The constant monitoring, baiting, and resetting. There are days at a time that I don't feel like going outdoors.What is wrong with traps
When I sold our hogs, I made the mistake of parking the feed grinder in my shop. After the rats cleaned out all the feeders, they moved to the shop and literally cleaned the grinder. They were so bad that you could smell rat urine when you opened the door.
I set traps. Traps disappeared. I finally started wiring 'em to transmission gears and other heavy metal parts, but there were so many rats that I wasn't making a dent in the population.
So... I put out antifreeze in shallow pans (this was back in the '90s), and they were completely gone in a few weeks. Anti-freeze has been my rat control ever since, until recently when mfrs put stuff in it to taste bad.
So, here we are. :/
