Maggots "tip line"

[Maggot]

I have found that when setting up a DE grid for a pool to always wet them down

Also when putting the cap back on to a metal container like polyurethane or acetone or paint reducer take a piece of wax paper and put it on the place that the cap goes on then put the cap on. It puts an airtight seal and makes it easy to unscrew the cap.
