But behind lovely landscapes are actions that will threaten your health and the environment. Be certain to take care of a clean and tidy yard and garden space. Remove any excess materials and/or mulches that are not in use, as this will discourage mice and the like from moving into the backyard. A dry crawl area is less vulnerable to attracting and harboring pests. Plus, dry wood is much less prone to infestations from termites, beetles, ants, mould and different widespread crawl area issues. Most crawl areas will benefit from a vapor barrier, however especially people who have a bare-soil floor.
