Step 1: The Wonder-weapon:
a plastic bottle. just pull it out of the trash, or, better yet, pick it up as litter.
Step 2: .... Snip Snip Snip ....
cut off the top-part (use scissors, knife, teeth..)
a n d
have a piece of wire handy (although you can also use a piece of smooth wood, see more below)
Step 3: Insert
the wire (etc) gently for some (under-cut*) hole in the bottle cap
* here done with a needle, or any other sharp-pointed object... undercut, because you want a ´natural seal´ to occur
Step 4: Support
not necessarily needed, but helpful to keep the gadget upright: use a second cap (or even a disk you can cut out of plastic, etc) pushed over the wire and down into the neck of the bottle - see photo below
Step 5: Hook It, Load It
form some simple hooks on the ends of the wire (obviously cut to any size you need).
turn the gadget upright, fill it partly with water (soit will create a barrier between the wire and the bottle-top the ants cannot cross)
hang it, wherever needed (f.e. a branch, or string, etc)
the hook below takes the ´load´ (a bag with food etc)
see note above: if you dont have wire use a piece of round smooth wood > not the ends so you can attach strings
Step 6: Done
.... sorry ants.... next time.... somewhere else....
ps, work less, play more
