Expert Guide on How to Get Rid of Ants Yourself

If you're wondering how to get rid of ants in your home or garden, you're not alone. Ant infestations are one of the most common pest problems in UK households, especially during warmer months. In our experience, ant-related orders start climbing in May and run through to August – earlier in a warm spring.

While most ants are harmless, they can quickly become an unhygienic nuisance if left untreated. This expert DIY guide explains how to identify ants, target the nest effectively, and stop them returning – using safe, proven ant control methods you can apply yourself.

From understanding ant behaviour to choosing the right DIY ant control products, we've got you covered.

Are Ants Dangerous?

Mostly, no – but they're still worth dealing with. The large majority of ants you'll see in a UK home are black garden ants: a hygiene nuisance rather than a danger. They don't sting, but as they travel from drains, bins and soil to the food on your worktop, they can carry bacteria onto surfaces and any food left out. In sensitive settings such as kitchens, hospitals or food production, that contamination risk is the real reason to act.

Outdoors, ants are mainly a nuisance – nesting under paving can cause small stones to shift over time, and a few species will tunnel into damp, already-rotting wood. Genuine structural damage from ants is uncommon in the UK.

Types of Ants

There are more than 13,000 different species of ants around the world, but only a small percentage of these live in the UK due to the colder climate.

Most of the ants you see invading your home are likely to be female worker ants foraging for food, which they take back to their nest to feed the larvae and the queen ant.

Most ants are between 3 and 5mm in length and have three main body parts: the head, thorax and abdomen, clearly separated by very narrow waists. They also have a sharp elbow joint on each antenna, segmenting them into two parts.

Black Garden Ant (Lasius niger)

The black garden ant (Lasius niger) is the most common and well-known ant species in the UK and is comfortable living both indoors and outdoors. Despite their name, they are actually very dark brown in colour. Black garden ants like to nest under paving or in the soil along the edges of lawns. They also live inside the cracks around your house, and anywhere else they can find shelter.

Black ants make their way into your home in search of food, and because they love sweet substances, they are often referred to as sugar ants. You'll find them around honey and jam jars or feasting on the piece of cake you left out. They have a varied diet, though, and are useful for cleaning up dead insects and the larvae of flies and beetles. They may be ferocious foragers, but they're largely harmless to humans as they don't sting.

Yellow Meadow Ant (Lasius flavus)

Another common ant in UK gardens is the yellow meadow ant (Lasius flavus). These ants are often mistaken for red ants due to their orange-yellow colour, but they don't bite and are quite harmless to humans. They build large mounds in meadows and lawns and forage underground on insects and larvae.

Yellow Lawn Ant (Lasius umbratus)

Lawn ants (Lasius umbratus) closely resemble yellow meadow ants. However, they have a somewhat unorthodox way of establishing their nests. After mating, the queen kills an ant from another colony and uses its scent to take over the murdered ant's nest.

Once she has entered the nest and been accepted by the worker ants, they will kill their own queen and look after the yellow lawn ant queen and her brood instead. As the existing worker ants no longer have a queen of their own, they won't be replaced when they die off, and the nest will become exclusively yellow lawn ants.

Jet Black Ant (Lasius fuliginosus)

Jet black ants (Lasius fuliginosus) are jet black in colour, slender, and have heart-shaped heads. They are larger than black garden ants and build carton nests out of wood chewed into a pulp and combined with honeydew, forming a hard crust when it dries.

Like the yellow lawn ant queen, the jet black ant queen is unable to establish her own colony and will take over another ant colony, killing the queen and gradually taking full control of the nest.

Red ants (Myrmica)

There are several species of red ants in the UK, the most common being Myrmica ruginodis. They live in very small colonies of between 100 and 300 members.

Another species, Myrmica rubra, also known as the European fire ant, can give a noticeable sting and is fairly aggressive.

Wood ants (Formica)

There are several species of Formica ants in the UK. Formica rufa, also known as the red wood ant, southern wood ant, or horse ant, builds huge mounds of wood litter in forest clearings and pathways. Colonies can number more than 100,000 ants and collect up to 100,000 insects and larvae in a single day.

Formica fusca is another wood ant that is black and less aggressive than the rufa ant. They nest under rotting logs and have small populations. They may be polygynous (having more than one queen), but usually limit the number to just a few per nest.

