Exp Appl Acarol. 2016 Nov 4. [Epub ahead of print]

da Silva EM1, Rodrigues VD2, Jorge JO1, Osava CF3, Szabó MP3, Garcia MV4, Andreotti R5.
Ticks from Rhipicephalus sanguineus complex are widely distributed in the world and one species from this complex is the most common tick on dogs in Brazil, notably in urban areas. This tick is a vector of several diseases.
Among others it transmits the agent of canine Ehrlichiosis, a major dog infectious disease and the agent of Rocky Mountain spotted fever.
This tick can spread rapidly and develop intolerable infestations within no time.
Currently tick control is done with acaricides and demand for such drugs has grown fast.
However, R. sanguineus has already developed resistance to the main active compounds and the development of new acaricides is necessary.
Many essential oils of plants have acaricidal effect and may be an important source of molecules for the synthesis of new acaricide products.
In this study, we evaluated the effectiveness of a new herbal phytotherapic, consisting of the essential oil of Tagetes minuta L., against R. sanguineus in vitro and on dogs undergoing experimental infestations.
The product displayed 100% efficacy against larvae, nymphs and adults of the tick on all tested conditions.

Perhaps it is the stink that wards off the ticks! Some years ago, in an anti-orange phase, I tried to get them out of our garden, but they were very persistent, so I let them have their way! I love the orange now.

I love the orange now too. Works to get rid of ants inside if used regularly. Too bad marigolds don't smell like oranges!
