Spinosad is the active ingredient in Elector PSP. When I was choking on the price to get 8 oz of that I looked for the active ingredient in other options. There are quite a few but I was unsure of the math and of course had lice at the time so didn't want to risk doing it wrong.Hold onto that cattle powder because I think you will have a hard time getting more. In the future, remember that you can use any form of ivermectin for lice, mites, and large roundworms, though here in the US I think many vets will suggest a 2-8 weeks egg withdrawal.
You can probably use any liquid or powder from the garden center that contains carbaryl, permethrin, or spinosad, but you would have to figure out the correct dilution, and I would be happy to help you with that.![]()
If you did the math for another Spinosad product I'm sure there are a lot of people who would love that information!
