You see that's great , the farmer can see the dead mole if he wishes or any client for that matter,,,,,,,,,,,,,however a dead mole doesn't realy mean a lot weather it's 1 ,,, or 1000,,,,,
The real test that the job is finished is the lack of mole hills,,,,nothing else. No mole hils ,, no moles. Simples
I also believe the gas is very infective against moles,,, the gas itself is fecking lethal ,,, no dowt about that,, it's just it's application in a pellet , a d the fact the gas doesn't move far from the actual pellet..
Far better with traps
