Bottles may vary in looks but it will be the same product.  Based on the video about fleas, this product I buy from a local distributor.  They gave me training and I have been told and I do for my own home and salon dilute 2 ounces of this with 1 gallon of water.  
 
Buy the gallon sprayer if you need it.  
 
I personally use this product in my home and in my salon personally.
 
So, this bottle will last several sprays at the least!
