I just googled thrips images. I have looked with a magnifying glass, or I wouldn't see them very well... I worked at a greenhouse when I was younger and some insect was biting me. I finally caught one and asked the owner, he said it was thrips but that I was nuts if I thought it was biting me. Well, that's how I figured out that they were here. I kept getting little bites. Not since I sprayed, but I'm on the hunt for them, now. I'm wondering what other means of control people have used until I get them outside (The neem kind of stinks).
