Re: Removing Can Labels for roaches or bugs?
I'm currently commuter cruising the Sea of Cortez...so have been anchored as well as in marina's. I have canned, boxed and fresh food onboard from mini tiendas, small grocery stores and mega stores.
Never had roaches or ants aboard. (I've had many flies & moths this summer.)
I've never removed labels from cans.
I do remove some cardboard packaging but that's saving space & keeping trash off the boat while I'm cruising. Trash can build-up.
I suspect this is an old wife's tale. (My wife hates when I say stuff like that!)
