Pests & Diseases > Ants

Ants can often co-exist without too much effect on the grower. Ants are considerable scavengers who prey on things for the liquid food which they feed to those in the nest. 

Cause

Their presence is usually a sign that seedlings are too dry and warm. 

Prevention

Where food or moisture is scarce they may enter houses or buildings looking for it. Their presence is usually a sign that seedlings are too dry and warm. They are particularly attracted to dry, easily excavated sites so will settle in rotting wood, sand between bricks or paving as well as the base of pots and tubes. 

Keep seedling tubes in the polystyrene boxes or trays to keep moist. Make sure the whole tube is kept moist. Dry tubes will form air pockets or a crust on the surface and the ants will consider this a perfect location to create a colony. Avoid having the seedlings sitting directly on the bench surface. 

Cure

Ants can generally be dealt with by: pouring boiling water down the main nest entrance, disturbing the nest so they are forced to re-establish elsewhere. wetting the area or using ant dust on the common trail to and from the source. If the infestation is severe, put containers of water under bench legs to stop ants climbing up.
