Beneficial nematodes are a naturally occurring, extremely effective control for many soil-dwelling insects such as grubworms, fleas, ticks, termites, chinch bugs, fireants, and larval forms of thrips and grasshoppers. They are harmless to people, animals, plants, and other beneficial organisms such as earthworms.
Beneficial nematodes can be applied 2 to 4 times a year for general control; however, mid-winter is the only time to effectively control ticks and thrips. If chemical pesticides have been used, wait at least 24 hours before applying nematodes. NOTE: We carry only live nematodes which are more effective and preferable to products containing the dormant form of nematodes.
