Thanks so much Deesmiles! After looking at additional images for the different stages (like the ones found at http://ropeworms.com),
I'm convinced that's what they are since I've eliminated ones identical to these other images.
If only I could find effective Rife frequencies - I'm sure the Coil machine would take care of them.
I sure wish Newport could dowse for an effective frequency(s).
If you are aware of any effective additional strategies in eliminating these (other than what's described in the link you already provided), then I would be very appreciative.
