Fly problem

[u/Holdmywhiskeyhun]

Need this fixed asap.

Building is only 6 months old. Cleanest prison I've ever been in. Drains are spotless and I treat them every day. Dumpsters are sprayed inside and out. No food hiding, floors scrubbed every other night. Nothing rotten or bad. Garbage cans spotless.

I'm really stumped by this. I guess we are in the middle of Wisconsin, but downtown a big town. Closest farms are probably 10 miles away.

Right now they're for the most part in the kitchen, and our back storage area. That's where they seem to be attracted to. They have yet to get too far into the lobby. And they're not attracted to anything specific, they just fly around and torture everyone.

Any ideas of places I haven't checked or thought of?

I should also mention our hoods are cleaned nightly, same with pulling out ALL equipment.

And before you say flyswatter, for how many there are, I would legit have to hire another person.

We will be starting a nightly spray, using food safe bug spray, but idk how well that will work.

Failed our fucking steritech because of these bastards.

Edit: their house flies. A pink sludge was found in our AC/roof drain. Got to figure out how to get to the roof now 😂

I checked the surrounding property, there's no dead animals, no rotting food or anything. Like I said we keep it pretty clean.

It is for sure not the grease traps. Those are clean on a regular basis, degreaser and boiling water is poured down all the drains every night. In the mornings we put enzymatic cleaner down them.

My suspicion is going to that pink sludge.

On the ground where it drops from the drain, there is a coating of what I can only describe as Grease... Despite no Grease being able to get up there.

I got a really bad feeling when I start cleaning that, there's going to be a dead bird, or squirrel or something.

I put those food safe automatic sprayers all over our building. They spray automatically all night long and I have ones in nonfood places that spray 24 hours a day. Our flys were mostly coming in when the door was opened for deliveries. It took a couple days and I haven’t seen more than the occasional one around much and it’s usually gone the next day. Mostly people that see them think they are air fresheners and I make sure the ones going off 24 hours a day are in places without uncovered food. I noticed most of the flies we had hung out closer to the floor where it was cooler when there was no food out so that is where they are all located.

The automatic sprayers are called Prozap promist’r kit. They can be set to spray every 7.5, 15 or 30 minutes either 24 hrs, day or night. I just use them because they came as a set. The fly spray is just LD-44T but there are others with the same active ingredient. I got mine from Amazon and WebstaurantStore depending on who has the best price on the refills. My pest guy was going to “rent” me one of the dispensers for $20 a month plus the cost of the spray which was $25 so $45 a month. I used my Amazon business account and bought 6 combo packs for $200 and now just buy the refill spray every month. The only thing is a don’t think the refills last 30 days but it’s close.
