We have tried literally everything.. fly paper, sticky tap, rotten fish smelling container thingys..Flu Kill spray in with the Glade fragrance aerosol pump thingy.. Irish Soap, Pennies in a bag of water 🤣 It was expensive and terrible. Than a friend told us about FLY PREDATORS https://spalding-labs.com Best pest decision ever. Also we stopped using shavings in our puppy pen. You can see me sprinkling around the pen which is all dirt now. The pups and shavings have killed the grass, so no not as cute. The shavings were breeding flies we believe and we’re super hard to clean too. Give Fly Predators a try and let us know what you think. Or if you have any other helpful tips or tricks. We get flies in monthly, 10k or 20k depending on the weather, literally lol. Not cheap but so worth it. We have alot of clients and customers over, who wants to be swarmed by flies, am I right 🙂 www.chrisandgina.com
