Ant Advice

Are ants a problem?

Garden ants can find the smallest of cracks in buildings, and if the locate a source of food within the building they communicate this to other ants and then lead them into the building to feed. During the summer, the flying stages of the ants may be seen emerging from the nest in large numbers. This event normally lasts for only a few days.

How to control them

Remove the food sources, i.e. ensure that sugary foods are kept in sealed containers and that all food and drink spillages are cleared up immediately.

Some in insecticides are applied directly to the ant nest. If the nest can be located (usually on the outside of the building) it may be destroyed by pouring a kettle of boiling water over it. This is advised for problems on a ground floor outside area only. If the nest cannot be found, an insecticide may be used along the cracks and crevices where the ants appear (e.g. skirting boards) and this may provide a ‘barrier’ against them. Obvious holes in the exterior of the building should also be sealed using a commercially available sealant.
