Welcome to Sierra Biological!

Sierra Biological started life by rearing and supplying growers with parasitic nematodes - naturally occurring biological control agents that attack pest insects in the soil. 

Unlike some producers that use only in vitro methods, we have always reared our nematodes on intact insect hosts. This allows the natural host-finding behavior of the nematodes to be expressed and helps ensure a quality product.

Sierra Biological has now expanded its activities to embrace the production and supply of a wide range of other naturally occurring biological control agents for insect and mite pests on a variety of crops.

From our base in rural upstate New York., Sierra Biological provides biological control agents to commercial growers throughout the Eastern USA (from Minnesota in the north to Louisiana in the south).

Aided by a network of dedicated IPM consultants and distributors, our customers include producers of greenhouse ornamentals, vegetable crops and now Cannabis sativa. 

We are always excited to hear from new growers wanting to adopt a pest management program based on biological control! We are happy to work with you to build the best strategy to meet your needs: just contact us for help getting started!
