What is ant pest control?

Ant pest control is the process of identifying, treating and preventing ant infestations in and around your property. While a few ants in the garden are usually harmless, a full ant infestation inside a home or business can quickly become a serious problem.

Ants are persistent insects. They follow invisible chemical trails to food sources, can nest inside walls and beneath flooring, and a single colony can contain hundreds of thousands of workers. Without professional treatment, ant infestations rarely resolve on their own.

At Acorn, our pest control specialists carry out a thorough inspection of your property, locate active nests and trails, and apply targeted treatments that deal with the infestation at its source rather than just the ants visible on the surface.

Common types of ants found in UK properties

Black Garden Ants

The black garden ant (Lasius niger) is the most common ant species found in UK homes. They are most active between April and September and often enter kitchens, bathrooms and storage areas in search of food, creating clear foraging trails and becoming a serious nuisance.

Pharaoh Ants

Pharaoh ants are small, pale yellow ants often found in heated UK buildings such as hospitals, care homes, restaurants and food production sites. They can spread bacteria, including Salmonella and Staphylococcus, and usually need specialist baiting rather than standard spray treatments.

Roger’s Ants

Roger’s ants are an introduced species occasionally found in heated buildings across the North of England. They are frequently confused with pharaoh ants and similarly challenging to eliminate without professional expertise. Improper treatment can split the colony, spreading it further through a building and worsening the infestation.

Signs you have an ant infestation

Recognising the early signs of an ant infestation allows you to act before the problem escalates. Here is what to look out for.

Large numbers of live ants

Seeing a trail of ants moving in an organised line, particularly in your kitchen, bathroom or near food sources, is a strong indicator of an active infestation. If you are seeing large numbers of ants regularly rather than occasional stragglers, the colony is likely well established nearby.

Ant pathways through your property

Many ant species lay down invisible pheromone trails between their nest and a food source. You may notice ants following a consistent route along skirting boards, behind appliances or across worktops. These trails indicate that ants have established regular access routes into your home or workplace.

Nest sites and soil mounds

Small mounds of fine soil or debris near the base of exterior walls, in garden borders or between paving slabs are common indicators of nesting activity. Some species nest inside walls or beneath flooring, making them harder to locate without a professional inspection.

Flying ants emerging from inside

Seeing large numbers of winged ants emerging from within your property, rather than from the garden, is a strong sign that a mature colony has established itself inside the building. Flying ants are reproductive males and queens preparing to leave and start new colonies.

Contaminated food and packaging

Finding ants inside food packaging, around pet food or near unsealed containers suggests an established foraging route into your property. Food contamination by ants is a particular concern in commercial food businesses where hygiene standards are subject to inspection.

Our ant pest control treatment process

At Acorn Environment Services, we do not believe in a one-size-fits-all approach. Every ant infestation is different, which is why we follow a structured process designed to identify the species, locate the source and apply the most effective treatment available.

Step 1: Survey and species identification

A qualified pest control technician will visit your property to carry out a thorough inspection. We will identify the ant species, locate active trails and nest sites, and assess the full extent of the infestation. This stage is critical because different species require different treatment methods, and an incorrect treatment can make certain infestations significantly worse.

Step 2: Targeted treatment programme

Based on our findings, we apply a targeted ant treatment programme using the most suitable method for the species, infestation level and property type. This may include residual insecticide, insecticidal dust, gel bait or perimeter barrier treatments. For pharaoh ants and other fragmentation-risk species, we use specialist baiting to reach the queen and colony without disturbing the nest or causing splitting.

Step 3: Written report and prevention advice

After every treatment, we will provide a full written report detailing what was found, what was used and what further action is recommended. We will also give you guidance on preventing ants from returning, including advice on sealing entry points, food storage, waste management and garden maintenance. Follow-up visits are available if required to confirm treatment success or apply additional measures.

If ants are causing mess, damage or disruption, our NPTA-accredited ant pest control team can help. We’ll assess ant activity, recommend the right approach for your building and risk areas, and agree next steps to keep them away long-term.

Why DIY ant control rarely works

Supermarket ant killers and over-the-counter products kill the ants you can see but almost never deal with the nest. Worker ants represent only a small fraction of a colony. The queen, who can produce thousands of eggs per day, will remain deep inside the nest, unaffected by surface treatments.

Without eliminating the queen and the colony structure, the infestation will return within weeks. Professional pest controllers have access to regulated products and application techniques that are not available to the public. They also have expert knowledge on ant species and how to apply the correct treatment effectively.

Attempting to treat a pharaoh ant infestation with off-the-shelf sprays is a common mistake. The chemical disruption causes the colony to split and relocate, spreading the problem to new areas of the building.

Frequently asked questions about ant pest control

 

How long does a professional ant treatment take?

Most residential ant treatments take between 30 minutes and one hour to complete. Larger commercial properties or more severe infestations may require longer visits or multiple treatment sessions. Your technician will give you a time estimate before work begins.

How soon will I see results after ant treatment?

For spray and perimeter treatments, ant activity typically reduces within 24 to 48 hours. Gel bait treatments work more slowly, as the bait must be carried back to the nest by worker ants, but colony collapse usually occurs within one to two weeks of initial application. Your technician will advise you on what to expect based on the treatment selected.

Is ant treatment safe for children and pets?

All products used by Acorn are approved by the relevant regulatory authorities and used in line with safety guidelines. Your technician will advise you on any precautions to take, such as keeping children and pets away from treated areas until products have dried. We are happy to discuss specific safety concerns before any work begins.

Will ants come back after treatment?

Professional treatment significantly reduces the risk of reinfestation. However, ants from neighbouring properties or gardens may attempt to enter again if entry points are not sealed. Our technician will provide specific proofing advice and practical guidance on food storage and waste management to minimise the chance of a repeat problem.

Do you treat ant infestations in commercial properties?

Yes. We work with a wide range of commercial clients, including restaurants, food manufacturers, warehouses, care homes, hotels, schools and offices. Commercial ant infestations can have serious consequences for food safety compliance, business reputation, and insurance validity. We can even provide ongoing pest management contracts for businesses that require regular monitoring and treatment.

How much does professional ant pest control cost?

Treatment costs vary depending on the size of the property, the ant species involved and the extent of the infestation. Contact our team for a free, no-obligation quote. We offer competitive and transparent pricing with no hidden charges.

Do I need to prepare my property before the technician arrives?

Before treatment, we recommend clearing clutter from areas where ants have been seen, emptying kitchen cupboards in treated areas if requested by your technician, and ensuring pets are kept away from treatment zones. Your technician will provide any specific preparation instructions when your appointment is confirmed.
