I spent 10 years in Real Estate owning and running L J Hooker franchises and saw my fair share of termites.
Termites dont care what they have to travel on, to get to wood. They will climb anything and everything the moment they find wood that they want.
Alot of people offer up a sacrificial piece of hardwood like a railway sleeper away from the house/shed etc when termites are around so they go for that and not your property. It takes them a few years to eat the hardwood sleeper, but only months to eat your house.
My advice, spray termite barrier everywhere very fast ! both in and out of your shed, and around your house.
Rats chewing the wiring harness is also another big worry when a pinny is in a shed.
