Ants look simple until you try to name them. Here is how to tell them from other small insects, what their trails and nests reveal, and what to record before you ask for help.
Ants are easy to confuse with other small insects, so look closely before buying anything. An ant has three body sections, six legs, elbowed antennae and a distinctly narrow waist between the middle section and the abdomen. Most ants that wander into British kitchens are small black or dark brown garden ants, only a few millimetres long. Pale yellow-brown ants that survive indoors through winter are rarer and usually point to a warm building.
On warm, still days in summer, winged ants sometimes pour out of a crack in the patio or the edge of a window frame. These are the reproductive members of a colony leaving to mate, and they do not last long. The giveaway is the waist: an ant has a pinched one, while a termite body looks more uniform. The front wings of an ant are also longer than the back pair.
Ants follow scent trails, so a steady line of insects going to and from one point is the clearest sign you are dealing with ants rather than a stray beetle. Workers carry food back to a nest you often cannot see. Watching which way the line runs, and what it is heading for, gives a technician most of what is needed to find the source.
Small dark insects on a windowsill may be beetles, springtails or aphids. Beetles have hard wing cases that meet in a straight line down the back, springtails jump when disturbed, and aphids are soft and rounded. A lone insect wandering aimlessly is less likely to be an ant than one marching in a line. Getting the identification right matters because the treatment for each is different.
Write down where the trail enters the room, what time of day it is busiest and whether the ants prefer sweet or greasy food. A clear photo of a few insects on a pale background helps enormously. Please resist spraying the trail with a household aerosol first: it can scatter the workers, spread the problem across more rooms and make the nest harder to trace.
The black garden ant is by far the most frequent visitor, nesting in soil beneath paving, lawn edges and wall bases, then foraging into kitchens in search of sweet food. Yellow ants live in grassland and sometimes appear as winged swarms. Species that live indoors all year round tend to be paler and smaller, and they favour warm spots such as airing cupboards, heated kitchens and spaces near pipework.
Size can also mislead. Ants in the same trail may differ in size if the species has more than one worker caste, so do not assume you are looking at two kinds. A reliable identification usually comes from a close photograph, a note of colour and the nest location, which is why technicians ask for these details before suggesting a treatment.

Usually not. Flying ants are the winged reproductive males and queens of the same colonies that produce the wingless workers you see in the kitchen. They leave on warm summer days to mate, and most are gone within hours or days. Their presence does show a nest is close by.
Check the waist and antennae. Ants have a clearly pinched waist and elbowed antennae, while termites have a thick, even body and straight antennae. Winged ants also have front wings noticeably longer than the back pair. Termites are far less likely in British homes.
No. Ants are drawn by food and water in tiny amounts, and a clean home can still have a trail if a nest sits under a patio or wall nearby. Cleaning up crumbs and spills helps, but it will not remove the nest itself.
