Bird Repellent: How to Keep Unwanted Birds Away with a System-Based Approach

Unwanted birds can cause significant damage to agricultural crops, interrupt industrial operations, and even pose a danger to humans, such as bird strikes on airports. And when birds are rewarded with food or safe roosting, they can be difficult to keep away. Luckily, by using non-lethal bird repellent tools, you can chase and keep birds away.

Bird repellent systems fall into three classes: audio deterrents, visual deterrents, and active deterrents. By using a wide variety of deterrents in each class, you create a bird prevention system, thereby efficiently and affordably protecting your control areas; from a backyard blueberry crop to the biggest airports in the world. While individual species can be more sensitive to specific stimulus, the general strategy holds true for all species of birds.

These deterrents work by sending biological messages tricking birds to believe that they are in constant danger when they remain in the area. For this to work, the fear you impart must be stronger than the attractant that brought them there in the first place. By combining different types of deterrents, you create a “landscape of fear” that will overpower the strongest attractants.

The Three Most Common Bird Repellent Tools (and How to Use Them)

Audio Deterrents: Loud and frightening noises startle birds from the control area. Our propane cannons emit a 120 Db. blast, like the sound of a shotgun. All species of birds are sensitive to this sound. By continuing to move the propane scare cannons from place to place, you will keep birds from becoming accustomed to it.

Propane Cannons can be effectively combined with the Bird Gard distress caller. By replicating the sounds of birds injured and in distressed, unwanted birds connect the area with direct danger. Specific combinations are available to most North America problem bird species.

Visual Deterrents: Birds strongest sense is their eyes. Decoys and predator effigies trick prey species into believing predators are hunting in the area, further convincing them that your control area is unsafe to linger in.

Some social and intelligent birds species will also avoid areas if they believe other members of their species have been killed in the area. Our dead Crow, Gull, and Pigeon decoys are a non-lethal way to replicate this effect. The real birds will often first fly in briefly to inspect these decoys before leaving the area permanently – this is a very good time to hammer them with a pyrotechnic barrage, further enforcing the idea that your control area is not safe.

The best bird control programs combine audio, visual, and active deterrents.

Active Deterrents: As its name suggests, active deterrents are direct human controlled responses to birds. Since you are using the deterrent manually, and only when you need to, it is difficult for birds to become accustomed to these disruptive sights and sounds.

Our most efficient and popular products are 15mm pyrotechnic scare cartridges. These cartridges travel between 90’ – 1250’ through the air with a variety of visual and audio effects. We stock the largest selection of pyrotechnic scare cartridges in North America. Combining different cartridges creates more chaos and prevents birds from getting used to any one special effect.

We also supply the Fly-Away laser, the strongest hand-held bird control laser allowed in Canada. Geese are particularly sensitive to the strange light pattern from the laser and react immediately.

Systems-Based Approach: Like all tools, different bird repellent tools have their strengths and weaknesses. The most effective strategy is combining multiple deterrents, creating a landscape that birds find confusing and terrifying. Don’t leave any safe havens in your control area; active and immediate use of deterrents prevent birds from being rewarded. The best bird control programs combine audio, visual, and active deterrents.
