The Least Toxic Ways to Protect Yourself from Ticks
When it comes to keeping away creatures that creep and crawl, the U.S. doesn’t mess around. More than 198 million Americans used insect repellent last year, a figure that is expected to top 200 million this year. Much of that is to ward off ticks, which are technically arachnids and carry more than a dozen diseases. But the repellents themselves can present concerns of their own with their pungent smells, occasional irritation, and labels full of mystifying chemicals most people have never heard of. [time-brightcove not-tgx=”true”] With 2023 turning into one of the worst tick seasons in recent memory, pl...

Acaricidal activity of essential oil of Syzygium aromaticum, hydrolate and eugenol formulated or free on larvae and engorged females of Rhipicephalus microplus
Abstract The cattle tick, Rhipicephalus microplus (Canestrini, 1888) (Ixodida: Ixodidae), is the most important ectoparasite in cattle‐breeding areas and is responsible for severe economic losses. Synthetic acaricides have been used to control this parasite. However, the need for safer products has stimulated the search for new acaricides, such as those to be obtained from medicinal plants. The essential oil of Syzygium aromaticum (clove) has many biological properties and shows great potential for use in veterinary applications. In the context of the need for new agents, this study investigated the in vitro properties o...

Evaluation of Clove Oil, Icaridin, and Transfluthrin for Spatial Repellent Effects in Three Tests Systems Against the Aedes aegypti (Diptera: Culicidae)
One essential oil (clove oil), one skin repellent (icaridin), and one insecticide (transfluthrin) were tested for spatial repellent effects against non-blood-fed female Aedes aegypti (L.) mosquitoes. The compounds were tested in acetone dilution series using a Y-olfactometer, a double cage system, and a double room system. All compounds exhibited spatial repellent effects at certain concentrations. Clove oil required relative high dosages to cause high effects (Y-olfactometer 6 mg, double cage 60 mg, and double room 1,200 mg). The dosages to achieve comparable results with icaridin were lower (Y-olfactometer and double cag...
