I have many plants in my balcony, around 20, and recently my Mom has noticed that rats are eating the plants. They finished Holy Basil in one night! All leaves are gone, even the buds. They are also munching on the new leaves of my Money plant.
How do I keep the rats off my plants?
The problem is we also get frequent visits from squirrels, but they are not of nuisance, at least to us. They don't eat plants. They just forage in the pots looking for something to eat. My mom is sure that the culprits are the rats, as she finds rat's poop scattered all around the Holy Basil and Money Plant.
We don't want to hurt any squirrels or pigeons or birds.
