I read of releasing them into the wild?
They are alien species and destructive. Do not release them.
Our coach is tight but we use home defense at openings in water bay the only possible site for them to come in now, except the dash air intake.
I have been trying to find someone to devise a filter housing etc to take care of that, primarily to stop dust and bugs while on the road.
I see bug traps mentioned on the net for stink bugs. Might take several, but I don't know.
They made it this far a long time ago, but they just disappeared after a season or two. I don't know why. Only occassionally do we see a domestic counterprat.
