Gardeners across the UK are being warned about the presence of rats following a sharp increase in sightings. According to Checkatrade, rats can carry diseases such as Leptospirosis, which may lead to Weil’s disease. The nocturnal pests are often found under decking, in greenhouses, sheds, and behind compost heaps.
Checkatrade experts advise looking for signs of infestation, including tunnels and runs along walls and fences, which are typically around 10cm wide. Gnawed wood and teeth marks on vegetables are also indicators. Prevention is key, and natural methods can help deter rats without resorting to exterminators.
Experts recommend keeping up with garden maintenance to reduce hiding spots, ensuring decking is airtight, and securing compost bins with chicken wire. Peppermint oil can be used to deter rats, as can lemon, citronella, and eucalyptus oils. Planting catnip is another natural deterrent. Covering or removing water sources, such as ponds, and using soil netting or strong polytunnels can also help.
To fill rat holes, Checkatrade suggests using cement, soil, dirt, gravel, mesh, chicken wire, or wire wool. Plugging holes at night when rats are away encourages them to find a new home. The experts emphasize that prevention is always better than cure.
In related pest news, ants are also common this summer. Experts from Hillarys recommend using lemons, cinnamon, or chalk to disrupt ant scent trails. Drawing lines of chalk around entrances can keep ants out without harming them.
