I am looking for plants that repel knats and mosquitos
I have a huge mosquito problem and swarming knats. I am looking for plants that repel both, and ticks too. I am going to plant them randomly around the property and especially around the house.
I have 10 acres in Priest River Idaho and it is very rural. There is no standing water to explain the mosquito problem. I am trying to get a garden started (better late than never) but the bugs are enough to make a person go insane.
I got a list of some plants, like catnip and citronella grass and rosemary and marigolds. Rosemary as I understand it is a tropic plant and doesn't do well in cold. Catnip is zone 3/4, so would it survive up here? I can't find a source for citronella grass, or even much info on it.
Any help including other recommendations would be great. Chemicals are out of the question. I can't afford to buy massive amounts of assorted ingredients to treat even just the area around the house, so planting plants that are self sustaining and a one time cost is the best option for me.
