this bottle ma be only 4 oz, but it makes 8 gallons. most products may be 8 oz but only make 2 gallons. so the cost is well worth it. also can be made as a dip, spray, or drench over the back of animal. EXPERIENCE AND KNOWLEDGE!
worthwhile product. We have a signif flea problem. I made the dip up at highest maximum strength as per the bottle and dipped puppies of age 4 weeks and above. The flea and tick kill was rapid and 100% . Need to keep the dip out of eyes nose and mouth. Puppies had no ill effects but also mouth nose and eyes carefully protected. I reduced rating by 1 star becasue of high cost for small bottle (item is overpriced for size) and duration of protection is not as long as desireable. But will use it again when needed.
