There are many different types of ants.
Some confine themselves to your garden whilst others will come indoors, foraging for food. Most of these ants do not pose a threat to your buildings etc. but are a nuisance pest. In order to get rid of ants, one generally needs to treat the inside and outside.
There are different measures to get rid of ants – we prefer to use 2, a residual spray & a bait in the form of granules or gel. This is carried down to the nest by the workers, which results in the entire nest being eradicated.
