Openings in the bottom section of the metal mesh shroud align with the seed tray, providing birds access to the food. When a squirrel climbs onto the feeder, its weight automatically forces the metal mesh shroud down, closing access to the seed. Squirrels and some large birds are foiled but not harmed in any way.

Weight Adjustable for Selective Feeding

 Squirrel Buster Plus Weight Adjustable

The patented adjustable spring mechanism controls how much weight the metal mesh shroud will support, allowing the birds to feed. Any additional weight will activate the closing mechanism. Use the feeder at the factory setting before making any adjustments.

Squirrel Buster Plus Detachable Component System 

Squirrel Buster Plus Ventilation System

Detachable Component System

Squirrel Buster Plus components are designed to be assembled and dismantled easily by hand, without tools, and to fit into your dishwasher.

Dishwasher Safe Bird Feeder

Clean feeders are as important to wild birds as clean dishes are to humans. Grimy bird feeders can be a source of illness that can be fatal for birds. With squirrel Buster Plus™ detachable components it is effortless to provide the birds you love with a safe and healthy feeder. Regular cleaning of your bird feeder is essential and should never be delayed. Spread the word about clean, safe feeders.

Seed Tube Ventilation System

Damp and decaying seed decreases bird traffic and can spread disease. Most transparent bird feeder seed tubes trap solar energy just like a greenhouse. The air in squirrel Buster Plus rises and escapes through patented water-proof vents at the top of the feeder. The escaping, heated air is replaced by fresh air entering through the seed ports at the bottom of the tube. The birdseed remains fresh, attracting more birds.

Squirrel Buster Plus Adjustable Perch

Perching Options Using Adjustable Posi-Grip Perch

Thick, adjustable-length perches with textured surfaces provide a secure and comfortable grip for birds. Attract small birds such as Chickadees and Finches (while deterring larger birds like Grackles and starlings) by shortening the perches. Perches can also be extended just enough to attract medium-sized birds including Grosbeaks and Woodpeckers. Grackles, starlings, and Doves can be deterred by using variable length perches and the adjustable spring mechanism.

Squirrel Buster Plus Cardinal Ring Perching System

Cardinal Ring System

The Squirrel Buster Plus can be used with or without the Cardinal Ring System, an optional posi-grip ring designed especially for Cardinals. Cardinals prefer to grip a thick-textured perch and, because it’s awkward for them to turn their short necks to feed, they prefer to face their food source directly. The Squirrel Buster Plus Cardinal Ring System allows Cardinals to eat facing the seed from a secure and comfortable perch. These Cardinal-friendly feeding features combined with a bush-level location make Squirrel Buster Plus very inviting to our scarlet friends.

Squirrel Buster Plus Need for Clearance Diagram

The need for clearance

Remember it’s a squirrel’s weight that triggers the closing mechanism. If a squirrel can reach over from a nearby foothold and avoid placing his weight on the feeder, he can access the birdseed. To overcome this problem, allow for at least 18 in./47 cm of clearance around the feeder. This will force the squirrel to climb onto the feeder and trigger the closing mechanism