Ant Behaviour

Ants are social creatures that live in highly organised communities, and they're far more active in warm weather. This is why you see them streaming into homes across spring and summer, foraging for food – and it's why our own ant-related orders build from May onwards, earlier still after a mild, early-warming spring.

When a worker ant comes across a tasty morsel of food, it releases a tiny drop of pheromone and keeps doing so all the way back to the nest. In no time at all, a long line of ants is following the trail to the latest food source. Ants are hard workers, capable of carrying between 10 and 50 times their body weight, because their bodies are mainly muscle.

Some species take care of dead and rotting wood, while others pollinate plants and spread seeds. You'll often see ants dragging a dead insect towards the nest or carrying crumbs along a pathway towards a tiny crack in the floor or skirting board.

Why Ants Invade Homes

There are several reasons ants suddenly appear indoors. Their primary focus is food, and they send out search parties from spring through summer and into autumn.

When the weather is dry, ants may come in search of water, and you can sometimes find them clustered around the rim of a tap, drinking from a droplet.

When the weather is wet, ants may head inside when their nests have been saturated with rainwater. They'll find a useful crevice in the walls of your house and move their nest indoors. You may see a long line of ants carrying their eggs inside as they relocate to a warmer, safer place.

Breeding Habits of Ants

Ants are one of the most robust and abundant insect groups on the planet, thanks to their complex breeding habits and their ability to survive in many ecosystems.

Breeding differs from species to species. Some colonies have one queen, while others are polygynous, with anywhere from two to hundreds of queens. Some colonies are small, such as the red ant with an upper limit of around 300 members. Wood ants, on the other hand, breed colonies of up to 100,000 ants.

In addition to at least one queen, each colony starts with a number of winged males and one or more winged, virgin females. These reproductive ants fly out of the nest to find a mate from a different colony for a few days around July and August. Flying away from the nest keeps inbreeding low.

After mating, the queen looks for a suitable place to build a new nest, or takes over another colony's nest, and begins to lay her eggs. In her own nest, she raises her brood single-handedly until she has a team of female workers to take care of the eggs, larvae and pupae.

Fertilised eggs become either female workers or future queens. The queen controls her colony by secreting a substance that stunts the growth of wings and reproductive organs, keeping her female workers unproductive. Once she has enough workers, the remaining females are left to develop into virgin queens. Unfertilised eggs become winged males whose sole purpose is to fly away and fertilise queens from other nests.

In some species, producing queens and males can take years. Some polygynous species send workers out to support one of their fertile queens and build her a new nest – this is known as colony budding, the establishment of a new nest without going through the mating process.

Some species have only one queen, and when she dies it means the end of the colony, as there is no queen to continue reproduction.

Ant eggs turn into larvae – cream-coloured grubs without legs – that become pupae in due course. The pupae are a smaller version of the adult ants, initially cream-coloured, but eventually taking on the same colour as the adults.

Health and Safety Risks

The main risk from UK ants is hygiene. Because they travel across drains, bins and other dirty surfaces on the way to your food, they can transfer bacteria onto worktops and anything left out. A few species can give a small nip if handled, which may irritate sensitive skin, but the common black garden ant doesn't sting. For typical UK household ants the disease risk is low – the sensible priority is simply keeping them off food-preparation surfaces.

Identifying Signs of an Ant Infestation in the House

Spotting an ant infestation early can save you a lot of hassle further down the line. As ants are social creatures, when you see one there's likely a colony not too far away. Here are some key signs.

Ant Trails and Foraging

One of the most visible signs is an ant trail. Most commonly these form the route between a food source and the nest, so a consistent flow of ants along the same path points to an established colony nearby. Ants are drawn to sweet, sticky or greasy residues, so seeing them in your pantry or on countertops is a clear indicator.

Ant Nests

Ant nests vary in appearance, but they often look like small piles of soil or dirt. Some species prefer to nest in walls or other quiet, dark places, so an obvious mound isn't always visible. Look for fine dirt, sand or earth pellets in unusual places, such as along skirting, in corners, or under appliances, as these can be signs of indoor nesting.

Damage to Buildings or Plants

Ant damage is usually minor in the UK. Nesting under paving and patios can cause small stones to shift or sink over time, and a few species will tunnel into damp, already-rotting wood such as old logs, stumps and untreated decking rather than sound timber. True carpenter ants – the wood-excavating species behind serious structural damage in North America – are rare and not established as a UK house pest, so if you spot the odd ant indoors, structural damage is very unlikely to be the cause. Some species may also disturb plants in the garden.

