Note: This is a re-post but contains important information on use of DDVP (dichlorvos) with mite sachets. (See point 4!)
In 2017, I had an interaction with a grower where their long-standing biocontrol program for thrips suddenly seemed to be failing. After a (too long) investigation by myself, the grower, and consultants, we found out the horrible truth: their predatory mites were being MURDERED (Duh dun DUHNNN!)… By improper storage.
This post focuses on all the ways YOU might also be guilty of mite murder, and how to make sure your mites are still alive and kicking in those little sachets.
