Peppermint, vanilla, bay, clove, sassafras, and cedar have all been used as bug repellents. Make your own potpourri from these great smelling naturals or make arrangements of fresh eucalyptus leaves. Open a bottle of Pennyroyal essential oil and watch the mosquitoes take off. You can purchase Pennyroyal usually from any stores that sell herbs or essential oils. Buy citronella candles or by the bottle.
Mosquitoes hate it.
Set mosquito traps around your home by putting water in a bucket and add a good measure of dishwashing soap. When the mosquito lands to lay her eggs, she won't be able to escape from the slick emulsion. Plant a barrier of tansy or basil near doorways or around outdoor patios. Mosquitoes as well as flies and ants are repelled by them. If you're having a barbecue, throw some sage and rosemary on the coals to repel mosquitoes.
