The best rodent poison that you can buy is Contrac. You can find it online. I get the small packets and spread them out in our crawl space and the garage. You can also get the big blocks and put them in the black plastic external cases that you see around strip malls (like a shoebox). Why I like the packets is you can see when the mice/rats tear into them. Then just replace the packets (after you clean up the torn one). Its a great way to see if you have a varmint issue. And the other good part is I never see the bodies. They may be dead in the walls or wherever they were nesting, but I never see carcasses.
Rodent poison will kill them but they are already in the vehicle.
I use Moth Balls. Put one in the cabin and one in the engine compartment.
I farmed for 35 years and it did keep the mice out.
I did have a squirrel chew up some wires on my plow truck diesel.
Transmission wires and insulation. It was after the salt.
Keep the salt off too!

Last week my son started our Bronco - and a raccoon scampered out of the engine bay!

Looks like the raccoon was sleeping on top of the engine. Grimed it up with muddy paw prints and oily residue. Tore some foam insulation in various areas. Also must have got caught in the running serpentine belt, pulled out clumps of hair when escaping.

To add injury, while cleaning the engine yesterday, I notice mice had also invaded. On the top firewall side of the 2.3L engine, there is a plastic cover over foam insulation, with a small opening. A perfect "mouse house". Mice crawled inside and tore up the foam insulation making a nest. :(

Does anyone know offhand what is that insulated component (shown below with red arrow)? Assuming Ford put all that foam insulation there for a reason, I wonder what is the risk operating the Bronco for a while with some of it missing?

I live in rural area with critters also. My huntress cat takes care of all of them. Also Tomcat makes a spray that works well. Ace has it.

You would love Loki, (see avatar) he killed a few raccoons that were trying to den under my house, including a full size daddy raccoon in seconds. I was freaked out when I saw him go after it, after all, it was a wild animal with claws and teeth, but Loki flipped him right over on his back and crushed his belly & inner's with his jaws (no blood) in 2 seconds flat; it was amazing to see.

Loki would never hurt another dog (or a human) regardless of size, even a noisy ankle biter and he even tried to play with a coyote, but ANY OTHER animal that he can chase down and kill he'll go after. I never had anything get into my truck after I got him.
Yep, Siberians are fantastic hunters. Birds, opossums, rats, rabbits, skunks. Not so good at rattlesnakes. Unfortunately, I lost 3 dogs from secondary poisoning :mad: 😢 because if it was in the yard they would kill it & eat some of it. Again, not so much for rattlesnakes, thankfully we got the boy through that before losing him to a cancer 2 years later 😢

Please don't use poison, I've lost 3 dogs from secondary poisoning see above post. Not sure what the autoloaders is but a dunk the rat trap works pretty good. Feral cats are great if you have some property.

I started using peppermint spray. I was using coyote urine but the smell is horrible and our dog was getting too interested. (Her litter mates have coyote kills.)I can't use poisons because our of pets.

Of more serious concern is what will happen when our Drahthaar gets a whiff of some critter in there! Rodent damage can't compare to what a Drahthole determined to dispatch fur can do to a vehicle. She's chewed through PT 2x6 shed ramps simply because a mouse or 2 had a regular path under it. (Funny, she points the grill and bumper if there are pieces of birds in there.)

Decided to check to see if I had mice several weeks ago, and I noticed some mouse droppings and slight chewing on 2 wires. I got some mothballs from the hardware store (50 mile drive) and when I popped the hood to place them a mouse was looking at me from the air filter box! Got my tools out and popped the cover and no damage (the mouse was also gone), and since placing the 4 perforated bags of moth balls, no more mice!

If you go for rodent poison, skip the Big Box and hardware store stuff. You want to go to a farm supply outfit for serious products.
Regarding racoons and opossums, look into repellants that utilize coyote urine. Don't ask me how they get the raw (pun intended) ingredient. I don't know, and don't want to.
Coyote wranglers, I assume!

I give a second here! I have had over $4k total in damage to wiring, insulation, and fuel components in a 5 year period between my F150 and Camaro. Mostly squirrels, but some mice too. For the last two years I have been putting Uncle Gus rodent packs under the hood on each fender well and on top of the fuel tank near fuel pump. I have the in Tupperware containers with holes drilled in them. Then spray them down with peppermint spray as well as the hood liner, fire wall and battery insulation. I got a gallon jug of peppermint spray off Amazon. I do this on the first of each month. Haven’t had a problem since.

When it’s outside in the summer, I keep a bit of water in it. Only an issue then is the occasional squirrel. The raccoons are gotten by large “doesn't have a heart” trap.
I have a similar trap and don’t use it dry. In the winter months, I use windshield washer fluid or RV antifreeze. Keeps the liquid from freezing. Thing works great. But it is a little nasty to empty if you don’t do it on a regular basis.

This was the cabin air filter inside my old Escape. The filter was gone and replaced with a mouse nest. Squirrels and mice squatted in that engine compartment but never ate any parts other than the cabin air filter. But, that began my quest to eliminate the little varmits from this planet!

My wife had mice chew up some stuff on her engine. The odd thing is that I had a Mustang in the same garage for months at a time and my Bronco can sit there for a few days and no issues (so far). I wonder if she got them from her job.

I also got mice traps for garage, but haven't seen anything in them either.


And I live in a urban area too (though we have a good collection of rabbits and chipmunks in the neighborhood)

I heard about the moth ball trick, but I needed to kill mice/rats. And they have to leave the engine compartment at some point to feed, and they will find the Contrac.

But to the guy who posted after me, don't use Contrac if you have pets. I have a cat (house only) and no dogs so I was not concerned about them getting into the Contrac in the garage and crawl space.

Mix Jiffy Corn muffin mix with pure baking soda the Corn muffin mix will attract them and they cant digest the baking powder.. any rodents that eat this will die. As far as the racoon get a live trap and some cat food (wet) when you open the can don't tear it all the way off just crack it to expose food and zip tie it Hanging inside the trap. I have a friend that works at a local for dealer, he said he sees this a few times a month. I was told that the wiring is vegetable oil bases and that attracts the critters.

I'll give a third on this! It works wonders and the aroma isn't too bad. Also keeps spiders out too. We have some vehicles that sit for a while (old convertibles, truck) and hitting the engine compartment and the interior with some peppermint oil keeps all those away. For the interior i put a few drops on a folded paper towel. Works great.

Had a temporary solution earlier this year (see photo). Unfortunately, he moved on so I'm hoping that pickins were slim. My rodent problem has been dramatically reduced with taking down a large oak tree (and all of its associated acorns) 2 years ago.

We live in a rural mountain area with mice/pack rats a constant problem and raccoons/squirrels an infrequent one. While we use a 12v rodent repellant alarm under the hood we have found the best practice is to leave the hood up at night, preferably where there is a light shining in, as it seems mice/rats seek out hidden, dark spaces and we have never had an issue since doing this. Thinking the repellant alarm would work we left the hood down for 4 days only to fine the beginnings of a nest being created just below the alarm... Hood Up!

I use water in it outside only because the squirrels and gophers can jump back out if they don't drown first and I don't want to dump antifreeze out every time. In the winter I only have to deal with the mice in the garage. Leaving it dry works fine. Mice only seem to live a day or so in it. I had a skunk in one of my hav-a-hart traps. It lived for several days before it keeled over. My neighbor has a cat that roams around but it's not nearly as good as a family of foxes. They kill to live, the cat kills just to have fun.
