The only bad thing about the bindweed mite being distributed by the Bushland Research Center is that it's working too well.
Supply is outstripped by demand.
The tiny mite is doing a terrific job against the weed. In one instance, a Bushland research associate put the mite in her backyard that was about 90 percent bindweed. So it did work. The main problem with the mite is that moves slowly. Mites typically don't spread unless the bindweed is mowed, or if infested bindweed is moved into a new patch.
