Napthalene smells like **** and is a poor insecticide. It's used
in closed spaces where the concentration of the vapors builds up.

I'd spray some permethrin-based insecticide in the vicinity,
and maybe even inside the unit.

The stuff is available in the form of bug spray which contains only
around 0.25% of the stuff. It leaves no visible trace and the sprayed
areas stay effective for weeks to months.


I see DEET affects plastics and lemon eucalyptus oil as well as DEET has
only short term efficafacy. So something lasting years looks unlikely.
Perhaps advise the owner to squirt permethrin aerosol in the vent slots
in a marked safe placeevery couple of months .
