I'm wondering if anyone has had luck with homemade pyrethrum sprays? I recently had a thrip problem that I (hopefully) solved with neem oil - usually used for mites. So, I've been doing some reading, and it turns out that these cute little pyrethrum flowers in my yard pack a pretty potent punch if made into a spray. It's a pretty toxic organic pesticide. Supposed to eradicate the thrips. Although, I find the description of how it works a bit horrifying:
So, if you've had experience with the stuff, let me know. The Good, Bad and Ugly. All comments welcome.

"Pyrethrins delay the closure of voltage-gated sodium ion channels in the nerve cells of insects, resulting in repeated and extended nerve firings. This hyperexcitation causes the death of the insect due to loss of motor coordination and paralysis."
