Helpful hint- hit'em w/ some Safer's to dry out the chitin, and then the Botanigard a few hours later. Fungus can only colonize thru breaks in exoskeleton- which will happen eventually anyway ( Lord knows I can't go a day w/o cutting myself) but you can hurry the process along.

Thrips have a subterreanean instar - if you can prevent the larvae from dropping down out of leaf tissue into the media, they will not survive to reproduce. A thin layer of DE or a physical barrier ( like a paper plate, slit to accomodate stem) will suffice.

If you do eliminate your thrips, watch out for spider mite blooms- I can't do a species ID from these pics, but some sp. of thrip will actually act as a mite predator. Ifl you're actually finding adults, without the characteristic damage of feeding larvae, you may not actually have what could be considered a " pest" population. ID of a thrip problem is almost always done by observation of feeding damage well before adults are spotted with the naked eye.

If you think you have 50-100, you have 500-1000. or 5000-10000.
