Get rid of ants with white vinegar spray: How to use it correctly & what experts recommend

Ants can quickly become a nuisance at home, particularly when they find an accessible source of food or water. While white vinegar is often recommended as a homemade remedy, it is important to understand what it can and cannot do.

A vinegar-and-water spray can help remove the scent trails ants use to navigate, which may make treated areas less attractive to them. However, vinegar is not a reliable way to eliminate an entire ant colony and should not be considered a substitute for ant bait or professional pest control when there is a persistent infestation.

How does white vinegar help get rid of ants?

Ants leave chemical scent trails that help other members of their colony locate food and follow established routes. Cleaning these trails can disrupt their movement.


White vinegar can be useful as a household cleaning solution because its strong smell and acidity can help clean surfaces and interfere with these trails. However, its effect is generally temporary once the vinegar smell fades.

How to make a white vinegar spray for ants

You can make a simple homemade spray by mixing:

• Equal parts white vinegar and water
• A clean spray bottle

Mix the solution and label the bottle clearly. There is no need to add other household chemicals.

How to use white vinegar spray correctly

1. Find where the ants are coming from

Look for cracks, gaps around doors and windows, areas around pipes and other possible entry points. Follow the trail to identify where the ants are travelling.

2. Clean the ant trail

Spray the vinegar-and-water solution onto the surface where ants have been travelling. Wipe the area thoroughly with a clean cloth.

3. Pay attention to entry points

After cleaning, you can use the solution around suitable non-porous surfaces near entry points. Once the area is dry, seal visible cracks and gaps where possible.

4. Remove food and water sources

Vinegar spray alone is unlikely to solve the problem if ants continue to find food or water. Clean crumbs and spills promptly, store food in sealed containers, empty rubbish regularly and fix leaking taps or pipes.

Does vinegar kill ants?

Vinegar should not be relied upon as an ant killer. It can kill some ants if they are directly exposed to concentrated vinegar, but a diluted household spray is primarily useful for cleaning and disrupting scent trails.

More importantly, spraying visible ants does not usually eliminate the colony or its queen.

What is recommended for a persistent ant infestation?

If ants keep returning despite cleaning and sealing potential entry points, commercial ant baits can be more effective because worker ants may carry the bait back to the colony. Always follow the product label and keep baits away from children and pets.

If there is a large or persistent infestation, or if you cannot identify its source, consider contacting a qualified pest-control professional.

Safety precautions when using vinegar spray

White vinegar is acidic, so avoid spraying it on surfaces that can be damaged by acids, including natural stone such as marble and some other stone surfaces. Test an inconspicuous area first if you are unsure.

Never mix vinegar with bleach or other cleaning chemicals, as dangerous fumes can be produced.

Note to readers: White vinegar spray can be a useful cleaning and ant-deterrent measure, particularly for wiping away ant trails. However, it does not reliably eliminate an established ant colony. A more effective approach is to combine regular cleaning with removing food and water sources, sealing entry points and, where necessary, using appropriately labelled ant baits or seeking professional pest control.
