Pest control specialist shares 6 safe and effective methods to deter rats from your garden


Rats are usually unwelcome visitors in a garden and they are generally considered vermin, with the potential to spread serious diseases. Rats set up home beneath the decking, in sheds, greenhouses or compost heaps. spoke to Jordan Foster, Pest Control Expert at Fantastic Pest Control about the most humane and effective methods to get rid of rats and deter them from returning. 

Rats are nocturnal, so there is a high chance you might not see them scurrying around the garden, but there are other signs to look out for. 

Jordan shared the four signs you have rats in your garden; rat droppings, a pet acting strangely, rat burrows or rat bite marks. 

Rat droppings – The expert said: “It is very easy to spot rat droppings; they are a sure sign of an infestation. About 10 mm long, they are oval-shaped and resemble large rice grains.” 

A pet is acting strangely – “When there is an infestation, cats and dogs will be the first to notice,” he added. “Something is hiding if your pet stalks holes and crevices too much.” 

Rat burrows –“In addition to digging holes, rats make shallow tunnels,” Jordan revealed. “They are usually placed near food sources.” Look out for the burrows alongside walls, fences or buildings that are up to 10cm wide. 

Rat bite marks – “Rubber hoses are the most common thing you can find in the garden that rats gnaw on,” he said. “Teeth marks are a major warning sign of a rodent infestation.”

2. Get rid of all clutter 

“To get rid of rats, you need to remove all clutter that provides them with hiding places,” he added. 

“It may be enough for them to find your garden uninhabitable, even if you provide plenty of food. It includes the lawn as well. 

“Keeping high grass mowed regularly will prevent it from becoming a hiding place.” 

3. Remove water sources

“Rats, unlike mice, cannot survive without water,” Jordan said. While it’s not advisable to remove garden ponds, if you have a birdbath, remove it temporarily as “rats won’t stay for long” if there is no water source.  

Also, check your hose, or outside tap and fix any drips or holes. Secure drains too and add baffles to drainpipes.

6. Protect your compost bin 

For a few weeks, don’t add food scraps to the compost heap or bin, and include lots of green and brown materials instead to increase moisture content. You can also consider watering the compost heap as rats dislike wetness. 

To stop rats from digging beneath a compost bin and climbing inside, fix chicken wire around the base. 

It’s also a good idea to turn the heap regularly, but remember other wildlife use compost heaps too, so do it with care. 

Finally, if rats have made a home in your bin, don’t use the compost on edible crops.
