These insects go through rigorous testing with USDA to ensure they will only cause damage to the intended target weed species.
Biological controls are available for the following weed species; Dalmatian toadflax, diffuse and spotted knapweeds, Russian knapweed, Canada thistle and common St. Johnswort.
