Don't most serial killers start off killing and torturing insects and small animals as kids?
I haven't messed with the once-a-year chemicals, mostly do to the expense and it's unlikely to be affective for more than a few months. Its outside, mid to upper 90's during the day, high humidity, and torrential rains during huricane season. These are the worst posable conditions for a long term chemical solution. Very skeptical about the claims. Neighbors say more like a few months. Chemicals leftover from last year aren't as effect as they were when first bought, and I store them indoors in sealed containers (not just fold over the top of the bag...).
Anyway, could find the piezo element I was looking for, but did find several 3-wire speakers. Never figured out how to use them. I've got a box ful of piezo tweaters I can rip the element out of, just want a lower power one, oh well. Unfortunately, I've gotten pretty good at killing mounds. All the ones I found after mowing my lawn seem to be dead, and nothing new and active. Only been a few days, takes a while to get the new home in order. Maybe this weekend I'll have a test subject.
