I ordered this refill because I've used YAYA tic ban and Squito ban for 3 years and I didn't want to ever run out. IOnce I noticed it was available in a concentrated refill
it was a very easy decision to buy it. Both of the YAYA products I've tried are 100% the most effective ones I've ever used and I'm outdoors, most of the year.
Before finding YAYA I had at least 3 tics that were imbedded, thus I needed a Doxyclclene perscription to hopefully prevent Lyme Disease.
Since I started using YAYA, tick ban I have never gotten even a single tick on me, and I only spray my legs or more accurately my pant legs both sides on each leg before going into any area likely to harbor ticks.
