just read about this for weeds.
probably work on pests also.
i refigured from a gallon to a quart.
1 qt. of 5% white vinegar
1/4 Cup of salt
1/2 Tbl of dish soap
article said higher acid percentage vinegar will kill it all weeds, grass, flowers etc. .
so will be using the this fall to reclaim some ‘garden area’
don’t water near dusk or night.
snails use the moisture to glide on.
another good deterent is broken dried egg shells which slice the ickies up.
good luck.
