A straightforward adjustment to your bird feeder could eliminate the threat of rats invading your garden.

Installing a bird feeder in your outdoor space will likely attract numerous feathered visitors – however, without proper precautions, you may inadvertently welcome some unwanted guests.

Rodents such as rats and squirrels cannot distinguish that the food intended for robins or tits isn’t meant for them, and will rapidly devour whatever has been placed in your feeder.

Given that virtually nobody wants to encourage a rat infestation in their garden, careful consideration must be given to how you use your bird feeder.

Similarly, predators including cats and foxes may be drawn to the provisions in your feeder, potentially resulting in the deaths of the very birds you’re hoping to attract to your garden.

They are opportune scavengers and will take advantage of rubbish left out for collection. There numbers will increase if there is a plentiful supply  due to build ups of rubbish due to industrial disputes involving local government collections. Brown Rats carry many nasty diseases which they can spread to humans, normally through their urine. including; Leptospirosis or Weil's disease, Salmonella, Listeria, Toxoplasma gondii and Hantavirus. Brown Rats can inflict a great amount of structural damage. Rats feed on grain and may be attracted to your garden by fallen food from bird feeders. Stop feeding birds if you suspect rats are visiting your garden and secure chicken runs. Store bird and other animal food in secure containers.

Frequently, both predators and rodents are lured to your bird feeder due to one widespread error – though fortunately, this can be easily corrected, according to experts.

Speaking to Ideal Home, specialists revealed that a significant mistake many people make regarding bird feeders occurs before purchasing one.

Buying a feeder with the wrong shape can make it readily accessible to rats or squirrels – who possess excellent climbing abilities – as well as cats and foxes.

For those concerned wildlife is depleting bird feed before feathered visitors get a look-in, there is a wide range of squirrel and rodent-proof feeders available on the market. “

If food is really hard to find in your area,” explains expert Thomas Hibbert from the Wildlife Trust, “you could offer some seeds or suet in a squirrel-proof feeder”.

The most effective options to purchase are “weight-activated, caged, and domed” bird feeders, particularly for those wishing to deter pests and predators from their garden.

That said, for those reluctant to splash out on specially designed equipment, experts suggest there are a handful of alternative approaches worth considering.

Squirrels and rats will typically eat whatever is left out for garden birds, but introducing certain unwelcome ingredients can put them off entirely.

Sunflower or niger seeds, for instance, are firm favourites with birds but hold little appeal for squirrels.

Additionally, certain items can be added to feeders that produce such an off-putting odour for squirrels and rats that they will give them a wide berth altogether.

Rodents are strongly repelled by garlic, pepper, cayenne pepper, and peppermint, so scattering these amongst your bird seed could prove highly effective.

“While these smells are unappealing to rodents, birds can’t actually taste them, so sprinkling a little cayenne pepper into your bird feeders, for example, will act as an additional deterrent,” the experts claim.
