You almost killed me with your frq which means they work:) Not sure if I killed an adult or just some small one(s), but I got strong response at frq 13389. I added a few more minutes to your script, I do not know why but I have a feeling that my parasites are quite resistant and short rifing do not much to them. At frq 13392 something hit my brain, I thought I was going to faint, not sure what that was - Hg, Pb or something else. Frq 13396 brought pressure feeling to my ears.
