Very effective 230

I live close to horses, and I flies in the house when it's hot to the point that it ruined the daily.
This box attracts flies very impressively.
By cons, it is essential to cover the already flies caught by drowning them by shaking the jar, because I am part of a week and the return I got hundreds .... or more! It is reproduced in the box ... I had to throw everything at once.
I left with water and fish waste in the water, the sun, sheltered from the wind.
I recommend this product!
