Does it work for everybody?
No. Every now and then there will be a person whoes body chemistry decreases the effectiveness of Shoofly Soap and Spray. No-see-ums are the most challenging insect we deal with. I would say works 95% of the time.
How much do I need?
One bar of Shoofly Soap is enough for one person to use and repel black flies for the entire season. The amount of spray you need totally depends on how you're using it and I can't predict how much you'll need.
Can Shoofly products be used with sun screen?
No. The fragrance of the sun screen can render it ineffective.
Must Shoofly Soap or Spray be reapplied after you've been in the water?
Yes. Shoofly products are not waterproof.
How long does it last before you have to reapply it?
It depends upon several factors. How much do you sweat? Your personal body chemistry can affect how long it lasts. Were you in the water? If the no-see-ums start to bother you just reapply it.
Do I need to use both the soap and the spray?
No. But it's best if you do. Shoofly Soap puts a higher concentration of ingredients on your skin than the spray. Use the spray on your hat, the ends of your sleeves, and around your socks. Having said that, a lot of people use the spray only and are completely happy. But from my own experience, if I had to have one or the other, I would want the soap.
Are some people bothered by no-see-ums more than others?
Absolutely. You can have four people standing on a golf course and have one constantly being bitten by no-see-ums while the others are not. It's a matter of body chemistry. Fortunately Shoofly Soap and Spray work extremely well for the vast majority of people with that "oh so special" body chemistry.
What else can I do to help keep no-see-ums from bothering me?
Avoid dark colored clothing like dark blue or black.
Does Shoofly Soap and Spray smell bad?
No. I've only had two or three complaints about the fragrance. Most people actually like it. But no... you're not going to smell like insecticide. All the ingredients in Shoofly Soap and Spray can be found in most kitchens.
Can Shoofly be used on dogs?
Yes! We have had excellent results using Shoofly Spray to repel black flies and deer flies on dogs. I have not had any specific reports regarding repelling no-see-ums from pets. But it worls well on people... it works well for biting black lies and deer flies... so it's reasonable to assume that it would work well for no-see-ums.
