How to get rid of an ant infestation

Ants are a common nuisance in London homes and businesses, particularly during warmer months. While they’re not dangerous, their presence in kitchens or food areas is unhygienic and frustrating. Colonies can grow quickly, and DIY solutions often don’t address the root cause.

How to get rid of ants

Ants

Why do I have ants in my house?

Ants come indoors looking for food, water and shelter, especially in warmer months or during wet weather. They often build colonies just outside your home and use tiny gaps around doors, windows and pipework to get in. Without proper control and proofing, the same trails will be used again and again, which is why a professional ant treatment and some simple prevention steps from Pestpatrol can make such a difference.
Ants

Does ant spray work?

Shop bought ant sprays can kill the ants you see on worktops or floors, but they rarely reach the nest, so more workers soon appear. In many cases, spraying the trails alone can actually scatter the colony and make it harder to treat. Pestpatrol uses professional gels and baits that are carried back to the nest, providing a far more effective and longer lasting solution than surface sprays on their own.

How to find an ant nest

You can sometimes locate a nest by following ant trails back to cracks in walls, gaps under skirting boards or holes in paving, flowerbeds and lawns outside. However, many nests are hidden in voids, under floors or outdoors where they are hard to reach. A Pestpatrol technician can track activity, identify likely nest sites and apply targeted treatments to deal with the colony properly.

Pestpatrol ant control

Investigate

We start by identifying the ant species and assessing the extent of the problem, tracing trails and looking for nest sites in and around your home.

Treat

Your Pestpatrol technician will apply targeted ant treatments, such as professional gels, baits or sprays, focusing on nesting areas and active trails to tackle the colony at its source.

Fortify

We help secure your home by pointing out and, where possible, helping to seal cracks, gaps and other entry points that ants are using to get inside, reducing the risk of future infestations.

Keep watch

We will explain what to look out for after treatment and ask you to keep an eye on usual trouble spots such as kitchens, bathrooms, utility rooms and garages. If you notice new ant activity, contact Pestpatrol to book a follow up visit.

Report

After every visit you receive a clear written report explaining what we found, what we have done and our recommendations to help prevent ants returning.

Follow up

Ant control is a process, not just a one off visit. We schedule follow up appointments where required and remain available between visits if you notice renewed activity.

Frequently asked questions

How to get rid of red ants?

Red or fire ant infestations are very hard to eliminate with DIY products alone. Home remedies like orange oil or boric acid might reduce the number of ants you see, but they rarely reach the nest or the queen. For a lasting solution, it's best to call a professional pest controller. Pestpatrol can identify the species, treat the nests directly and put a proper ant control plan in place to stop them coming back.

How to get rid of small black ants?

The most effective way to get rid of small black ants in your home is to call a professional pest control company. A Pestpatrol technician will carry out a full inspection to find where the ants are coming from and how they are getting inside. After the inspection, we will explain the best treatment options, target the nests rather than just the visible trails, and give you practical advice to help prevent future infestations.

How to get rid of carpenter ants naturally?

Carpenter ants can sometimes be reduced with natural bait made from a sugary attractant mixed with an active ingredient. The workers carry the bait back to the nest and share it with the queen and other ants, which can weaken or destroy the colony if it is used correctly. However, natural methods are easy to get wrong and often fail to reach the entire nest, so the problem soon returns. For reliable results, it is best to ask a professional. Pestpatrol can identify the nest, apply the most suitable treatments and give you advice to help stop carpenter ants coming back.

Does vinegar kill ants?

Vinegar might kill a few ants on contact and disrupt their scent trails, but it will not get rid of an ant infestation. At best you will only remove the ants you can see, and unless the nest and entry points are treated properly they are likely to return. A professional pest controller such as Pestpatrol can locate the colony, identify how the ants are getting in and create a tailored treatment plan to remove them and help stop them coming back.

Does bleach kill ants?

Bleach can kill the ants you spray directly and may remove their scent trails, but it will not solve an infestation. It only deals with the ants you can see; unless the nest and the routes they are using are treated properly, they are likely to return. A professional pest controller such as Pestpatrol can find the colony, locate entry points and create a tailored treatment plan to get rid of the ants and help stop them coming back.

How to get rid of ants in the kitchen?

Getting rid of ants in the kitchen usually needs the skill and knowledge of a professional pest control company. A Pestpatrol technician will identify the ant species, find where they are coming from and design a tailored treatment plan. This may include a mix of indoor and outdoor treatments, along with practical advice on hygiene and proofing to help stop ants coming back.

Is it safe to be in a house after a pest control treatment?

Yes. Professional products used indoors are applied at carefully controlled low concentrations that are designed to be effective against insects while remaining safe when used correctly. Your Pestpatrol technician will explain any precautions, such as keeping children and pets away from treated areas until they are dry. If you are concerned, you can also choose to leave the property for a few hours after treatment for extra peace of mind.

Why do ants keep coming back into my home?

Ants leave scent trails for other workers to follow, so once they find food or water they will keep returning to the same places. If the nest is not treated and entry points are not dealt with, new workers will simply replace the ones you have killed. Professional ant control focuses on both the colony and how they are getting in.
