[Retlaw]

Got a couple of these about 3 weeks ago, just used one and this is the result in 21 days 1000's of dead flies, once they get in they can't get out, the liquid at the bottom is supposed to emit a pheromone which attracts female flies, just flies, doesn't affect bee's.
Who would suspect that so many blue bottles would visit your backyard in so short a time, only had two of the dirty beggars come in the house since it was activated.
The makers reckon they can catch up to 20,000 fies in 12 weeks
