Why Are Ants Suddenly Appearing in My Kitchen in Cambourne?

The Short Answer

The ants in your Cambourne kitchen are almost certainly workers from a colony outside the house. They have found a food source, laid a trail, and recruited the rest. The colony itself is somewhere else, and that distinction decides what works.

Why a Newer Home Is Not Immune

Cambourne was built from the late 1990s, and many homes have patios, paved paths and landscaped borders close to the walls. Those are exactly the sheltered, warm spots where black garden ants nest. A colony under a patio slab is only a few centimetres from the house.

Modern construction does not stop them either. Ants need very little room, and common weak points include:

• Gaps where service pipes pass through the wall.
• The joint between the patio or path and the brickwork.
• Door thresholds, particularly patio and garden doors.
• Gaps behind kitchen plinths and around the sink.

The Timing

Ants are most noticeable from spring through summer. As the soil warms the queen lays more eggs, the colony needs more food, and foragers go further. If the weather has just turned warm, a kitchen that was ignored last month is suddenly worth a visit.

Check These First

1. Look near the bin, the recycling box and the pet bowl.
2. Check for sticky residue on jars, bottles and the base of the kettle.
3. Watch where the line enters the room. Note the exact spot.
4. Look outside at the same wall for activity on the patio or border.

What Does Not Work Well

Shop-bought sprays and powders kill the visible ants and leave the colony intact. The common experience is quiet for a day or two, then a return, sometimes by a different route. Ant barrier lines can push the problem somewhere else in the house.

What Works

Treatment that workers take back to the nest reaches the queen and the brood, which is why it ends the problem rather than pausing it. Our ant control service in Cambourne is £240, fixed, with no call-out fee and the price confirmed before booking. Every treatment is guaranteed: if ants return within 14 days, we re-treat at no charge. For details, see the ant control cost guide.

A Quick Garden Check

Stand outside the kitchen wall where the ants appear and look down. Small piles of fine soil between paving slabs, or a steady stream of ants crossing the patio, are signs of a nest below. Cambourne gardens are often compact, so the nest tends to be close to the house. Take a photo before you call, as it saves time and lets us advise more accurately.

If you would like us to look before you decide, a pest inspection and survey costs £120. Otherwise, ring 01223 902388 or message us on WhatsApp with where the ants are coming from.
