Not when they play around in dog sh*t then walk around the rim of my beer glass.I looked it up and apparently flies are quite a useful creature.
Can cats catch flies like some dogs can? One of my dogs in the past could catch them and eat them with ease,though the mutt i have now scarpers when they land on him,sending him hiding behind the settee!
I've had one of these for years - cheap, deadly accurate and zero running costs:
How about putting some fly food in the microwave and when they go in for it,slam the door shut,put the thing on and watch them pop?
