05 June 2018: Self help advice: black ants

Black ant nests can be large and typically contain between 4000 and 6000 ants. The colony has a single queen that can live up to 15 years. During July and August, new queens will be produced and will then to start their own colony.

They’re particularly attracted to the scent of sugar and grease and they don’t sting. One successful ant will be able to communicate information to their co-workers using pheromone trails, which could lead to huge numbers of worker ants invading and contaminating human foods, if it is accessible and allowed to do so.

Treatment actions:

  • Can be controlled with insecticidal baits
  • Can take up to two weeks to control
  • Do not remove baits
  • Don’t use additional products such as dusts or aerosols as well as the insecticidal baits, as they can affect the treatment process
