Priya I feel your pain! That's why I only use suet sandwich and hummingbird feeders.I have never used seed feeders I do plant native plants.
Like Penny I had an awful vole problem and when the summer comes I will have an awful chipmunk problem. I am not a handy person but I would like to put up a screech owl nestbox because Owls love to eat voles that's their main food I heard a screech owl last summer at night calling very close to the house but I haven't heard him since I would like to put up some boxes for the screech owls The other day while outside raking I heard then saw a red tail hawk flying above I think they love rats too.
