Ant Control

There are thousands of ant species worldwide, but in the cooler UK climate the Garden or Black Ant is the most resilient species to live outdoors. Tropical ant species such as Ghost and Pharaoh's ants only survive with the warmth provided inside heated buildings in the UK. Ant problems often occur alongside other insect issues such as flies and cockroaches in commercial kitchens.

Garden Ant (Lasius niger)

• Workers 4 to 5 mm long, queens up to 15 mm long
• Dark brown-black in colour
• Nests often outdoors in soil and below paving slabs on the sunny side of buildings
• Foraging workers follow well-defined trails around food sources; sweet foods are preferred
• Mating takes place on the wing mid to late summer; males perish after mating

Ghost Ant (Tapinoma melanocephalum)

• Pale, translucent legs and abdomen, only 1.6 mm long
• Tropical species that only lives indoors in the UK
• Feeds on sweet substances and grease; nests in small spaces and wall voids
• Attracted to high moisture areas such as kitchen and bathroom cabinets

Pharaoh's Ant (Monomorium pharaonis)

• Workers 1.5 to 2 mm long, yellow-brown with brown abdomen
• Multi-queen colonies; swarming can take place at any time of year
• Each queen produces up to 3,500 eggs in its lifetime
• Deep-seated in cavities in heated buildings; often found in hospitals
• Colonies can range from a few dozen to 300,000 individuals

If you have seen a few ants scuttling around on the floor, they are probably searching for food. If the queen ant has set up her colony close to your property, this could be the first sign of a larger infestation.

• Ant nests: A nest site can look like a small pile of soil or dirt. Some species like to make their home in walls or other quiet, dark places, which are more difficult to spot.
• Ant pathways: In and out of the property. Some ant species lay down a pheromone trail to a food source, attracting other ants to find the food.
• Live ants: Large numbers of live insects indicate a problem. Ants in kitchens or food preparation areas require immediate action.

Most ants only come into your home to look for food. They are especially attracted to anything sweet and sticky. Putting in place simple deterrent measures can prevent infestations from establishing:

• Clear up food and liquid spillages immediately. Even the tiniest crumbs are enough to attract an army of ants.
• Sweep up food crumbs from under kitchen appliances and units.
• Store food in airtight containers or bags in cupboards or refrigerators. Empty fruit bowls with fermenting fruit regularly.
• Pet food: Clear up leftovers straight away and clean bowls after use.
• Block off entry points by sealing cracks and crevices around doors and window frames with silicone or acrylic.
• In the garden: Ensure all rubbish bins have tightly sealed lids.

For persistent ant problems, particularly in properties across Hartlepool, Durham, and Sunderland, professional treatment is recommended. Contact us for a free survey.

Spring (March to May) - Colonies activate: As soil temperatures rise above 10°C, ant colonies that have overwintered underground begin foraging above the surface. Black garden ants are the first to appear, sending scouts into kitchens, conservatories, and ground-floor rooms across Hartlepool, Sunderland, and Darlington. Watch for: trails of ants following edges of worktops, windowsills, and door frames; small mounds of excavated soil appearing between paving slabs and along path edges; and ants clustering around pet food bowls or spilled crumbs.

Summer (June to August) - Peak activity and flying ant events: This is the busiest period for ant call-outs. Colonies are at full strength and foraging intensifies. Flying ant day (the annual mating flight) typically occurs in July or August, when winged males and queens swarm from nests across entire streets simultaneously. Watch for: large numbers of ants trailing through kitchens and utility rooms, winged ants emerging from cracks in paths or around air bricks, and Pharaoh's ant activity in heated healthcare and hospitality premises which remains constant year-round.

Autumn (September to November) - Activity declines outdoors: Cooler temperatures reduce outdoor foraging. Newly mated queens burrow into soil to establish colonies that will emerge the following spring. Indoor ant problems typically subside, though Pharaoh's ants in heated buildings across Middlesbrough and Stockton continue unabated. Watch for: a sudden drop in visible ants outdoors (normal seasonal behaviour, not a sign the colony has gone), and any continued indoor activity which suggests an indoor nest rather than an outdoor colony foraging inside.

Winter (December to February) - Dormant period: Garden ant colonies are dormant underground and require no treatment during winter. However, this is the ideal time to carry out preventative work: seal gaps around pipework, fill cracks in external walls, and fit brush strips to external doors. Watch for: any continued indoor ant activity during winter, which almost certainly indicates Pharaoh's ants or an indoor nest rather than a garden species. Pharaoh's ants in centrally heated buildings such as care homes and food businesses do not go dormant and require specialist bait treatment at any time of year.

• Clear away food debris and clean food preparation surfaces before the visit. This makes bait more attractive to foraging ants.
• Identify and note where ant trails are most active (along skirting, under appliances, around plug sockets, near food).
• Do not apply any DIY ant killer spray before the visit. Residual insecticide repels ants away from treatment areas and reduces effectiveness.
• If you have applied spray previously, inform the technician so treatment can be adjusted.
• Move pet food bowls away from active ant trail areas.

In the commercial environment, ants are more than just a nuisance. They can cost you money and harm your reputation. This is particularly true for organisations that handle food or need to keep areas sterile.

Premises at risk: Pubs and restaurants, hospitals, offices, hotels, warehouses, and other buildings that store food and water across Darlington, Stockton, Middlesbrough, and the wider North East.

Business Impact Without Adequate Control

• Waste: Contaminated food and products must be thrown away, costing money and resources
• Health risk: Infestations in hospitals and care homes can spread pathogens (Pharaoh's ants) and alarm patients or residents
• Reputation: Customer confidence suffers, directly impacting profits

A tailored control service combats ant issues with the most appropriate and effective methods, whether the infestation is within the premises or around the exterior. Food businesses and education settings should arrange regular inspections during the active season.
