Thank you for all your replies, made some pretty depressing reading.
We have heard about the water bowl and light but that won't be an option for us while the RV is locked up unattended for 12 months. Guess we have to look for some eggs and kill those before they hatch. If we can get as many as possible before we leave as Louisiana is not known for them.
We find it amazing that in our 10 years of rving around all 50 states this is the first time we have ever come across these little buggers. We have camped in the north West in Fall before but no Stink bugs then.
At least the ones we have killed in the last week didn't seem to stink when we squashed them !
Thanks again keep the ideas coming
