Bird Proofing Your House or Boat

by Alex A. Kecskes

Pest birds have, for years, taken their toll on homes and boats. Pigeons, seagulls, crows and all manner of pest birds have invaded private property to wreak havoc, destroy and devalue our prized possessions.

Homeowners have had to put up with damage to roofs, gutters and air conditioning units. Any homeowner who has ever had to clean nests and debris out of a gutter knows it's not a pleasant task. Neither is cleaning bird droppings off a solar panel or dish antenna something to look forward to. Any air conditioning repair person will tell you that bird droppings can stop and stall even the most expensive air conditioner.

Boat owners have long had to deal with pest gulls and other annoying birds. Sails and sail boat covers splattered with bird droppings are no fun to clean. In some cases, if the bird droppings aren't removed, the damage to canvas covers can be permanent, causing them to rip and tatter. Damage can be equally serious and permanent to sonar, radar and radio antennas and their motors and mountings. This gear is not cheap to repair or replace. And what boat owner hasn't been obligated to apologize for bird droppings on a deck, step or side runner after a guest has slipped and taken a bad fall. Not to mention the legal liability of such an accident.

Bird Proofing Devices and Solutions

Advances in bird proofing technology have resulted in some very effective and humane pest bird deterrents. These run the gamut from high tech to low cost. Most are easy to install and maintain. 

Bird Spikes Keep 'Em from Landing

A widely used bird deterrent, Bird Spikes are popular among property owners, boat owners and municipalities. The spiked strips look like they would impale whatever comes near them. Not to worry. The blunted spikes are safe for birds, pets and humans. Bird spikes have an uncanny ability to dissuade pest birds from landing. The spikes come in durable stainless steel or stiff, unbreakable polycarbonate. For seagulls, there's a spike called the Mega Spike. So named because it sports some very big spikes--typically 7” high. The best mega spikes are made of marine grade stainless steel. Other spikes come with a crush-proof, non-reflective metal finish. Spikes with a U.V.-protected polycarbonate base will last longer. You can even get angled spikes to accommodate curved surfaces.

Most buildings today have rain gutters where birds tend to gather and nest. When water backs up, it seeps under roofing tiles and shingles, which can lead to expensive roof repairs. Enter the Gutter Spike. It's the ideal way to bird proof against pest birds that love to gather in rain gutters. The spikes have adjustable clamps at the base so they can be easily attached to the lip of a gutter.

Slippery Slope

Simple, humane and highly effective, Bird Slopes are basically just angled PVC panels that won't allow pest birds to get a solid footing when they try to land. It's the ideal bird-proofing device for eaves, ledges, beams and other similar niches. Bird slopes are easily installed on almost any surface using nails, screws or glue. They are virtually maintenance free. And they come in a number of different colors to match your exterior décor.

Gone with the Goo

Birds hate to land on sticky surfaces (like we hate to get gum on our shoes). Bird Gel is the bird proof solution that really annoys most birds. The stuff pumps onto any surface with a standard caulking gun, and when it dries, it stays sticky for a long time--about six months. Pest birds land on it and it tugs at their little feet, step after annoying step, until they can't wait to leave.  Gels are ideal for use on ledges, conduit, pipes, I-beams and parapet walls.

The Net Difference

Barrier deterrents have long been an effective and humane bird proofing solution. One of the best barrier deterrents is Bird Netting. It comes in several net mesh sizes to deter various types and sizes of pest birds. The best bird netting is flame resistant, U.V. stabilized, and rot- and water-proof.

Create an "Optical Distraction Zone”


Bird Scare deterrents have a long and successful history as effective bird proofing devices. These simple reflective foils, shiny tape banners and balloons work because they create a zone of optical distraction that birds just don't like to be around. Some produce a snapping noise in the breeze that adds to the distraction factor. One note about bird scare deterrents: They need to be moved around and replaced every so often or pest birds will get used to them.

In a Class by Itself

Considered the king of bird scare devices, Scarecrows are the ultimate bird-proofing weapons. Humane and highly effective, these innovative devices deter pest birds using a clever blend of technology and bird psychology. Basically a motion-activated sprinkler, Scarecrows deliver a sudden blast of water spray whenever they sense a bird flying or walking near them. Best of all, they combine this sudden water blast with the Scarecrow's moving head and sprinkler sound, which is something pest birds will never forget.
