A resident in Salt Rock, KZN, was dealing with twice-daily monkey invasions. Each morning the troop landed on his double-storey roof and taunted his four dogs, triggering barking and lawn damage as the dogs “chased” them around the house. The same pattern repeated most afternoons.

Monkey Bizness recommended an overhead ultrasonic unit on the upper roof.

Fourteen months later, the client reported the monkeys had stopped landing on the roof within a day or two of installation; the dogs had stopped barking and wrecking the garden; and birdlife on the property had flourished.

“And the monkeys don't take the eggs out of the nests… I’ve watched a Crested Barbet raise two sets of chicks.”

Asked if we could share his feedback, he said: “Use my name. I made a choice, it works and it’s a great product.” Know of any other monkey-repellent device that gets praise like that?
