ruthless efficencey and ease of use is the key to sucsess my friend
i use them at work, surely a hedge trimmer would be better? but fair play, i bet it blows the rats out the holes!!
ive got loads of them we were thinking blower but if you blow too much down the hole you end up digging to dead rats it is more of an art than people think
my mate uses a blower, hes got the exhaust linked to the blower pipe with a downsizer bit on the end, imo i prefer my strimmer, you get that low sitting smoke that isnt being pushed through, it sits there instead, the rats hate it!!
