Trichogramma Wasps vs. Squash Vine Borer
Hi, I’m interested in trying parasitic wasps this year for my garden nemesis – the squash vine borer. The instructions say to “release” them every other week. Do you send 1 square every other week or do three squares arrive in one shipment. If so, what makes on the square that has been put in the garden hatch, while the others don’t?