Winged Ants

Winged ants inside your home can indicate a colony nearby. These are the reproductive members of the colony, venturing out in spring or summer to start new nests.

If you notice any of these signs, it's worth acting promptly. Early intervention is the key to stopping a small problem becoming a bigger one.

Common Locations for Ants and Ant Nests

Ants can nest almost anywhere, indoors and out. If in doubt, watch them go back and forth between the food source and the nest. Common spots include:

Indoors

• Wall Cavities: ants can nest within walls, especially if they're damp.
• Kitchens & Bathrooms: these attract ants thanks to available food and moisture.
• Under Floors: especially in damp areas or where the floor sits directly on the ground.

Outdoors

• Soil: look for small dirt mounds in the garden.
• Under Paving: cracks in driveways or paths can hide nests.
• Decaying Wood: damp, rotting wood such as old logs, stumps and untreated decking can attract nesting ants.
• Foundation Walls: check near cracks or debris close to the house.

Preventing Ants in Your Home

An important part of ant control is stopping ants getting into your home in the first place. This is harder than it sounds, as ants are brilliant at finding new paths if their usual ones are blocked.

If you already have ants indoors, prevention alone is unlikely to fully remove them. Use these prevention techniques together with baiting and removal.

Proofing and Sealing Entry Points

Effective proofing means sealing cracks and holes around floor and wall edges with cement or silicone filler – remember, no hole is too small for ants. Follow the streams of ants to identify the nest entrance and where they're getting in, then deal with the nest (bait is most reliable) and seal the gap once activity has stopped. Sealing before the colony is under control can simply push it elsewhere.

Ant infestations outside your home may be easier to control. Depending on whether you have pets or children around, consider a deterrent-led approach before resorting to poisons. For a small, visible outdoor nest you can reach, pouring boiling water in can knock back the surface population – but take care (scald risk, and it can damage lawns and paving), and be aware it rarely reaches the queen deep in an established nest. Don't forget to check for cracks around the exterior of the house and seal them with cement or silicone.

Sanitation and Housekeeping

Worker ants, being foragers, generally prefer sweet substances. Store food out of reach, in sealed containers or the fridge. Clean kitchen surfaces and sweep floors regularly.

Outdoor Maintenance

Some outdoor ants nest under rotting leaf piles, others beneath ground-level branches. Where possible, sweep the ground to expose holes and nests. If a nest is under paving, lifting a few stones may be needed to reach it. Remember there may be thousands of ants and larvae in the nest, so simply spraying or pouring liquid into the hole may not eliminate the whole population – which is why bait, carried back to the queen, is usually more effective.

Using Natural Solutions

To help deter ants, consider wiping surfaces with a natural mixture. Several ingredients can disrupt trails and deter ants without harming children or pets, though they won't clear a nest on their own:

• Vinegar
• Citrus
• Lavender
• Coffee grounds
• Essential oils

Ant Control: Effective Ant Trapping and Removal Techniques

The long line of ants heading into your kitchen is just a fraction of those down in the nest, so don't assume that wiping out the visible ants on your counter has made a dent in the population.

How to Get Rid of Ant Nests

Once you've identified the nest, the goal is to reach the queen – kill her and the colony collapses. The most reliable way to do that is bait: ant bait stations or gel placed on the trail, which workers carry back and share with the queen and larvae. For a small, accessible outdoor nest you can also try pouring boiling water in (with care – scald risk, and it won't reach a deep nest), or a pesticide-free ant killer spray for visible ants. Some people also dust a fine, food-grade natural powder such as diatomaceous earth along trails and entry points as a gentle option – it only works while dry, so keep it to dry indoor spots and reapply if disturbed. None of these, though, matches bait for actually collapsing the colony.

Some ant species set up satellite nests nearby, so check the surrounding area for others.

Types of Ant Traps

The most effective ant traps work by coaxing worker ants to take the bait back to the nest for the larvae and queen, collapsing the colony from within.

Why Ant Baits Work Better Than Sprays

Spraying visible ants may reduce numbers temporarily, but it rarely solves the problem. This is the single most common mistake we see – people spray the trail they can see, which knocks back surface ants but leaves the nest producing more. Bait is what reaches the queen, and it's the only reliable way to collapse the colony.

