Repellent activity of catmint, Nepeta cataria, and iridoid nepetalactone
isomers against Afro-tropical mosquitoes, ixodid ticks and red poultry mites.
Interestingly, the chemical structure of nepetalactone
resembles some of the sedative components found in valerian root as well as some of the pheromones in tomcat urine, which produces similar behavioral effects to those seen with exposure to catnip in many cats.
Try Out Catnip Oil Believe it or not, the essential oil in catnip, nepetalactone
, repels mosquitos more effectively than DEET.
, the essential oil that gives catnip its distinct smell, is more effective than DEET at repelling mosquitoes, according to laboratory research conducted by Chris Peterson, an entomologist with the U.
Catmint, or rather the nepetalactone
in its leaves, mimics a feline hormone and acts like a recreational drug to cats.
Patience has started an agricultural and manufacturing initiative in civil war-torn Burundi in East Africa growing catnip to extract nepetalactone
, which is used as a repellent against malaria-carrying mosquitoes.
in catnip and pseudohypericin-hypericin in St.
The university has since patented the primary active ingredient in catnip oil, nepetalactone
, and its research foundation is working with unnamed companies to do human trials so it can be licensed by the U.
Scientists have discovered that nepetalactone
oil, which gives the herb its smell, is the strongest mosquito repellent known to man and ten times more effective than DEET, the chemical used in most repellents.
Catnip contains two forms of a chemical called nepetalactone
Iowa State University researchers Chris Peterson and Joel Coats report that cockroaches are repelled by two forms of the chemical nepetalactone
found in the catnip plant.
The researchers gave insects a choice of walking on either a piece of paper treated with nepetalactone
or untreated paper.
