Hi Dolores, so how much of each of the three ingredients do you put in the lid? Maybe a tablespoon of each?
They are nesting under my deck outside my second story bedroom. Tonight I poured boiling water out there but do not think anything happened. I don't think they mimic the lobster?
This really does work. also squirrels hate moth balls I use them in the flower garden. for veggie garden place in cup so can't contaminate veggies.
