Thank you for that information. I'll go with the Moth Balls in the open zip lock bag. I'll throw a bunch of them in the engine compartment. Their current wood chip " home" is roughly 45' from where the car will be stored. One shed is smack in the middle of the wood chips, and they left. Haven't seen one in that shed for years. Nothing inside but push mowers and a few storage bins. They used to get up inside the push mowers,,,but no more. I'll throw moth balls in the shed as a precaution also. Thanks so much
