I put one on my cargo van after rodents chewed through a plastic vacuum line. Keep in mind that it is a parasitic drain on the vehicle's battery.

Before the electronic device, I deployed mothballs under the hood. Kept in a canning jar while driving.

Difficult to know if the device works, at around the same time, a pregnant feral cat appeared at the RV park.

Sadly, the little lizard population has disappeared. Maybe they moved outside the fence.
 
You can repel them but they will likely keep coming back if you are in one place.

My Great Great Grandad & Grandad had a dairy farm at one time and found a simple & safe way to dispose of rats and mice. They mixed concrete mortar with corn meal and placed it in one bowl. Next to it they placed a bowl of water. Rodents would eat the cornmeal mortar mix and then drink water. The stuff would harden up in them and that was the end of them.

The farm dogs and barn cats wouldn't touch the stuff so they were in no danger. Only the rats died of terminal constipation.
 
The guys working at the place where I got my rat chewed wire repaired sell them . I asked the mechanics opinion and they said maybe they work some of the time but do not think it works most of the time.

They repaired the wire and wrapped it with rodent deterrent tape. That did not work either. Had another rodent chew into it.

The parts counter guy explained that rodents in the desert areas nest in and eat strong smelling plants. So hot pepper tasting stuff does not deter them. Strong smelling oil and sprays do not deter them either. Mice and rats are not actually afraid of lights. But movement makes them run and hide.

I encased the wire the rats kept attacking in wire mesh that is used for screening on basement and soffit venting to keep rodents out. I also moved my camp to a different location that had no evidence of rodent burrows. The latter is the best way to reduce rodent attacks. Stay out of their prime territory.
 
They are attracted to the smell of food and to water including your garbage and waste water. So put your shower tent well away from your vehicle. Do not set bags of garbage close to your vehicle. Dish washing water needs to be emptied well away from your camp. If you are going to cook food on a campfire realize they will be attracted to that fire ring. It is not just rodents that will come around for water so will flies, wasps, spiders, snakes, scorpions and birds. Do not put out bird feeders, rodents eat seeds. No deterrent device will overcome the temptation of food and water, especially in the desert Southwest. They will want to nest next to such sources.

Think of it like the precautions needed in bear country. These little creatures have hunger too.

Nifty for a dairy farm but not a great solution if you're in a vehicle.

They don't die right away so they will crawl back into whatever hidden nesting place they have in your rig.

When they do die they will start to stink and it could be in a very tough to reach spot such as behind paneling, under floors,etc.
 
I would suggest cats, but sometimes my masters bring home the critters to let lose in the house. Playmates.

That explains so much!

I'm sure no device maker claims 100% effectiveness but it's a sure thing that doing nothing will be 100% ineffective.

Please rethink how your great grand & grand dads related to rodents. What they did was unduly horrible! An old-fashioned rat trap is "kinder".

I know this was directed at another member, but me personally, I will not be rethinking how I relate to rodents. I dont relate to them at all so there is nothing to 'rethink'.

You do understand (I assume) that rodents carry diseases that can cause humans and pets to become sick, or even die. Not to mention contaminate your food supplies and render your vehicles inoperative, and that might happen when you need your vehicle to get out of harms way or maybe to a hospital due to sickness or injury.

Being 'kind' to them is not part of the equation. I am not advocating cruelty, but their ability to live un-deterred in my environments and possessions will not be allowed if I can help it. Whether I need to use rodenticide, traps, or repellant, they are not welcome visitors in my home.

There are humane ways to kill a rat/mouse. A big, old-fashion 'snap' trap is such a thing. The post that caused me to respond was a person offering a recipe (edible) that causes unbelievable suffering as the rodent dies. Why would anyone want to do this? I cannot enjoy comfort at the expense of being cruel to another.--- https://kb.rspca.org.au/knowledge-base/what-is-the-most-humane-way-to-kill-pest-rats-and-mice/
