General information

When to use NOFLY WP™?

Apply at first symptoms of pest attack. Minimum 3 applications at 5-7 day intervals or shorter in severe infestations.

How does NOFLY WP™ work?

When spores of NOFLY WP™ come into contact with the insect pest they attach to the body and begin to grow almost immediately. Once the spore germ tube penetrates the host cuticle, fungal multiplication takes place through formation of hyphal bodies in the host body. The NOFLY™ microbe mechanically disrupts the host’s internal organs and initiates tissue necrosis. This leads to lack of feeding, inactivity and eventually death.
