If your home has been besieged by gulls, you know what a nuisance they can be. These scavengers will eat just about anything that’s on your patio, boat dock or backyard. That includes fish, insects, mollusks, worms, mice, young birds, bird eggs, and berries. When gulls feast and gather, they'll leave an awful mess. They can cover your backyard and patio area with smelly, disease carrying droppings and rotting fish. If they use your rooftop to tear apart their prey, they can dislodge and damage roofing tiles and other rooftop structures.

Like most birds, it’s not just one type of gull you have to worry about. There are over 45 species of gulls. Your typical gull is a medium to large bird with a mostly white body and grey or black markings on the wings and tail. Their stout, orange bills and webbed feet make them easily recognizable. While gulls are often found near large bodies of water like bays, inlets and lakes (as well as the ocean), they have been known to venture inland for food. So don’t be surprised to see them on the roof of your home or patio if your home is miles inland. 
 
To keep gulls away from your home, you should first remove any open food source such as open trashcans or pet food. After that, you’ll need some effective bird control measures to keep them away. Here are three bird deterrents the pros use:

Bird Spikes for Gulls

Gulls regularly choose the roof of a home or structure to roost on. The peak of a roof is an especially desired area as it provides a nice look out point for food and predators. Bird Spikes are a humane product used to keep gulls off roof lines, parapet walls, pilings and other areas. Bird Spikes simply create an uneven surface that gulls know they cant land on. Spikes that are pre-assembled, such as the Stainless or Plastic versions are easiest to install.

Bird Spiders

Bird Spiders have spindly arms that whip about in the wind. Gulls see these and will simply move on to a friendlier landing perch. Bird Spiders are easy to set up on decks, posts, atop light fixtures, rooftops, fixed umbrellas and awnings. These bird deterrents are available in 2-, 4-, 6- and 8-foot arm lengths to create larger and larger areas of bird deterrence. Look for bird spiders that feature a glue-on base, which can be attached to most surfaces.

Sonic Gull Control

No gull likes to hear his fellow gulls being attacked. Or the sound of Peregrine falcons screeching in for the kill. Bird Sonic Deterrents exploit these fears and drive gulls away. These devices broadcast prerecorded distress and predator calls that resemble normal bird sounds to humans. One popular device features a built-in speaker that covers up to one acre. The unit can be programmed to turn on or off at night, and you can even adjust the volume.

Hirundo rustica!  It sounds like a battle cry of a foreign militia group. Actually, it is the scientific name for the common barn swallow.  Recognized by its long forked tail, glistening blue top feathers and soft pink breast color, the swallow can be seen flitting about almost endlessly throughout North America. One of the swallow’s most popular spots is California in the spring and summer.

Although these birds are pleasant to watch, they can create a nuisance in homes, structures, barns or stables.  Anywhere there are birds there is bird droppings.  In the case of swallows, their unique nesting habits add the additional title of pest bird.  Of the seven species of swallows that breed in California, the cliff and barn swallows build mud nests on the sides of homes, barns, garden gazebos, or stables.  These annoying mud nests often have landowners wondering how to keep these pest birds off their property.

Swallows look for structures that satisfy their four basic needs: an open area for seeking food, clean water for drinking and bathing, a vertical surface sheltered by an overhang for protection and attaching their nest, and, of course, enough good quality mud with which to build their mud nest. Once the birds find this perfect spot, they will come back year after year. 

The mud nests, just like the bird droppings can become infested with bugs or disease that can affect human health.  It is important to find humane ways to eliminate the nests and prevent the pest birds from returning the next year. During September and through January the swallows are still vacationing in South America, so now is the best time to install bird deterrents. Simply removing the abandoned nest will not deter these pest birds from returning.  In fact, removing nests during their “official” nesting season (mid-February to September 1) is not permitted in California without a special permit.

To keep pest birds away from a previously occupied nesting area, bird exclusion methods are required. Once the nest is removed and the area clean from debris, feathers and mud, use the methods suggested below to create a space that is uncomfortable and uninviting.  Bird Slopes under overhangs prevent the birds from getting a foothold on the vertical surfaces.  The UV protected slopes are a slippery, steeply slanted physical bird deterrent that blocks the overhang of the building.  These are ideal for ledges /overhangs that are about six inches wide. They are set in position and held in place with exterior polyurethane adhesive.

Hanging No Nasty Nest strips under eaves or overhangs are another effective way to keep birds away from the underside of overhangs or ledges. These are 3” x 11” strips of plastic that have a cluster of clear nylon strings dangling down.  Applying these irritating ticklers where the old nests used to be (or where new nests might be built) will coax pest birds to look elsewhere.

These simple bird control methods are aesthetically appealing and can be easily installed by the homeowner using adhesive, glue or nails.
