DayLodge DIY Kit arrives with pre-cut and pre-roughened wood parts, screws, adhesive, plastic lumber roof, and mounting screws (however, the same bat house is available assembled) for those looking to speed up their bat house project. Holds ~100 bats safely. Approved by Merlin Tuttles Bat Conservation. The DayLodge features a very strong, and very simple roof construction that creates a super solid bat house that will last many, many years. It is capped by a solid piece of 1/2 thick recycled plastic lumber, and will last decades. It is suitable for kids ~8 and up with supervision, workshops, school projects, scout projects, or anyone wishing to build their own solid, modern bat house without fabricating parts. This is the easiest to assemble 3 chamber bat house BCM has offered. DayLodge comes with exterior structural mounting screws that support the entire bat house, eliminating the problem of roofs and backs separating. DayLodge is the strongest, most long lasting plywood bat house BCM has ever produced.
