The great horned owl is found from the Arctic to the rain forest and from barren deserts to neighborhood backyards. It has a body length of 18 to 25 inches with a wing span up to 50 inches. These large predatory birds can weigh up to 60 lbs. There are many reasons for wanting to eliminate this bird from your home. Their prey is as diverse as rabbits, raccoons, armadillos, porcupines, chickens and domestic pets. They have no natural predator. They kill, cause structural damage and leave droppings that have adverse health effects for people.
Install bird spikes on rooftops and eaves to deter great horned owl nesting. Spikes are made of stainless steel or polycarbonate and last a lifetime.
Apply bird-proof gel on rafter beams. You can use this gel on hundreds of indoor and outdoor spots where these owls land or nest. It is a long-lasting, tacky bird repellent.
Use bird netting to keep owls out of structural openings and other possible roosting sites. It is a tough netting which will not deteriorate or lose strength when used outside. Be certain no owls are in the structure when you install the netting.
Install iridescent tape which uses sight and sound to keep birds from the selected area. The tape flickers and shines in sunlight, disorienting birds. It also emits a threatening sound as it flaps in the wind further keeping birds away. It installs easily and lasts for years.
Use electronic repellents for residential areas. They emit ultrasonic sounds, inaudible to humans, to keep owls from any outdoor area around the home.
Repel persistent owls with scarecrows. Move the scarecrows regularly and set off loud sounds such as shotgun fire or fireworks when you spot an owl.
