OFF! Outdoor Fogger 16 oz

Q: Does this work on keeping house flies and bees away during a picnic?

I'VE NEVER USED IT AT A PICNIC. I DID USE IT TO PULL WEEDS IN MY GARDEN AND IT DID NOT DO ME ANY GOOD. LARGE CITRONELLA STICKS ARE THE ONLY THING THAT HELPS ME.

Q: How long does it last before needing reapplied?

Only 4-6 hours. Perfect for an outdoor activity like a party or cookout. We usually spray about an hour before our guests arrive, this was it will dry in time. Works great for intended purpose!
