"Smaug"You probably live in a good place, if there's a bounty on coyotes. I'm betting there's no bounty, but no restriction either, if you have permission, and if the pellets don't leave the property.
I think you should charge just enough to cover air and pellets. Be a good neighbor, let the word spread, and maybe you just won't ever run out of a place to pest.
Make sure it's legal first though, or you'd just be walking into a trap, when the word eventually got to a cop or game warden.
Ranchers and farmers really stand a lot to lose from these varmints. I don't know how much it costs when a steer or horse breaks it's leg from stepping in a hole, but I bet it is hundreds of dollars, just for the vet bill.
Wyshadow and I have hunted a ranch that lost a Bull costing $3,000.00 and a year without new calves resulting in thousands of lost revenue. word is getting out as Mena wiped out a colony. But, ranchers are paying people to plow the holes over (while killing the prairie dogs at the same time) which makes it harder to recolonize the area. We are happy to do it for free. Getting reimbursed for the cost to replace the pellets would certainly be welcome!
You might just asked them how much would they pay to get rid of the prairie dogs. Once you have a reputation (hopefully a good one), you could raise your fee. Might be a good idea to do a few homes for free and ask them to be a reference. Just a thought.
