Mason Bee Nests - BULK Replacement Tubes

Orchard Mason Bee Nesting House - Case of 600 Replacement Tubes

Case of 600. ÊToxin-free, Kraft paper tubes are 6 inch long with a 5/16 inch diameter opening (use 3/8 drill bit for dedicated holes). Each is wrapped in acetate for added strength and moisture protection. By providing smooth paper tubes, the females have a lot less prep work to do for nest construction and can channel the extra time and energy into egg laying.

Tubes are superior to holes drilled in scrap wood because they are easily removed and replaced, preventing excessive accumulation and infestation by pests. Used nest holes may harbor mites that feed on mason bee babies and juveniles. These parasitic mites can buildup from year to year, harming the new brood.

By having shelters with removal tubes, it is easy to replenish the nest with a fresh supply of clean tubes, providing the pregnant females with a safe place to overwinter their offspring. Tubes that were never utilized may remain in the shelter. Compressed air can help clean out any debris or other insects that may have accumulated in the unused tubes. Case of 600

ALERT: We also have Master Cartons of 5000 Tubes bulk packedÊfor only $535 plus a flat shipping of $38. ÊThat is a sizable discount off the retail. Contact us to special order this item.
