Using Nematodes to repel Ants
Nematodes do not actually kill ants, but they have a deterrent effect, in that ants will choose to move away if you drench the ground with certain nematodes. This Nemasys product called "No Ants!" is a sealed pack of nematodes. Just mix with water and sprinkle onto the offending nests. Like all our nematode packs it should be ordered fresh, and not stored after it is open. If you have to keep it a few days before using it then just pop it in the fridge.
Nematodes can be used indoors or outdoors, and are active when temperatures are above 5°C. The optimum soil temperature is about 10°C. They remain in sufficient concentration to give good effectiveness for about 6 weeks or more.
Nematodes travel by slithering around the soil particles so the soil needs to be
kept moist. If it is hot and dry they will either shrivel and die or hide away deep
