Bindweed Gall Mites for Biological Control

A Michigan homeowner seeks sources for bindweed gall mites (Aceria malherbae), a biological control agent for field bindweed.

Current Availability

Research programs at Texas A&M, New Mexico State, Kansas State, and Colorado State have studied these mites, but commercial availability remains limited. They're not yet widely carried by mainstream biological control suppliers.

Search Strategy

• Search "bindweed gall mites for sale" or "Aceria malherbae suppliers"
• Check specialized biological control companies (e.g., Arbico Organics, Rincon-Vitova)
• Contact your state's university extension — they may know of regional distribution programs

Alternative Management

While waiting for biological controls, persistent mechanical removal, smothering with heavy mulch/landscape fabric, and targeted herbicide applications on regrowth can suppress bindweed.
