Birds appear to not be phased by the scent of sturdy spices like peppermint, however rats are extra depending on their sense of scent to discover a meals supply. Contemplating this, there are two ways in which peppermint works to discourage them. First, when current, a rat is not going to go close to that meals supply as a result of it would not scent appetizing to them.
Secondly, the scent itself works to masks the presence of the chook meals. Since rats are opportunistic munchers, they aren’t prone to know there’s tasty meals within the birdfeeder. They’re typically going to hunt out the simplest entry level as an alternative. When near the bottom and filled with seed, particularly from birds who drop greater than they eat typically, rats are drawn to that space in the event that they scent the goodies. If you happen to see a number of rats at your birdfeeder, peppermint oil is an effective place to begin, however for a big infestation, this will likely not work as effectively. It does work very effectively as a kind of prevention technique. If you realize rats are close to your feeder, use this as a strategy to maintain them from making your chook meals a buffet.
