fore the ants you can spray with ant killer. fore the flies what i do is i have misters in my yard it sprays water and alovera oil flies do not like the alovera
good luck

Hmm, that is an interesting problem to have. My dogs have food and water outside for them as well and I have yet to see any flies hovering. Maybe the problem is you don’t change the food and water enough and clean the bowls, thus causing germs and most likely odor that flies are attracted to. So your best bet would to keep the dishes in a cool dry place outside and wash the bowls daily as well as give them new food and water daily. If that doesn’t help maybe there is something in the brand of food your dogs eat that flies just like, so you should then consider switching them to a new brand of food. Preferably something all natural.

There are bowl within bowls, where you put water in the outer ‘moat’ and ants cannot get in… As far as flies goes… Good luck…

Don’t know about that but for ants you can either use powder borax or plain table salt. Ants do not like either and when they take it back to their nest and digest it they explode.

keep it clean is all i can say…that’s what i deed
