Varmitgetter Component System {The Varmitgetter Rodent Blaster}- We have found the component system is better for larger animals such as groundhog, prairie dogs, rabbits even badgers etc.etc. Varmitgetter has simplified the technology and made it more affordable; we made the electrical line and gas line separate, these fit on all existing VG units out there So the gas line is never in the tunnel the same time the explosion goes off.
