Help the bluebirds in your nest boxes build parasite-free nests with the Songbird Essentials Bluebird Nest Lift & Blowfly Screen. Blowflies often lay their eggs in nests inside bird homes, and the larvae feed on the nestlings to gain strength. This durable, mesh screen rests in the bottom of your existing nest box, creating an elevated platform to accommodate nesting material. This keeps the eggs and nestlings off of the base of the home, so they remain dry and safe from blowfly larvae and other parasites. Not only does this item keep the birds safe, it also creates a gap between the floor and the nest for you to easily remove any parasites you may see. The plastic coated, metal construction will remain durable for seasons of service, and the convenient size fits inside many bluebird, woodpecker, or other bird houses. Keep young bluebirds safe from parasites with this Bluebird Nest Lift & Blowfly Screen.
