Have tried that - they seem to come back for more and it blows around the engine. I have two rat traps - the wood and spring kind but they seem to avoid them - these spanish rats are very clever ......my dogs chase them up olive trees and usually I have to climb up and rescue the dog !!!

I'd try a couple of bait boxes - something like these

The main secret to getting them under control from my mates experience (they used to get in his loft at his house) was to put the bait down, and leave it alone - they won't usually go anywhere near stuff that you've disturbed recently. He tired the traps, tried shooting them with an air rifle, neither approach worked. The buggers even managed to strip all the insulation off about 6 ft of the lighting ring main buried in the ceiling without suffering any ill effects, but the poison did actually work. If the area under the car is clear, I'd stick a bait box where you usually park it on the ground - if its really dusty there, then get the blocks that push onto the retaining rods (the ones in that listing for example are the type I mean) as you can always tip the dust out of it latter when you come to refill it.

RATS AGAIN Ok - I know it is not a Range Rover but my poor old Peugeot 309 1.6 is parked next to them and despite traps and checks found last night that the little buggers have moved into the Air cleaner - made a lovely home out of the filter paper and bred four little bastards (no wedding rings). They have also chewed holes in the plastic air cleaner housing and tube to the carb. So, can anyone suggest a good Peugeot Breaker who might have a 1991 - 309 1.6 petrol air filter case and associated plastic cap to carb ?

Shouldn't be too difficult to get hold of a replacement air filter housing but you should be able to get rid of the rats easily enough too. Just start the engine and revs the nuts off it, that should suck them into the intake........

RATS - Going to stuff their favourite corner of the P38 where the loom is their dining room with those stainless steel kitchen scouring pads - I know they can bite through anything but I reckon it will keep them away from that vital area - might confuse them ...............
