If you're looked for the citronella scented geranium, your garden center should stock it. I remember seeing some at box stores last year.

Richter's herbs carry it. It's called Citrosa Geranium
�Mosquito Fighter�

For me however, can't stand the smell of citonella. instead I use mosquito dunks in ponds, but I would have to get these in the states

thanks.what are "mosquito dunks"anyway?

You can google it to see. They look like mini donuts which float in water. They kill off mosquito larvae but leave other animals unaffected.
