What kind of scope ? Got a link to buythe problem with basting is you may not get them out of the system, and you definitely dont get the eggs off that way. I thought I had gotten rid of them back in may or so because I hadnt seen any signs of them on visual inspection with the naked eye for a few weeks, then I was away for about 5 weeks and when I got back the infestation was back in full force. Thats what drove me to purchase the scope to eradicate them. Figured it must have been a baby or a very small one i didn't. Now I see everything!
