Mites to treat bindweeds #911731
Asked July 28, 2025, 1:42 PM EDT
I’m reaching out to inquire about the use of biological control methods—specifically mites—for managing bindweed infestations in our community. We are currently evaluating sustainable and long-term solutions, and I understand that certain species of mites have shown promise in suppressing bindweed growth.
Would CSU be able to assist with identifying appropriate mite species, sourcing them, and possibly guiding us through the process of implementation and monitoring? We are especially interested in any research-based recommendations or existing extension programs that support this kind of biological control.
Please let me know if this is something your team can assist with or if there’s someone you’d recommend we contact.
Thank you for your time and support.

Hi Angela,
There are bindweed mites that you can purchase from the Colorado State Insectary: https://ag.colorado.gov/conservation/biocontrol/field-bindweed
However, they are only useful in certain situations. They work best on non-irrigated areas. If you have any areas that get regular water from sprinklers, the bindweed mites will not be effective. Further, they do take years to work - it's not a quick process.
Depending on your levels of bindweed and your expectations, using herbicides may be an option - these can be used initially and then you can resort to cultural (i.e. mulching) and mechanical (pulling, hoeing) measures.
