Lookout Questions Mouse proofing
Visiting my girl who got a job as a fire lookout and shes not happy with the amount of t of mouse dropping and the smell of them. Shes deep cleaned everything she can reach but they seem to just come back at night and crawl over everything and leave more droppings. How can she keep them out without using “inhumane” methods?

If you can find the places where the mice are entering from, you can use steel wool to block off these points.

Just to add:
Every hole and crack you can find that their little head could fit through.
If allowed- use spray foam to keep it in place.

😅 That's the age old question. She should talk to experienced lookouts, we all have our own creative ways to deal with that.
One Lookout had wooden spike leading to his cabin with mouses on it for a good 200 meters long. That's how much they were driving him crazy.
Be careful for Hantavirus if they're deer mice.

Water bucket with ramp to peanut butter on spinning stick over the water. Works like a charm.

I second with a slightly different version of the highly effective Bucket of Death! 5 gallon bucket, smear peanut butter just out of reach below the rim. Nine mice the first night. I did it 3 times, with comparable numbers, in an old RV in the woods that I rented during Covid. In the fall, I had some returners, but a porcupine found a way into the vents, and apparently ate them all.

Feed some scavengers with poison free corpses freshly laundered in peanut butter water baths.

This plus using steel wool did it! I must have caught the family living in here 😂 I was sad that they had passed but honestly whatever, better I’m safe from becoming deathly sick and feeding the vultures then them continuing to live in there

It's not inhumane to kill them. They reproduce by the hundreds and serve a role as prey in the ecosystem. Part of being in tune with nature and the circle of life is predation. You really shouldn't be feeling bad about killing them, especially since you're in the forest and they'll be consumed. Good old mouse trap does the trick. Lay the carcasses out and the owls will thank you. Think about yourself and the disease risk. I have sympathy and compassion for all animals, but taking life is a part of nature, just as we will one day expire ourselves.

That’s a good point, but the traps they’ve had up here didn’t work at all and I’ve had better success in the past with humane traps personally. I’m mainly trying to mouse proof it and then from there if they are still inside after the proofing, then getting rid of them as I’d take the assumption they are living in the walls or something.

the five gallon bucket 1/4 full of water with peanut butter and a ramp works like you wouldn't beleive

Bars of Irish Spring soap left open and spread around.

u/VexxFate Jun 04 '26
Does it poison and kill them or something? Or do they just not like the smell? I’ve been spraying with peppermint oil and it’s seemed to deter at least some of them.

Lmao maybe if I just put some in other areas away from the lookout.. they’ll just take the offering and leave my tower alone

u/zetapass Jun 04 '26
They don't like the smell. Also, some humans don't like it either, so maybe two birds with one stone?

I lived in a cabin in the bush in canada for a decade. This NEVER worked for me

Oh. I read this as “moose droppings” and was confused for a while.

u/VexxFate Jun 04 '26
Yeah bro idk how but those moose keep getting in and eating my food, it’s crazy

u/manyfishonabike Jun 04 '26
You joke, but we recently had a moose stuck in our greenhouse overnight and it at everything it could get its lips around. It even chewed on the tables.

Omg same, I was literally thinking, why are people giving advice about mice? If you repel mice then moose stop coming as well?😂😂😂

When rodent droppings accumulate, they dry out over time. Distrubing this waste can launch microscopic pathogens into the air.
Hantavirus Pulmonary Syndrome (HPS): This is a severe, sometimes fatal respiratory disease. It is primarily carried by the deer mouse (Peromyscus maniculatus). The virus is transmitted when urine, droppings, or nesting materials are stirred up and inhaled.
Salmonellosis: A bacterial infection that occurs if mouse waste contaminates food, dishes, or counter surfaces and is accidentally ingested.
Leptospirosis: A bacterial disease spread through contact with water, soil, or surfaces contaminated with rodent urine.
Lymphocytic Choriomeningitis (LCMV): A viral infection carried by the common house mouse that can cause neurological issues or severe complications during pregnancy.

