Thank you for submitting your question regarding Lupin. I recommend using Vectra 3D. This is a topically applied medication. The pests are repelled or killed on contact. This means the pet does not need to be bit for the medication to work as is the case with oral medications. It is a broad spectrum product including repelling mosquitos. This helps with heartworm prevention as well. I hope this information helps!
