Ants can be more of a nuisance than a pest in the garden and when you've got more than a few to move on - you may have a large lawn or plenty of pots and containers - then our Nemasys 50 Colony 'No Ant' Nematodes will help evict the ant squatters. This nematode-based treatment doesn't kill the ants but they find the presence of the microscopic worms intolerable and will abandon their nests in the lawn and set up new residence a good distance away - leaving your lawn, house and garden an ant-free zone.

The Nemasys 50 Colony 'No Ant' Nematodes must be used in one application and for smaller ant colonies, we supply a smaller Nemasys 16 Colony ‘No Ants’ Nematode.
