Choosing the correct spike solution

Bird deterrent spikes like Bird Barrier’s  Bird-Flite and Dura-Spike are highly effective ledge deterrents. They have been installed on thousands of buildings with  great success.  Selecting a spike solution requires careful understanding of the bird problem, bird pressure and species observed. Experience has shown that different bird control solutions work for different situations.

Never use a spike solution when the pressure is heavy, like an overnight roosting spot.  Typically these sites are ledges with an overhead cover of some sort (eave, roofline, etc.) The birds here will “fight” for their overnight spot and often move the spike with their bodies and or place nesting materials directly on top of the spike.






Spike is also not the most effective solution for birds larger than pigeons. As seen in the picture, larger birds can easily bend spike almost flat, even in daytime perch situations.






Bird Flite bird spikes are effective against pigeons and gulls. It is effective on ledges, parapets, window seals, signs, chimneys, roof peaks, lights etc. Bird-Flite is installed on thousands of U.S. buildings with an incredible success rate. Its stainless steel rods and U.V.-resistant polycarbonate base are very durable.

Project: Dura-Spike

Case #1

A new university parking garage became the home for winged visitors. The parking garage sought the services of a local company to relieve the pigeon problem the new garage was experiencing. Students would leave their cars for morning classes to return to a complete mess. A new building, such as this, with no prior visitors is often a target roosting place for pigeons.

The model solution was Dura-spike, an all stainless steel spike that comes in three-foot lengths and is easily installed with Bird Barrier bond or screwed down. Dura-spike is ultimately a discreet application that physically stops the bird from landing, causing it to travel elsewhere. It is warranted for ten years and is completely humane as the tips of the spike are blunt.

Case #2

The construction of a new football stadium took two years and within that time, pigeons found the area to be a comfortable place to call home because it provided shelter.

The maintenance crew found they were repeatedly power-washing the problem areas every other day. The pipes were the main crisis as they were completely exposed on all 11 floors of the stadium. Although, bird deterrent had been previously installed by another company, it did not prove to be long-term.

Dura-spike, was applied to the most affected areas first, but installation proved to be a challenge.The pipes were nearly 40 feet high and a scaffolding ladder was used to access the areas. The most difficult issue was securing the ladder on the steps of the stairs.

Workers were very pleased with the spikes.


Case #3

An administration building of a university was experiencing major pigeon problems in their loading dock. The pigeons were leaving such a mess that workers were afraid to walk on the stairs that ran beneath the pipes, the area where the pigeons were occupying.

The university did not want to use any type of poison as the chemicals are not only harmful to the animals, but they could pose a public relations problem for the university.

Dura-spike, was used across the pipes that the birds were landing on to get rid of the problem. The spikes were a success and proved to be very effective.

Installer Goes The Extra (Five) Miles With Dura-Spike Bird Spike

One of Bird Barrier’s factory-certified professional installers sent in these photos of a recent job in an industrial warehouse. Pigeons were perching in the piping and conduit running the length and breadth of a large warehouse. Factoring the size of the building, an exclusion strategy was a logistical nightmare and prohibitively expensive for the client. Instead, the installer used Bird Barrier’s all-stainless steel Dura-Spike bird spike to remove all the available overhead perching areas. The entire project used over five miles (eight kilometers) of spike and Bird Barrier Bond industrial adhesive. The pigeons have since left the building and are looking for another, less pointed, roosting area.

Dura-­Spike Bird Spikes Solve Problems Large and Small

Dura-Spike Bird SpikesThe nice thing about Bird Barrier’s Dura-Spike bird spikes is that it is fast and easy to install on both large and small jobs. Because it can be glued or screwed to both flat and curved surfaces, it is an ideal solution for pigeons in non-nesting environments.

Take for example the two jobs done recently by two different PMPs. One involved about 3,500 linear feet of the product on standard parapet caps and windowsills, while the other used only about eight feet on five metal satellite dishes.

The Large Job

The building owner wanted a long lasting solution and liked the fact that Dura-Spike is 100 percent marine grade stainless steel. Its three-foot lengths are fast and easy to glue down to the surface, and so the installer was able to offer a very competitive price due to the relatively small amount of labor required.

Dura-Spike Bird SpikesThe project used all three models of the Dura-Spike; Narrow (2.5″) for windowsills, two rows of the Wide (5”) on the parapet caps, and some Xtra-Wide (8″) on wider ledges. It was glued down with Bird Barrier Bond so there was no need to penetrate the building with screws that might later cause leaks.

Two men glued down the 3,500 feet in about 50 man-hours.

The Small Job

A company with five large satellite dishes on its roof was annoyed at the droppings from pigeons. As they perched on the lips of the dishes, they made their messes on sensitive equipment that needed to be constantly cleaned.

Dura-Spike Bird SpikesAgain, the customer liked the idea of an all-metal solution and chose Dura-Spike over other spikes with plastic bases, or all plastic designs. And, because they are round the thin base of the Dura-Spike would follow the curve perfectly.

Due to the thin edge being mounted to, the installer chose to use stainless steel screws. He first drilled into the metal frame, then drove in the screws as can be seen in the accompanying photograph. He used every other screw hole in the base. Luckily the dishes could be unlocked and rotated, so he was able to do the job without getting up on a ladder. Each of the five dishes took less than an hour to install so the job was done before lunch.
