How to Prevent Squirrels from Chewing on Garden Furniture

Chewed chair legs, roughened table edges and missing patches of varnish can make outdoor furniture look as though it has been attacked overnight. In Australia, however, the animal responsible may not be a squirrel. Possums, rats and cockatoos are far more common garden visitors, while established squirrel populations are unusual on the Australian mainland.

Correct identification matters because each pest responds to different controls. Look for fur, droppings, tooth marks, climbing routes and the time of day when damage occurs. Once the visitor is known, a combination of furniture protection, food management and humane deterrents can help preserve an outdoor setting without harming native wildlife.

Confirm what is causing the damage

Squirrels usually leave paired incisor marks on timber, with shallow grooves or scraped areas around corners and narrow edges. They may also bury food in pot plants, dig through loose soil and move quickly along fences, roofs or tree branches. Fresh damage often appears on softwood, untreated timber and furniture with exposed end grain.

Possums tend to make larger, irregular gnaw marks and may leave droppings beneath the furniture. Rats often work at night and target wicker, plastic, stored cushions and softer timber. Cockatoos can remove surprisingly large pieces from wooden furniture, particularly when they are already visiting a garden for seeds or fruit. If the animal is unfamiliar in a suburb such as Melbourne or Sydney, contact the relevant state biosecurity or wildlife authority before attempting to trap or relocate it.

A simple phone camera can help. Photograph the marks beside a ruler, inspect the area after dusk and check nearby trees for scratches, nests or feeding remains. Do not handle an unfamiliar animal, and never use poison where pets, children or native animals could reach it.

Remove the attractions around the setting

Outdoor furniture becomes more appealing when it is close to food, shelter or a reliable water source. Sweep up fallen fruit, secure rubbish bin lids, clean barbecue grease and avoid leaving bowls of pet food on the verandah overnight. Bird feeders can also draw rodents and other animals directly towards tables and chairs.

Trim branches that create an easy bridge from a roof, fence or tree to the furniture. Keep climbing plants away from the patio and move stacked timber, garden tools and unused pots away from walls. In many Australian homes, alfresco areas are used for regular weekend entertaining, so a quick clean after a gathering can remove crumbs and food smells before pests investigate.

Small gaps around sheds, decks and storage boxes can provide a nearby hiding place. The advice in this guide to seal small holes is also useful for reducing access to enclosed storage areas, although ventilation openings should remain protected with suitable mesh rather than blocked completely.

Make timber and synthetic materials less tempting

A sound finish is the first physical barrier for wooden furniture. Sand rough edges, remove loose coating and apply an exterior-rated oil, stain or paint according to the product instructions. Pay special attention to legs, corners and the underside of table rails, where damage may go unnoticed. Recoat as recommended, especially in hot, sunny locations where ultraviolet light quickly dries and weakens timber.

Hardwoods and recycled plastic can resist chewing better than soft pine, but no material is completely pest-proof. Metal leg caps, corner guards and replaceable timber blocks can protect the parts animals repeatedly target. For woven furniture, use a fitted cover rather than relying on a spray coating that may crack or transfer to clothing.

Australian conditions make routine maintenance particularly important. Coastal salt air can accelerate corrosion, while intense summer sun can make plastics brittle and fade painted surfaces. In Perth, Adelaide and other dry areas, water restrictions may also mean that dusty patios and garden beds receive less frequent washing, allowing food residue to remain. A damp cloth, mild detergent and regular inspection are often more useful than strong chemicals.

Use humane deterrents and secure covers

A fitted outdoor furniture cover removes access to the most attractive chewing points. Choose a breathable, weather-resistant cover with tie-downs, and avoid loose fabric that could become a nest or flap against the furniture. Store cushions in a sealed deck box or shed, raising the box slightly from damp ground and checking it for gnawing before each use.

Motion-activated lights or sprinklers can interrupt an animal’s routine without injuring it. Vary the position of deterrents every few days because persistent pests may learn that a fixed device presents no real threat. Commercial taste repellents can work on some surfaces, but test them on an inconspicuous area first and check that the label permits use around pets, food-preparation areas and native wildlife.

Strong chilli, mothballs, glue traps and poisons are poor choices. They may injure non-target animals, contaminate surfaces or create a risk for pets. Australian wildlife protection rules differ between states, and relocating a trapped animal can be illegal or harmful because it may be separated from its territory. If damage continues after food and shelter are removed, use a licensed wildlife or pest professional familiar with local regulations.

Protect the whole outdoor area

Furniture damage may be a symptom of a wider access problem. Inspect pergolas, eaves, rooflines and fencing for routes that allow animals to reach the patio. Secure loose screening with galvanised mesh, repair damaged gates and keep climbing branches pruned below roof level. Any repair should allow the animal to leave before an opening is closed, particularly if young animals may be inside.

Doors and windows can also become weak points in a covered entertaining area. A door that rubs or fails to latch can leave a shed or enclosed porch open, so guidance on fixing a sticking door may help with the basic adjustment before replacing hardware. Check flyscreens for tears and make sure pet doors have a secure closing mechanism.

Heat can influence how often an outdoor area is used and how quickly finishes deteriorate. Window treatments that reduce solar load, such as the options explained in this guide to energy-saving window film, can make enclosed patios and sunrooms more comfortable. Keeping these spaces cooler may also reduce the temptation to leave doors open throughout the day, limiting access for opportunistic pests.

A weekly inspection is usually enough to catch new gnawing before major repairs are needed. Check furniture legs, covers, storage boxes, nearby branches and droppings, then record where each sign appears. If the pattern changes after a deterrent is moved, continue with the measures that interrupt the animal’s route rather than adding harsher products.

The most reliable approach is simple: identify the visitor, remove food and shelter, protect vulnerable furniture, and block access only after animals have safely moved away. For an Australian garden, humane exclusion and regular maintenance provide a safer long-term defence than poison or improvised traps.
