I have a thin aluminum engraved plate [9quot; X 110quot;] that I want to attach to a stone as a marker.
They are the larval form of the moths you are seeingYou will need to wash all the clothing, walls and containers in the areaThey lay eggs on nearly anythingThese can get into food and food containers, too, so you may need to wash cupboards, too.
is it really 110 wide ? Oh well I hope the stone surface is somewhat evenbut you can use a liquid nails or even a silcone adhesive, both of which somes in tubes for a caulk gunyou can apply it quite a heavy zig zag bead on the back of the plate but dont get any closer than 1 to any edgethat way it will not squeeze out when you push it against the stoneyou can keep it in place with a duct tape until it sets.
