Biological Control
Ant Nematodes
The parasitic nematode, Steinernema feltiae, can be used as a non-chemical control of ants.
When to treat
April to September/October. With severe infestations the treatment may need to be repeated.
Soil temperature must be at least 10°C.
How to treat
Best applied in the evening or in dull, cloudy weather conditions, avoiding exposure to bright sunlight. It is vital to apply to a moist lawn or border as the nematodes are unable to move in dry soils.Mix the nematodes in 2 litres of clean water, stir, dilute further to 20 litres and apply immediately using a watering can.
Water again and keep the soil moist for 14 days.
The pack of 5 million nematodes will treat up to six large nests. The lawn is safe to use straight after application.
Storage
The unopened pack may be stored in a fridge up to the shelf life shown on the package, usually 1 to 2 weeks. Once opened, the entire pack contents should be used immediately
