I think the white would, with an app of chalk dust down, and on it around the border of the exterior walls. I use powder laundry soap for the interior. Has made the biggest difference in keeping all creepy crawlies out. Being that spiders prefer it dark. Less likely to attract them with white versus red.

Do any types of rock attract spiders and other insects more than the rest? We want to use either red lava rock chips or white marble rock chips. Would one be better than the others? And what do we use to kill and keep bugs away long term? Thanks!
