Just about perfect
Cedarcide products are amazing. We spray outside and inside. Definitely keeps the spiders and silverfish away. I wish we could get the YardSafe without the sprayer, as we have about ten of them and no idea how to deal with all that extra plastic. I'm aware of the concentrate refill and we may have to go that route, but it would be far preferable to simply buy the YardSafe without the sprayer.