It also asks for a little patience. Activity often rises for a day or two as workers discover the bait and recruit others, before numbers fall. That early spike is a sign it's working, not failing – the frustration of not seeing instant results is what tips people into spraying, which sets them back.

Ant Bait Station Traps

Ant bait stations are enclosed devices containing insecticide bait. They attract worker ants, who carry the bait back to the nest.

Sticky Ant Monitoring Traps

These sticky insect traps are designed to detect ant activity and monitor hotspots. They won't solve an infestation on their own, but they're useful for capturing wandering ants and showing you where ants are travelling. Place them along visible trails, near entry points and skirting edges, then check and replace as needed.

Ant Gel Baits

A more versatile option, gel baits can be applied into cracks, crevices and areas where ants are active, providing a discreet solution that workers carry back to the nest.

Placement and Baiting Strategies

Place traps along ant trails and near entry points, but well out of reach of children and pets. If possible – though not strictly necessary – use a variety of baits to appeal to ants' changing food preferences, alternating between protein and sugar-based baits. A typical rule of thumb is around 1 to 5 bait stations per 40m².

Safe Removal and Disposal

Always wear gloves when handling traps and dispose of used traps in sealed bags.

Ultrasonic Repellers (a helpful add-on)

Ultrasonic ant repellers can be a helpful extra layer for some homes when used alongside the basics – cleaning up food residues, removing moisture sources, sealing entry points and baiting. For best results, place them in open areas near ant activity (not behind cupboards or soft furnishings) and keep them switched on continuously.

When to Use Chemical Ant Killers

Consider chemical solutions for severe or persistent infestations where gentler methods – baiting, a pesticide-free spray, or knocking back a small accessible nest – have failed or aren't feasible. Many effective baits, sprays and powders contain some chemicals in order to work, so always check the product information carefully.

Safety Precautions with Chemicals

Always follow the product instructions and wear protective gear such as gloves and, where directed, a mask. Keep chemicals away from food areas, pets and children.

Recommended DIY Ant Control Products

For fast, effective results, the ant problems that clear up quickest – in our experience – combine three things: bait to reach the nest, a spray for visible ants, and a powder for cracks and edges. That's why our ant control kits work so well (they pair all three), and why a bait station is the single most important item if you only buy one thing:

• Ant bait stations – the priority; they kill the colony at the source
• Ant control kits – bait, spray and powder together for a complete approach
• Ant killer sprays – quick knockdown of visible ants (a support act, not the fix)
• Ant monitoring traps – sticky traps to detect and track activity
• Sealants and fillers – block access once the colony is under control

When to Use Professional Pest Control Services for Ants

When to Call the Experts

Most UK ant problems are well within DIY reach, but sometimes a professional is the sensible call. If DIY methods keep failing or the infestation keeps returning, that can point to a large or hidden nest. It's worth calling in help if a big or entrenched colony keeps coming back after proper baiting, if you're dealing with an unusual or aggressive species you can't identify, or if there are vulnerable people in the property. You can find a qualified controller through the BPCA directory.

Advantages of Hiring Professional Ant Control

Professional ant control offers a few advantages. Experts can access more potent treatments and apply them safely, and they can identify the specific species and tailor their approach, ensuring a more effective and lasting solution.

Frequently Asked Questions About Ant Control

How do I get rid of ants permanently?

You must eliminate the nest, not just the ants you see. Bait-based control lets worker ants carry the treatment back to the queen and larvae, preventing the colony from recovering.

Do natural remedies really work?

Natural methods can disrupt ant trails and deter activity, but they're usually best combined with bait stations for full colony control.

How long does ant bait take to work?

You may see increased activity at first – this is normal, and a sign the bait is being found. Most ant infestations reduce significantly within 7–14 days, so give it time before changing tack.

Are ant treatments safe around pets and children?

Always follow the product instructions carefully. Use enclosed bait stations and avoid placing treatments in accessible areas.

Final Thoughts

While ants have their place in the food chain, they can be a nuisance and, on food-preparation surfaces, a hygiene concern. If they're not causing a problem in your home or immediate surroundings, it's fine to let them be. Otherwise, target the nest with bait, be patient through the first few days, and use prevention to stop them returning. If all else fails, a professional can offer advice and a more permanent solution.
