts interested.

Step 6: Use natural deterrents carefully, and skip the fake fixes

Natural methods can help when ant activity is light, but Dolshu is clear about their limits.

Useful options from the source:

• Diluted white vinegar: Disrupts scent trails.
• Soapy water: Also breaks up trails.
• Diatomaceous earth outdoors: Dolshu says it can be used as a barrier, but it must be reapplied after rain.

Methods Dolshu says to avoid:

• Boiling water on mounds
• Essential oils
• Strongly scented sprays

“The boiling water rarely reaches the queen, it just damages whatever surface you’re pouring it on. The scent-based stuff might move a few ants temporarily, but it's not a control strategy,” Dolshu said.

That distinction matters. Deterring a few workers is not the same as eliminating the colony.

Call a pest control pro for carpenter ants, fire ants, or repeat indoor trails

DIY treatment has limits. Dolshu recommends asking what kind of ants you’re dealing with, how widespread the problem is, and whether there is structural or health risk.

Call a professional if:

• You can’t find the source
• Ants appear in multiple rooms
• There are multiple mounds outside
• Ants keep returning after bait
• You suspect carpenter ants
• Fire ants create a sting risk
• There is a vulnerable person in the home who may face added risk

Dolshu’s warning is direct:

“If you can't find the source, you can't solve the problem, you're just managing symptoms.”

For common household ants, contamination is the main food concern. Dolshu says ants travel across drains, garbage, outdoor surfaces, and animal waste, picking up bacteria that can spread into food.

Quick recap: stop these 3 ant-removal mistakes today

If ants keep returning, stop repeating the same surface-level moves.

• Don’t rely on spraying or squashing: Workers are replaceable.
• Don’t wipe too soon: Watch the trail first so it shows the entry point or food source.
• Don’t ignore the colony: Use bait that workers can carry back to the nest.
• Don’t leave attractants behind: Remove food, water, grease, pet food, and shelter sources.
• Don’t delay on risky ants: Carpenter ants and fire ants change the risk profile.

The practical formula is simple: watch the trail, bait the colony, clean the reason, disrupt the scent route, then reduce re-entry points. If the same trail returns after that, the next action is not more guessing. It’s time to bring in a pest control pro.

Key Takeaways

• Killing ants on the counter can leave the colony intact and allow the problem to return.
• Tracking ant trails helps homeowners find the food, water, or entry point causing the infestation.
• Using bait and sealing re-entry points addresses the source instead of just the visible symptoms.
