Nemasys F is used for the control of Leather Jackets and ants. Nemasys F contains the parasitic nematodes of Steinernema feltiae. The Steinernema will seek out the Leather Jackets and penetrate them, infect them with bacteria which stops them from feeding and the Leather Jackets will quickly die and the Steinernema will continue to breed and seek out more Leather Jackets. This product is completely safe for people, environment, crops and beneficial insects. They will also control sciarid fly larvae, thrip pupae, shore fly, leaf miner, ants and black vine weevil larvae. Can be used on moist lawns and grass where the soil temperatures are above 8oC

Storage: This product is perishable as it is a live product. They should only be stored for a maximum of 2 days after receipt and must be stored at a temperature of 2-6oC.

Features & Benefits:

  • Safe for humans, pets and the environment – children and pets need not be excluded from the areas.
  • Steinernema feltiae will also seek out other pests in their soil borne stage meaning you have extra control of other pests at no extra cost.
  • They are completely harmless to earthworms which are a great natural beneficiary to your soil.
  • They can be used on a huge range of crops – turf, beds and borders, pots and planters or around trees and shrubs.
  • Nematodes have no effects on other beneficials you may introduce to your crops so if you have added other biological control products they will happily live alongside each other.
  • They give long lasting protection against soil dwelling pests so you do not need to keep buying more product every week.
  • They can be used in an organic pest control programme.
