I wish our issue was mice rather than rats. The joys of living in the countryside. The rats are nesting on top of the engine cover and storing food there plus using it as a toilet. No issue with our 1996 Corolla as no place in the engine bay for them to nest. We managed to kill one rat who was a bit slow leaving the engine as fan nearly sliced it in half. Also our cats regularly catch and kill rats in the area.
I sprayed the top engine cover with the Dettol spray which seems to have helped. I also turned the vehicle around and reversed into my parking spot. Regarding rats I am not very humane as they can cause severe sickness in humans and even death!
We tried killing the rats we had at the back door of the house during lockdown (local takeaways shut), using Rentokill traps. But we got a bird or two as well as two lots of 6-8 rats, so we abandoned the traps. We had to buy a bait box from the local hardware shop & put it in the rat run; that sorted the problem.
if youre going to move your motorhome, why not drive onto plastic rubble sacks (toolstation). The weight of the motorhome will make the bags wrap up slightly so peg or weight the sacks down after you have driven onto them and then add the jeyes fluid onto the rubble sacks, that way it doesnt sink into the earth and will potentially create a small reservoir of the fluid around the tyres?
We used the Jeyes Fluid under the motorhome, wheel arches and tyres. We also sprayed inside the engine with Lemon Dettol. So far these are the only things that has deterred the mice Fingers crossed.
not a problem, glad to see that its worked for you aswell, it cost us a fortune when we had a problem trying to get rid of the nasty things, all we do now is go over the pitch about every 6 months with a couple of watering cans full of it as a deterrent.
