The Top 5 Pest Warning Signs Every Rural Landowner Should Know

Pests are a constant challenge for rural landowners across New Zealand. From rabbits tunnelling through paddocks to possums raiding feed sheds, rural pests can cause thousands of dollars in damage long before they're seen in broad daylight. While many people think pest problems are most visible during spring and summer, the early warning signs often appear well before a full-blown infestation takes hold.
At T & C’s Pest Control Services, we understand the real cost of pest damage - not just to land and livestock, but to time, productivity, and long-term farm health. The key to managing rural pests is early detection, and this blog will help you recognise the top five warning signs that pests may already be active on your property.
Fence Damage and Ground Disturbance That Reappears
One of the earliest and most overlooked signs of a pest issue is repeated, unexplained damage to fencing or soil. If you find fence lines pushed over, wires broken, or posts loosened in the same area multiple times, chances are it’s not the wind — it’s pests.
Feral pigs are a common culprit. They are strong, persistent, and highly destructive, rooting under or smashing through fencing as they search for food. Their damage often appears overnight and worsens if left unaddressed. Rabbits and wallabies also create clear trails or tunnels under or along fences, especially in areas near bush edges, gullies, or water access points.
If you’re regularly repairing fences, take a closer look. Fresh tracks, disturbed earth, or a clear path through the same section can indicate persistent pest activity.
Disruption Around Feed, Grain, and Storage Areas
Another common sign of pest presence is evidence of tampering or contamination near feed and storage areas. This can include:
Feed bags torn open
Spilled or scattered pellets
Droppings on or around feed bins
Chewed sacks or containers
Possums, rats, stoats, and even feral pigs will take advantage of poorly secured feed. Their presence doesn’t just mean lost food — it poses a biosecurity risk through contamination and disease transmission. Stored hay and silage can also become nesting zones if not monitored, leading to spoiled feed and potential health issues for your livestock.
If you find repeated mess or droppings in or around sheds, barns, or storage rooms, it's time to inspect further and consider action.
Slow-Growing or Bare Patches in Pasture and Shelter Belts
Early pest damage often shows up in the landscape itself. If parts of your pasture seem to recover more slowly, or if your shelter belts and young plantings are being stripped of bark or foliage, pests may be the cause.
Rabbits are notorious for grazing pastures to bare soil, especially in high-pressure areas like hill slopes or near cover. Wallabies and deer tend to browse new shoots, stripping bark and killing young trees in shelter belts or conservation zones. Over time, these pests alter land fertility and structure, often leading to erosion and pasture degradation.
Walk your property with an eye for unusual patterns in growth. If one paddock is struggling while others thrive, or if new plantings keep failing, there may be more happening than just poor soil.
Behavioural Changes in Livestock and Poultry
Livestock are often the first to know when pests are present - they just can’t tell you directly. Unusual behaviour in stock, such as avoiding certain paddock areas, gathering near fences at night, or showing signs of anxiety, could indicate predator activity.
Stoats, ferrets, and weasels are especially dangerous to poultry and game birds. They kill quickly and often in excess, with a single stoat capable of wiping out an entire coop in one night. Possums may also disturb animals, particularly at night, while pigs have been known to harass lambs and damage pasture where livestock feed.
If your animals are unsettled or laying off feed, consider whether there could be an unwanted visitor nearby.
Signs of Night Activity: Droppings, Tracks, Sounds
Most rural pests in New Zealand are nocturnal, meaning you’ll rarely spot them during the day. But they leave clear signs if you know what to look for. Possums leave large, tubular droppings and may be heard growling or thudding across roofs or trees. Rabbits leave smaller round droppings near burrow entrances or grazing sites. Stoats often leave drag marks, claw prints, and a distinctive musky smell near nesting areas.
Night-time scratching in the ceiling, rustling in the shed, or damage that appears overnight can all be indicators of active pest presence. Use a torch to check for reflective eyes or trails around feed sheds, bush edges, and paddocks.
Early Detection Is Key to Pest Prevention
The sooner you spot a pest problem, the easier and more affordable it is to control. Waiting until spring or summer allows pest populations to grow, damage to increase, and control efforts to become more intensive and expensive.
At T & C’s Pest Control Services, we offer professional property assessments to help identify and control pest issues before they escalate. Whether you’re concerned about signs you’ve seen or simply want to stay ahead of the problem, we can help you develop a practical pest management plan for your land.
