It,s quite a big problem in this your not alone. If not removed will cause serious damage to hoses cables etc. Vehicles made abroad and stored for a long time before shipping can unknowingly have them. In the UK any time from now until winter December roughly they will look to move indoors if they can. A car parked in a garage nice warm engine etc. What you need to do is put whatever traps you prefer on the floor, those mat things are quite good. You could bait a trap with what you think is best . Be vigilant especially if putting car in a garage in a rural area, lift the bonnet regulary to check. They will nibble bite into cable, hoses sometimes unseen. Repairs can run into a lot of money. Good luck.
