Not only that, but they can also spread diseases, posing serious risks to birds. can eat large quantities of seed, damage feeders, and even scare away the you're trying to attract. But according to Green, there are four natural deterrents that can help keep at bay: eucalyptus, citronella, cayenne pepper, and peppermint.

"These strong scents are unpleasant to rodents," he explains. "They offer an organic defense when placed near bird feeders."
Try soaking cotton balls in essential oils or sprinkling pepper flakes near the base of feeders.
To further protect your feeders, use spill-proof designs that prevent dropped seed from attracting pests.
"Platform trays make it easier for rats to feed," Green warns. "Go for enclosed or tube feeders instead."
Seed-catching trays and regular sweeping can also reduce mess and remove food sources.
Installing baffles on feeder poles is another proven way to stop rats climbing up to access seeds.
Green also advises choosing metal feeder poles over wood or PVC, which rats would otherwise climb on and chew.
Finally, avoid overfilling feeders, as excess seeds often spill and draw rodents in.
Don't forget to store bird food in sealed containers to help prevent rats from entering sheds and garages.
Check the area regularly for signs of rat activity, like droppings or gnawed plastic.
And avoid leaving out leftover pet food, compost scraps, or open rubbish bins near the feeder area.
Combining good hygiene with smart feeding habits will help protect the birds - and your garden from rats.
