ok for this i wanted a safe way to stop ants from getting in my Hummingbird, and Suet feeders, yes water works but its hot and dry in the south and it dries out, so i tried essential oils as a barrier, seems to work well
You will need old water or soda bottles
scissors do not run with them!
wire or coat hangers the metal kind.
cotton or some absorbent material to hold oils
some essential oils, peppermint, lemongrass, cedar, etc
Step 1: Cut Bottom Off
cut bottom of bottle off save it for later, poke a hole in lid, and in bottom center.pass wire thru
Step 2: Add Cotton Balls
on wire near top add a small wire to hold cotton balls in place. add cotton balls
Step 3: Add Oil to Cotton Balls
ok put a few drops of each oil you use on cotton, then push bottom on wire to make a hold and slow evaporation of oils. note you could use a poison but i don't like the thought of that.
