I use permethrin. It is way less expensive and works. It doesn't turn to clay after sitting on the shelf for quite a long time. Good luck...Yes, I remember reading some members who live in hot, humid areas especially noticed they needed to use a more frequent schedule to keep on top of worms. Your birds should feel much better soon!
One thing I'll pass along about the Elector PSP: I just learned the other night that it has a tendency to clump up when it separates between uses. I hadn't used mine in a while, and it is extremely gunky - like clay!I found some info from a seller:
"Elector does separate and settle over time. The quality of the active ingredient does not degrade. The manufacturer recommends shaking well to recombine the solids into the liquid. If the container is full, pour out 2 or 3 ounces and set it aside. That will make room in the bottle to shake the contents more easily. Shake until the contents are combined. Then, return the amount you set aside back into the bottle. Shake it well again.
Store the bottle with the cap on tight and re-shake it every 3 or 4 months to prevent the settling problem from recurring."
Hopefully you won't run into a problem, though. And some people might be using theirs much more frequently than I, or may be using more of it than I do for my tiny flock, so that they don't have a problem with it. Just passing it along as an fyi!
