How to Get Rid of Piss Ants (The Complete 2025 Guide)

By | October 10, 2025

Piss ants are often spotted in kitchen cabinets and near the sugar jar or the sink. They are tiny, quick, and surprisingly stubborn. Even after you clean everything spotless, they somehow find their way back. But do not worry.

This guide will show you exactly how to get rid of piss ants for good, using proven methods trusted by pest control experts.

What Are Piss Ants?

The name “piss ant” is not scientific it is just a nickname people use for tiny ants that invade homes, especially kitchens and bathrooms. Most of the time, they are ghost ants or sugar ants, species that love moisture and sweets. They are incredibly small (around 1 to 2 millimeters long) with light colored bodies, making them hard to spot.

You will often find them near sinks, drains, or even houseplants. What makes them tough to kill is their complex colony system, one nest can split into many smaller ones, and they move fast when threatened. That is why killing the few ants you see does not stop the problem. You need to reach the whole colony, including the hidden queens.

Why Do Piss Ants Invade Our Homes?

Like most pests, piss ants are not invading out of spite they are looking for food, water, and shelter. Crumbs on the counter, pet food, sticky soda spills, or even a dripping faucet can attract them.

They prefer warm, damp areas, so kitchens, bathrooms, and laundry rooms are their favorite hangouts. Once they find a reliable food source, they leave a scent trail (pheromone path) to guide other ants to the jackpot. Before long, you will see dozens following the same route like a tiny ant highway.

How to Tell If You Have a Piss Ant Infestation

You will usually know you have a problem if you see:

  • Ant trails along countertops, walls, or baseboards
  • Clusters of ants near sugary foods or water sources
  • Tiny nests in wall cracks, behind appliances, or in potted plant soil

Even if you only see a few, do not ignore them. Piss ants reproduce fast, and one small colony can turn into thousands within weeks.

Why Spraying Piss Ants Often Makes It Worse

Many people grab a can of ant spray the second they see movement, but that can backfire. Regular sprays kill only the ants you see and often cause the colony to scatter. When this happens, each group forms a new nest, spreading your infestation instead of solving it.

Experts recommend avoiding repellent sprays and focusing on non-repellent insecticides or bait traps. These methods let ants take the poison back to the colony, silently killing it from the inside.

Step-by-Step Guide to Get Rid of Piss Ants

1. Clean Everything Thoroughly

Start by removing what attracts them. Wipe up spills, seal food in airtight containers, clean under appliances, and take out the trash daily. Ants will not stick around if there is no food for them.

Also, dry out sinks and counters at night, piss ants love moisture. Fix any leaky pipes or faucets that might keep the area damp.

2. Seal Entry Points

Check windows, door frames, and baseboards for cracks or gaps. Ants can crawl through the tiniest spaces, so seal them with caulk or weather stripping. Outside, trim trees or shrubs that touch your house since they can act like bridges for ants to climb inside.

3. Use Ant Bait Instead of Spray

The best method for killing piss ants is this one. Baits function by combining a slow-acting poison with food, such as sugar. The ants carry the poison back to their hidden colony, where it spreads to other ants and the queen.

You can buy ready-made gel or liquid baits, or make a simple homemade version:

  • Mix 1 tablespoon of borax with 3 tablespoons of sugar and a bit of warm water.
  • Place the mixture on cotton balls or small lids near ant trails (but out of reach of kids and pets).

Be patient, it might take a week or two for the full colony to die, but it works far better than spraying.

4. Try Natural Solutions

If you prefer a more eco-friendly approach, here are a few natural methods that help control ants:

  • Vinegar spray: Mix equal parts vinegar and water to wipe down ant trails—it removes their scent paths.
  • Diatomaceous earth: Sprinkle this powder along baseboards; it dries out ants on contact.
  • Essential oils: Peppermint, tea tree, or lemon oil can repel ants naturally. Mix a few drops with water and spray in problem areas.

These won’t destroy a large infestation, but work well for prevention and maintenance.

5. Treat the Outside Too

Ants often live outdoors and wander inside for food. Apply a non-repellent perimeter spray around your home’s foundation, patio, and doorways. You can also pour boiling water directly into visible outdoor nests to reduce the population. Just be cautious with plants and surfaces nearby.

How to Keep Piss Ants Away for Good

Once the ants are gone, prevention is key.

  • Empty garbage regularly and clean bins.
  • Fix leaks and reduce indoor humidity.
  • Store pet food in containers with lids.

Reapply perimeter treatments every few months if you live in an ant-prone area.

What prevents them from coming back is consistency. They can return with just one forgotten spill.

When to Call an Expert

If you have tried everything and ants keep coming back, it is time to call an experienced pest control technician. Professionals use commercial-grade baits and non-repellent treatments that reach deep into walls, under floors, and hidden crevices where colonies thrive.

A trustworthy company will inspect your home, explain their process, and usually offer a guarantee to retreat if the ants return. This approach is especially worth it if you are dealing with a severe or recurring infestation.

Common Mistakes to Avoid

Even well-meaning homeowners make these missteps:

  • Using repellent sprays that scatter colonies.
  • Cleaning away bait too soon. You need to let ants feed and carry it home.
  • Stopping treatment too early. Keep baits out for several weeks.
  • Ignoring outdoor nests. The source might be outside, not just under your sink.

Avoid these, and you will have a much better chance of staying ant-free.

Final Thoughts

After years of dealing with piss ants in homes and businesses, one thing has become clear there is no quick spray-and-done solution. These tiny pests are smart, stubborn, and deeply rooted in hidden colonies that most people never see. But with the right approach, you can beat them.

The secret is not brute force, it is strategy. Keep your home clean so they have no reason to stay, seal every tiny entry point they use, and rely on slow acting baits that reach deep into their nests. Patience pays off. Each foraging ant that carries bait home brings you one step closer to wiping out the entire colony.

Frequently Asked Questions

1:How long does it take to get rid of piss ants?

Usually 1 to 3 weeks. The bait needs time to reach the queen and all the worker ants.

2: Can vinegar alone kill ants?

Not really. Vinegar breaks their scent trails, which helps, but it doesn’t kill the colony.

3: Is borax safe to use around pets?

Borax can be harmful if eaten, so keep homemade baits out of reach from kids and animals.

4: Why do ants come back after spraying?

Sprays often push them into hiding or cause them to form new nests. Use bait instead.

5: Do I need a professional exterminator?

If the infestation keeps returning or you can not find the nests, yes. Experts can locate hidden colonies and treat them safely.
