Like something out of a horror film, the army of purchased insects sense the trouble-makers and bite their head off as they emerge…. And just like that, my greenhouse problem is solved.
In the Beginning
Speckled leaves on my strawberries make me think of spider mites, but I am wrong. When I tap a leaf with tell-tale speckled leaves, I catch three white immature thrips on a piece of paper.
Thrips move slowly, crawling or sometimes hopping but never really flying. They fall easily on the piece of paper I hold below the leaf. Whiteflies are a brighter white and they fly quickly as soon as a leaf is touched. I do not have whiteflies.
My immature thrips are the size of a 12-point Helvetica lower case “e” on the recycled paper I use to catch them and they are a serious bother on my strawberry plants.
