Prevent blowflies and other parasites from overtaking several bluebird nests using these Classic Bluebird House Nest Lifts by Prime Retreat. Blowflies commonly lay eggs inside of bird houses, and the larvae feed on nestlings, weakening them. A fantastic way to deter this is by elevating the nests off of the base of homes, easily accomplished with these 4 stainless steel frames. Slide 1 lift into each of your existing avian shelters, offering birds a platform for building their nest. This not only keeps the nestlings off of the bottom of each box; it also allows excess water and debris to fall away from your feathered friends. The pieces also make it easy to remove any parasites or other debris from below each nest during routine maintenance. Their 0.375" square mesh is sturdy enough to hold a nest, while small enough to let debris drop through it unhindered. Crafted of stainless steel, each platform provides durability and seasons of service, and the items are sized to fit in most bluebird style bird houses easily. Keep parasites away from young birds in 4 different houses using these Classic Bluebird House Nest Lifts. Made in the USA.
