yep as simple as veggy or olive oil but DONT OVER DO IT! just a drop or two and it drowns those pesty little mites
as for as Mosquito there is something called the Mosquito Barrier and is a variation of Garlic Barrier. Mosquito Barrier kills and chases mosquitoes, ticks and fleas out of the yard and away from the house immediately upon spraying and keeps them out for 4 weeks and longer. Spray onto grass, shrubs, flowers and any trees in the area. Safe for children, pets and plants.
