Good Morning,

This is a bit of a home remedy but you could spray the moss with a mixture of vinegar and dish detergent. It will turn the moss brown so you'll need to sweep it off the pavers after that to clean it up. The solution can be made up of a gallon of vinegar mixed with a quarter cup of dish detergent (this is a binding agent). I'd be careful that it does not get on any other plant. All it does is burn the leaves of plants after a day or so. It does nothing to plant roots so by sweeping the dried, brown moss off, you may be able to remove the spores and roots that could grow back when the conditions are right (wet, cool, shade). I'd also be careful not to hit any beneficial pollinators that happen into the area while you're spraying because this is an acid that can burn most organisms.
I hope this information helps.

Thanks for using our service.

V/r,

Doreen
