My wife always says I’m a bad communicator, they didn’t knock it out over night but it was actually more than one bag over a couple weeks time from purchasing and getting to the bottom of the stack.How sure are you that your varmints don’t have striped tails and masked eyes? Having a hard time imagining how many mice it would take to eat 50 lbs of feed in one night.
many years ago one of the neighbors about a mile from me got the bright idea to start mixing his own feed - grains and round bales in a giant mixer then dump it on the ground for feeder steers. The land he was leasing was not cleared - lots of cover.
And, he did not bother to fence out or barricade the grains. At first, the wild hogs trailed behind the cattle while he dumped out feed. However very quickly they found the buffet source and the wild hog population exploded. He finally figured it out and started using the hay bales to block access to the grains. The good news - the hogs stayed out of our place until he went out of business 2 years later. The bad news - that's when they became my problem.
Cats and traps are the most effective on rats. Bigger traps and dogs are more effective on larger vermin.
