If your long lining colony traps you would have to have a trailer to haul around funnel type traps. But they do have their place.
That is a downside if you have to haul them around.
Normally they are left on site on an RTL at the spots that produce every year.When I used some back in the day,I would hang them under a spruce,and give them a shot of black rustoleum when done with them in spring.Dont leave them on the ground.
Like minnow traps left out on the land,they will rust if not maintained.
