Your welcome.

One thing I didn't point out is that when the square container goes in the bucket it does not sit on the bottom, it sits part way down wedged by each corner. It is actually about 3-4" from the bottom of the square container to the bottom of the "bucket".

Just wanted to add that because if your container sits on the bottom then you tend to squash quite a few flies when you tap or shake the bucket, and that they would also be able to climb back up the square container instead of staying in the bottom of the bucket where you want them.
