Chacma baboons raid homes along the Garden Route all year round. Property owners from Hermanus through Knysna to Plettenberg Bay face the same question: how do you keep baboons out without sealing every window shut and losing the ventilation that keeps coastal homes mould-free?
Why the Garden Route Baboon Problem Is Persistent
The chacma baboon population across the Western Cape has grown to more than 600 individuals, according to the City of Cape Town’s 2024 baboon management data. That pressure extends well beyond the Cape Peninsula. George Municipality, Knysna Municipality and the Overberg region all report ongoing baboon incursions into residential suburbs.
The problem is not seasonal. Troops raid residential areas throughout the year. Pressure can intensify during certain months when natural food sources tighten, but baboons visit homes whenever food, shelter or opportunity is available. Open windows, unlocked doors and unsecured bins become targets in every month of the calendar.
Hermanus, Betty’s Bay, Rooi Els and Pringle Bay are hotspots. So are Wilderness, Sedgefield, Knysna and Plettenberg Bay. Baboons in these areas are not vervet monkeys. They are chacma baboons, larger, stronger and far more destructive when they enter a home.
What Scares Away Baboons and What Actually Works Long-Term?
Deterrents help in the moment. Water pistols, loud noises, toy snakes. Local municipalities recommend all of these. The problem is they require someone to be home.
Holiday homes sit empty for weeks at a time. A scare tactic only works if a person is behind it. Yet an empty holiday home still needs ventilation. Sealed-up coastal properties develop mould and mildew within weeks in the humid Garden Route climate. The owner arrives to a house that smells damp, feels damp, and needs airing out before it is usable.
Long-term baboon proofing means physically preventing entry while keeping air moving through the house. The two main approaches are security mesh screens and window locks that restrict the opening gap.
Security Screens vs LockLatch®: Cost, Aesthetics and Practicality
Custom Blinds in Knysna, Corner Star and Sheer Guard all offer baboon-proof mesh screens. These screens are effective. They are also expensive. A full-home installation along the Garden Route typically costs R40,000 to R80,000 depending on the number of windows, with individual windows running R3,000 to R6,000 each.
The screens are permanent. They block views. They require professional installation.
LockLatch® takes a different approach. It is a C304 stainless steel latch that restricts how far a window or door can open. The gap is adjustable between 9 and 17cm. That opening is too narrow for a chacma baboon to pass through, but wide enough for genuine ventilation that keeps holiday homes mould-free while they are unoccupied.
LockLatch® fits any window or door whatever the frame is made from and whichever way it opens. Installation is a DIY job that takes about 15 minutes per window. The fixing method uses one-way security screws on wood and steel frames, or pop rivets on uPVC and aluminium. Four small holes are drilled into the frame, then secured using either a screwdriver or a rivet gun depending on the frame type. No structural modification. No professional installer required.
The effective opening is slightly narrower than the 9-17cm nominal range because the footplates usually mount to the middle of the frame rather than the very edge, reducing the practical gap by roughly 3-4cm. For baboon exclusion, that tighter gap is an advantage.
How Does LockLatch® Work on Holiday Homes Left Unattended?
A lockable pin secures the arm in position. The pin uses a removable key, so the setting cannot be changed accidentally or by curious wildlife. Set it before you leave. The window stays locked open at your chosen gap until you return.
C304 stainless steel is rust-resistant, which matters along the Garden Route coast where salt air corrodes lesser metals within months. The product carries a lifetime guarantee and requires minimal maintenance.
LockLatch® is a DIY product costing less than R1,000 per window or door. A homeowner in Knysna baboon-proofing 10 windows would spend less than R9,000 on LockLatch® units, compared to R30,000 or more for custom mesh screens across the same windows. The cost saving goes straight to the bottom line, and the installation can be done over a weekend without booking a contractor.
Are There Baboons in Knysna and Plettenberg Bay?
Yes. Knysna Municipality runs an active baboon control programme. Plettenberg Bay, Sedgefield, Wilderness and George all fall within chacma baboon territory. Activity varies from street to street, but the problem is present throughout the year rather than isolated to a few winter months.
Community pages for Garden Route residents document weekly incursions across the seasons. Members regularly share damage reports from homes left with open windows.
The Practical Steps to Baboon Proof a Garden Route Home
Start with the windows baboons can reach. Ground floor and any window accessible from a wall, tree or roof overhang. Baboons are climbers.
Fit LockLatch® to each of these windows. Set the gap to the narrowest comfortable setting. Secure the pin. Test that the window cannot be forced wider from outside.
For doors, use the same approach. A LockLatch® on a sliding door restricts the opening to the set gap, allowing air circulation while physically blocking entry. For a holiday home, this is the difference between returning to a fresh, ventilated property and returning to one that reeks of damp.
Complement LockLatch® with baboon-proof bins and avoid planting fruit trees near the house. Remove bird feeders during high-activity periods.