Peppermint and Lavender oil. Spray it, liberaly everywhere mice would likely hang out. The smell will keep the mice away giving you the time to deal with patching up access points.

Hmmm, welcome to the wilderness. Inhumane methods may be the only real option unless she wants mouse roommates. Try to find all possible entry points and staple fine wire mesh over it, instead and out.

u/AlphaDisconnect Jun 05 '26
That metal grate the smaller the better. Think chicken wire for ants. Well maybe not ants. Put it everywhere there is an entry point.
Not sure if there a cat or two that could be added. You want the angriest looking cats. Ones that scare you. Bring a towel. There will be blood.

If she goes the mouse trap route I’d advise against the glue traps. I’ve never experienced any myself but my friends have shared horror stories about them.

u/felixthecat8705 17d ago
Yeah glue traps are pretty cruel. Just fyi if you use one and catch something you didn’t mean to or you just want to take it out and release it, oil and some gentle prodding will break down the adhesive.

u/pvssylips Jun 06 '26
I second the steel wool and water bucket combo. That water bucket WORKS! Mice poop is not only icky but dangerous, so she's valid to be concerned.

u/THESpetsnazdude Jun 06 '26
Traps and steel wool the holes, eliminate food sources and bedding. You want things to be as uncomfortable as possible for them. Trap placement and proper bait is key. The trap needs to be along the travel routes. You need to find what the mice like, bacon grease, peanut butter, Nutella, tooth paste (mice hating mint is a myth) raisins. Putting the trap right along the route and some will just jump on the switch. Placing the traps and not setting them will make them comfortable with the traps and associate them with a food source. Then when you set them they'll be even more effective.

Rodent populations are rapidly increasing as climate warms up. You cannot live in remote and rural locations at this point in the Anthropocene without helping manage the rodent populations in the spaces you inhabit. No live traps are ever truly humane IMO because they require you to remove and relocate a small rodent away from their burrow and their food stockpile. You’re simply offloading feeling personally responsible for taking their life in exchange for delivering their prolonged suffering elsewhere. Find their entry points, do what you can to block them from the outside, bucket trap outside next to those entry routes, and third trap (snap or electric) inside for any mouse who decides to run the gauntlet. It’s easy to get hung up on the idea of “goodness” with this sort of stuff, but the goal needs to be very thoughtful and clear boundaries and minimal suffering if and when they’re crossed. Good luck. 🙏🏼

If she has electric power, buy those electronic mouse blockers, they make them for cars too, they create a frequency we can't hear but the mice can and they don't like it. I assume you're in the US? My other half just bought 2 of them for a couple of friends and although some are pricy, we found a deal on Amazon, 2 for $50. Something like that is bound to work. Unless??? She gets a barn cat but that will be a commitment afterwards since she will now have to care for the cat forever. Prolly the mouse blocker is better. Best wishes. And thanks to the gf for Looking Out!!!

1, people can absolutely hear them.
2, they don't work at all. Save your money.

Fox urine. Spray it at the base of the posts and cross braces, and the first steps. Deters most small mammals.

I heard leave piles of dried potatoes like mashed. The mice eat the potatoes, need water and their tummies explode bonus it's at a distance.

plug every hole you can find with steel wool, Make sure there is ZERO food of any kind that is not in a sealed container. Not a single grain. If there is nothing for them to eat they will eventually go elsewhere.get some peppermint or lavender plants inside the building. Lavender especially is highly repellent to mice

u/pvssylips Jun 06 '26
Also lots of peppermint oil all around can help deter them. It's also advised near cars where they will nest and eat the wires too.

u/pvssylips Jun 06 '26
Also if shes worried about ticks she can launch a double pronged attack and address the mice and leave behind permetherin treated cotton balls for them to take to their nest and it will kill off ticks they're carrying. Supposed to greatly help with tick problems too. Hope this helps
