Thank you for reaching out to us regarding our Insect Repellent Herbal Wipe-on Oil treatment. We understand your concerns about using an oil product and as we state and recommend in the instructions, a little goes a long way.
When applying this product, you do not need to use a lot at one time. We recommend applying a small amount on a more regular bases. Think of this product like a perfume or cologne. The scent is stronger at first and then will fade. Not to be applied like a teenager going to prom, ha ha.
Depending on the size of animal, we recommend pouring a small amount in the palm of your hand, rub them together to spread out the oils and then quickly wipe around the body. For medium to larger animals, we recommend splitting the body into sections. When finished applying the treatment, your should be able to smell it on them, but not really see that you put it on. You do not want to make them very oily.
I hope this helps you and others understand more how to use this product.
