We're not here to scare you, but Waste Less Yorkshire has thrown in a dirty little secret: "The first thing you need to know about rats is that they like warm, quiet, safe spaces to live."

As it turns out, compost heaps and bins can warm up to a snug 40C – all part of the decomposition magic – creating the perfect pad for pests such as rats. However, fear not, for there's a way to prevent these lodgers from settling in.

Gardener's World said: "Watering the heap regularly can deter [rats]", as their aversion to damp digs is well-known. The sweet spot for compost moisture?

Think of it like squeezing a dish sponge, advises Hampshire City Council – not too soggy, not too dry.

If your heap does become overly drenched, toss in some 'browns', like dry leaves or hay. On the flip side, if it's looking parched, a splash of water or a helping of 'greens', such as veggie leftovers and coffee grounds should do the trick.

Replenish Oxfordshire concurs, advising to "make sure your compost contains enough moisture, as a dry compost pile is an ideal nesting site and shelter for rats".

Regularly turning the compost not only aerates it but also discourages rat infestation.

East Sussex County Council also suggests to "disturb your bin" by giving it a shake whenever you walk past. They further added: "Rats might not be so keen on hanging around if there is activity around the bin."

Lining the base with chicken wire could also be beneficial. If these tips don't deter the rodents from making your garden their abode, the Royal Horticultural Society advises eliminating "any accessible food sources, for example by making sure bins are sealed".

They further stated: "When feeding wildlife such as birds, do not let access food build up (this will also help reduce the risk of spreading wildlife diseases). Removing clutter will reduce hiding and nesting places for these animals."
