Remove cacti, as well as thorny plants and bushes, on your property, as these are all attractive to the cactus wren. The bird uses these plants and shrubs to make a large nest and also relies on shrubs for foraging. Uproot plants and bushes if possible, and donate them to friends or your local park or wildlife refuge. Cactus wrens also look for food in rock crevices, so remove large rocks from your property if possible.
Keep a cat on your property if possible, as it will feed on adult cactus wrens. The birds may also be more inclined to stay away from your property if they smell a cat.
Use the urine of cactus wren predators, such as a bobcat, hawk, fox or coyote, to keep the birds off your property. Spread the urine around the property borders, as well as near any shrubbery and cactus plants.
Place a hawk decoy on the fencing or other applicable surface to deter cactus wrens.
