Mosquito-repelling plants?

Question

Is there such a shrub or even a tree? Perhaps a plant of which you can grind the leaves or use the sap to make a resin that would repel insects when burned on charcoal (like incense)

Answer 1

Basil, pyrethrum, geraniums, rue (the last one keeps away cats, too!) have been said to have insect-repelling properties. Citronella grass contains an oil that is used in mosquito repellants.

Answer 2

These are all mosquito repelling plants Catnip, Rosemary and Marigolds.  Maybe dried Catnip or Rosemary would be the go.
