The Mice Ate My Homework!!

OK, so this is a first in all my years of building…..

Back last winter, I ordered an IO-540 Baffle Kit from Van’s for the Rocket project because they were in stock, and I knew I’d eventually need it. The box came, I opened it to make sure it had parts in it, folded over the flaps to close it and put it on the shelf. Today I was walking near the shelf, and there was a PILE of shredded white packing paper on top, bulging out of the opening. Uh…oh…. The neighborhood has been having a field mouse problem this year! If opened it up, and sure enough, out popped Momma Mouse who dove under the workbench and disappeared. Bait traps were set. But she abandoned her six little wriggling young-un’s to their inevitable fate. I found them wriggling around in the plastic bag that has small parts and hardware.

Careful unpacking showed not damage except some “soil” - which was washed out and neutralized - and some gnawed rivet bags - that’s OK, I have LOTS of rivets of all sizes. Mice went their way to the place all wild animals eventually go - just quicker. The kit went back into the box without the packing paper - and I sent a note to Greg at Van’s begging for a new set of drawings - apparently Momma Mouse was interested enough in the Van’s assembly process to have chewed her way through most of the pages….

Lesson learned - if you have ANY chance to hosting little furry critters in your shop, remove ALL packing material when you get a box. The parts will sit on the shelves just fine without it, unless you are worried about earthquakes shaking things up.

I know…Pictures, or it didn’t happen….

Dang! They really did a number on that paper. Seems like it would take a mouse forever to chew up that much paper!

I'm in a never ending battle with mice. I have 8 bait stations outside around the house and 8 outside around the hangar along with a dozen snap traps. On average, I catch about 15 mice each month. The mouse problem is kind of an obsession with me. I have wireless cameras set up at several of the mouse traps so I can monitor their activity. There are mice running around every night. Thankfully, in the 18 months we've lived here none have been found in the house or the hangar. Oh, I have traps and a camera under the house too. Just in case.
 
For years I lived in a kind of detente with the mice in my storage barn, then a few years ago they ate an outboard motor. It was game on. I used every kind of bait station and trap that I could find in the hardware store or build off YouTube. Then one day, the cameras in the storage barn showed a couple of cats overnight seeking refuge. I started feeding those cats and providing them a heated shelter and heated water in Minnesota winters. Since then, it's been a parade of mouse and chipmunk carcasses in the barn, and those cats will leave at least one dead mouse on the house doorstep every day. Carnage, I tell you. My wife feeds them dry and wet food every day. Heated water dish. Heated cat house. And they earn their keep every day. I haven't set out a trap in 4 years.

I should clarify…these were feral cats that just showed up, probably brothers. They had no chips. First thing we did was get them to the vet for shots and neutering, and they see the vet annually. I’m not a cat person, but I do admire their work and am happy to host them.

You could try eating them :)
 
Wait until they decide to decorate their nest with the red nylon threads from your parachute case, and the gray felt from your fuselage cradle.
 
Bet you have a 5 gallon bucket, hinge pin, beer can, and some peanut butter in the shop. You can draw a cat on the side of the bucket so the feline lovers won’t feel slighted. Your biggest challenge will be to keep the lab from cleaning the can.

Another minor deterrent is a radio. Mice don't like it when people are around, so a radio left on 24 hrs. will sometimes keep them away. Works in my shop.
I can also highly recommend the Eastern Ratsnake,

Pantherophis alleghaniensis

or its local equivalent. An incredibly efficient mouser, and fun to watch. We prize them as neighbors, and occasionally have to wait patiently for them to climb down from aircraft wings. 🤣
 
We went the feral cat route years ago, but for snakes rather than mice/rats. I worked my way up to a population of about 10 cats that stayed at my house but roamed the neighborhood, I controlled the population by the amount of food that I set out. In 10 years we've seen one snake, it's working.

Snakes and cats won't happily cohabitate. In a fight it's about 50/50 with a good rattlesnake, but the cats breed faster.

Talk about a win-win!! I hope you gave them suitable aviation-themed names.

Yep. I try to be highly selective about snake killing. My place has a significant population of rat snakes, black snakes, and southern watersnakes. Unfortunately, we also have cottonmouths, copperheads, and rattlesnakes. But no mice!

This appears to be the key. An acquaintance in the pest control business told me that cat mousing activity drops off substantially if you even slightly overfeed the cats. They’ll just occasionally chase mice for fun at that point. I’ve recognized this same effect in myself; my hunting and gathering activity declines precipitously in the presence of a Wendy’s or Taco Bell.

For whatever reason we don’t seem to get the poisonous ones around the hangars. I’m a lawyer, so my theory is that venomous snakes give me some distance as a professional courtesy.
 
I like the idea, but our Lab probably wouldn’t buy into it….in fact, she’d probably invite the mice to hang out with a beer and give them more packing paper…..😀
We have three Golden Retrievers. They are best buds with one of the cats and it's common to see them wrestling around with each other. Every morning he's waiting on the step (with morning gift), comes in for breakfast and to play with the dogs, then back out. The other cat is socially inept. He loves my wife, tolerates me, but can't abide the dogs. They give him a wide berth.

I think that's true, but my wife is unmoved by the concept. At any rate, the mice are under control so I don't interfere with the cats' feeding schedule.

My wife has seen a couple of short-tail weasels back there on the video feeds. I tried hard to cultivate that relationship because they are great mousers but the interactions with the cats were a bit contentious. We've had raccoons and skunks try to set up shop, but wife wasn't having that. Noisy fights with the foxes were a nightly event for awhile but in all cases, she has ultimately prevailed on the cats' behalf. We have seen bears stick their noses in the cat door but that's not common. Just as well.
 
Beat This ...

I hangar at a farm strip in rural California, and have always (50 years+ now) had a mice problem. My all time record for "catches" is 31 in ONE weekend - ONE! All on "sticky" traps, so they wouldn't die and stink up the walls.

YMMV - But I hope not to this degree.

PS - Also had one ride along as a passenger once ...

Here is my FI/MC (Feline Inspector/Mouse Catcher) inspecting the ADS-B antennae installation. ❤️ He spends a lot of time in the Kitty Playroom (aka hangar) and leaves all the furry beasts he catches in various stages of disassembly in one place in the hangar! 🤣 😂

If you want more ideas for mousetraps, do a search for "Mousetrap Monday" on YouTube. They review various mousetrap designs. i particularly like the Mascall trap from France in the (I think) 1700's. Very effective.
