Advice on identifying and removing ants from your home and garden.
There are 41 different species of ant living in the UK. The one that causes most problems for people is the garden or black ant Lasius Niger.
Black ants usually nest outdoors in lawns, flower beds under paving stones and in walls. Although they are not a health hazard, they can be a nuisance.
They enter homes in search of sweet foods and get in through small gaps in masonry, doors and windows.
Ants are not just pests. They also feed off insects and act as scavengers in the garden
Treat ants with crawling insect insecticide. Apply a residual insecticide to the entrance of the nest and wherever ants have entered your home.
Inside your house, put insecticide behind the sink unit, skirting boards, around doors window frames, wastepipes and other pipes.
Try to create a band of insecticide the ants have to cross to enter your home. Make sure you also apply the insecticide to small cracks and crevices.
To make sure you get rid of problem ants you will need to find their nest.
Follow the ant trail and look for small entrance holes in the ground surrounded by small piles of fine earth. This is possibly be the nest which will need to be destroyed.
