Last summer we also had an issue. I don't mind but the kids and washing machine operator
are really scared.
The "nest" was inside the area where the roof meets the wall, impossible to access.
We extended the piping of an old vacuum cleaner, and positioned it close to the inlet to the nest. Had it running daytime during a weekend, blocked "emergency " exits before that
They all got sucked in, hundreds of them in the bag when operation was completed.
fun on a boat is inversely proportional to size...sort of anyway
