I not doing good either - have chipmunk, starling AND pigeon fever. My PCP prescribed topping off my PCP and pre-loading every available magazine -- and wait them out ... Hope he's right .. who knows what he charged me .
Regarding lights - if your budget allows it take a look at the OdePro KL52 Plus. It had 3 interchangeable "bulbs", green, red and IR. Includes batteries, scope mount and more. Get all of them rats !!!
Airgun Evolution - don't miss his older ones in the abandoned buildings - certainly sparked my interest in pesting.. Later on toads, iquanas and more. Educational and time well spent..
