Hello Y'all.

I know Pyrethrum with PBO is a no no. But pure Pyrethrum is very effective on ant hills. Kills roaches in the house, etc. I also know Howard is against it. But can anyone tell me why? Is Pyrethrum by itself so dangerous? I use it sparingly. Sprinkle like salt/pepper on mound. Two 7.05 oz containers lasts me all summer. One outside and one inside. And the inside one get used outside too. So, what I'm saying is that for $20, I'm good for the year. I tried using orange oil, and that is too expensive for the number of ant hills treated per bottle. So give me some comments

about your experience with "Pure Pyrethum".
