QuadBlaster QB-4 Ultrasonic Bird and Bat Repeller

Blast away unwanted birds and bats -- the safe way! The Quadblaster Ultrasonic Bird and Bat Repeller features high-intensity sounds that are undetectable by humans, yet humanely disturbing to flying pests.  Place this electronic pest repellent outside, and let the four ceramic Piezo speakers get rid of birds and bats in a 360 degree radius, with overlapping patterns of uncomfortable ultrasonic waves. The QuadBlaster Ultrasonic Bird Control device has a compact size of 12" x 12" x 4".

This do it yourself pest control is amazingly simple to set up and even more simple to operate.  Simply find a place outside to set down the pest repeller, and let this electronic pest control device do the rest of the work.  The QB-4 can be set to a 20 kilohertz mode, a modulation mode that produces an uncomfortable “warble” for birds, or a combination mode that fluctuates between constant and modulation, creating the most uncomfortable environment for feathered and flying pests, without creating a single noise in human ears. Easily sequenced, the speakers can be programmed to emit speeds ranging from 10 to 110 rpm.

This advanced bird guard was built with its user in mind. The design is optimized for simplicity. The pieces are structurally sound, and the style is unobtrusive, blending in easily with any home or business decor. This bird repellent is not only safe, humane, and attractive, but will effectively rid your property of health risks, unsightly bird droppings, and unwanted birds. It’s no wonder the QB-4 is one of the most effective bird repellents on the market! Aids in repelling pigeons, crows, sparrows, starling, seagulls, grackles, cormorants, vultures, rodents, other pests, and many more. 

The QB-4 plugs into any convenient 110v AC outlet and uses less current than a 10 watt bulb, costing only pennies a day to operate.

The optional extension speaker (Sold Separately) can divert the ultrasonic sound from the QuadBlaster's one or two of the built-in speakers to the remote, extension speaker. This provides many expanded possibilities to repelling those pesky birds! Also available, a set of four (4) extension speakers. Each extension speaker includes 100 ft. of wire.

Harmless to birds & bats - ecologically safe bird & bat repeller!

The irritating sound waves produced by the QB-4 ultrasonic bird & bat repeller will not harm birds or bats, but will attack them aggressively in any enclosed or semi-enclosed areas where they roost. The adjustable variations in pitch and sequencing make it difficult for the birds & bats to acclimate to any constant sound pattern.

Install QB-4 wherever birds & bats infest.

QB-4 bird & bat repeller is designed to act as an important aid in routing birds or bats from their infestations in plants, warehouses and semi-enclosed locations such as loading docks, railroad sidings, tunnels, breezeways, underpasses and storage sheds.

Installation couldn't be easier.
There's no "top" or "bottom" to the unit, so it can be mounted in any direction - on any plane - with screws, nails, wires or adhesives.
