Wait till dark and they are all home, large garbage bag fitted around nest and spray raid inside before securing bag around limb/ zip ties, string etc. cut the limb . Place in a safe area for a few days.
I really like the immersive scopes for pest control and squirrel hunting. Optics warehouse in the uk has a nice selection. They carry other scopes also.
Heart / lung shot with a mid power gun ,caliber of your choice and sometimes they don’t spray. Make sure not to hit the shoulder. Head shot and it will spray every time.
Have the k1’s in 22 & 25. Tiapan vet 1’s same calibers.Both are great for squirrel hunting and taking pest birds. Birds out to 70 raccoons at feedlots out 50. Closer is always better with pellets lol.
