How to identify and deter uninvited guests in your garden
Rats are highly adaptable, social mammals that can thrive in both urban and rural Britain. From burrowing in compost heaps to raiding bird feeders, these intelligent pests can cause significant damage to your crops and even pose health risks to humans.
Identifying a rat infestation requires looking for specific physical clues. You might notice tunnels in the soil with entrance diameters of 3 and 40 mm, which are roughly double the size of those made by mice or voles. Their droppings are distinctive: cylindrical pellets, about 15 mm long and 5 mm wide, with rounded ends. If you see piles of snail shells, it may indicate rats have been preying on invertebrates in your garden.
The damage they cause is often found in the garden's food supply. Rats feed on a wide variety of crops, including sweetcorn, pumpkins, squash, and root vegetables like carrots, parsnips, and potatoes. They also target harvested fruits like apples and even seeds. You can often spot their presence by looking for parallel grooves left by their incisor teeth on food material. Beyond crops, they are frequent visitors to bird feeding stations and may consume food intended for pets or poultry.
Managing rats involves removing the elements that attract them. Alan Titchmarsh suggests making your garden an unattractive place by removing food sources and reducing clutter to eliminate nesting sites. Ensure bins are tightly sealed and avoid letting excess birdseed accumulate. Be particularly cautious with compost heaps; the light, friable nature of compost is ideal for burrowing. While you can use old compost, avoid applying it to raw-eaten vegetables like radishes or strawberries if the compost was previously inhabited by rats.
There are also health considerations to keep in mind. Rats can carry bacteria that cause leptospirosis, also known as Weil's disease. This is spread through rat urine and can infect humans through ingestion or via cuts and abrasions. Because rats breed year-round—with females producing up to five litters annually—proactive garden maintenance is essential for long-term control.
