and nutrients and get everywhere. But they're easy to clean up. Other than those critters, if you keep the screens on both the unit and the fan, you shouldn't have any other problems. 6 years fulltime use for us and we've only had the "sawdust bugs" once. I wouldn't let it worry you too much.
Thanks Simply Sailing, it nice to know someone else has seen this one, well not nice for you but you know what I mean.
I have taken the Natures Head completely apart and I mean completely, they of course were every where and I mean everywhere
We left it outside so as not to offer up anything they can get into.
I wiped down the entire head three or four times yesterday (paper towels and vinegar) and they were back this morning albeit in smaller numbers. They are trying to migrate outside of the head but I think I am winning that battle at least I hope I am. Not sure where the new hatches are coming from so I will keep at it.
We will not be using any bug bombs, too toxic for us.
Hopefully as it warms up that will not give them more a favorable environment
in which to procreate.
Will post when all is back to normal.
Thanks for all the replies!
