Ecomask® Beneficial Nematodes (Steinernema carpocapsae)

Ecomask® is our recommended biological control for fleas and is especially well suited for hot and dry climates, where other nematode species may be less effective. Containing Steinernema carpocapsae, Ecomask targets surface-dwelling and mobile insect pests, making it ideal for lawns, landscapes, gardens, kennels, and agricultural settings with persistent flea pressure.

Ecomask Spray is easy to apply using the Nema-Jet Sprayer, watering cans, pressure sprayers, or injection systems, allowing for flexible use across a wide range of environments. These naturally occurring, insect-parasitizing nematodes actively seek out and infect pests, providing powerful, chemical-free control that integrates seamlessly into IPM programs.
