but only twice a month until you get used to the smell. @mommytinkerbella2017

under the sinks, under beds behind and under couches and I've also come up with something get a spray bottle put some mothballs in but not too many. and then put in some mint oil, like the oil you get from the candle section at walmart, shake it all together and spray in corners of the room or in places where spiders would be after you clean, the smell is going to take some getting used to but ita worth it, spray a good two times a month. some people like up to 3 times a month or more @mommytinkerbella2017

so where do u put them. my mom used to use them I never asked what for tho @babypandaflexin956

@mommytinkerbella2017, They keep moths away, which I am terrified of and I've also seen mice and spiders don't like them either.

what do they do?
