Elimination of the problem will vary according to soil and weather conditions.
Fire ants migrate after a rainfall, and so do the nematodes.
Mounding will occur after a rain, but will deplete in a week to ten days if there are enough nematodes in the soil. Although the scavenging habits of the fire ants are inhibited immediately, it takes 2-3 weeks for field mounds to die out and up to 2 months for colonies around trees to die out. When a colony is treated with ANTidote nematodes, members of the colony become infected, regardless of where they are mounding. Flea infestations die out in 5-10 days. This product combined with other products and procedures will provide a once a year pest control service.
