Mortein does not live up to it's brand – I bought this product because previous Mortein products worked. Like all the other reviews this product is 100% useless. Very disappointed since trying to enjoy a Christmas lunch out doors. The flys appeared to enjoy the bath when in contact with the spray and happily flew away. The Mosquitos just kept flying around until slapped with hands. Hopefully the manufacturers will read the feedback and fix this problem. It might as well be a can of water.
