oil should work, its a very dangerous thing when it comes to this (for mites)
i dont think it drowns them as much as it just suffocates them.. coats them in a barrier of oil an doesent allow them to breath, or may get into their lungs and coat them..
Same reason you have to be carful with baby oil around children, can get into their lungs and suffocate them, so id be carful with oils around yur dog, they can get into em just as easily as children can |
