Moderately ineffective
I LOVE the smell of this product and have yet to get an imbedded tick during its trial, but it does not repel ticks and it certainly does not repel mosquitoes or black flies. Scent driven insects appear to be moderately deterred for a short period of time but even the dog gets bites while using it.  I had high hopes for this product.  I've used it to spray in my closet and on my dirty clothes pile with some results as a short term deodorizer.
