The smell emitted by the plant is irritating for mice and they try to avoid them. Poo from bobcats, snakes, and cats are also effective mice deterrent because of their distinct smell. That smell scares mice away due to their natural fear on their predators. Pet stores have products that contain this unique smell which you can buy to spread over your house to keep mice away.
1) A myth exists that a cucumber smell comes from rattlesnakes. 2) The Tongue Mountain Range is known for harboring rattlesnakes. 3) The only place I have ever smelled random cucumber is the Tongue Mountain Range. Which leads me to believe the tiny minority, that rattlesnakes do in fact give off a cucumber smell.
The picture above shows the citronella plant; also called Pelargonium citrosum. This geranium is unrelated to the true citronella. Not only that but the scientific name of the plant is not even recognized as a valid name. It is a geranium (ie Pelargonium) and it sort of smells like citronella.hey did not study how the catnip extract worked on humans to repel mosquitoes. They did not determine if there are any side effects of having catnip extract on skin â does it irritate the skin, for example. I could only find one obscure product that contained catnip, and it contained 3 other active ingredients.
