Make a fly trap that works? What bait to use?

On the other hand, I found that flies are attracted to heat so they detect infrared!

That's probably why when it's cold outside, they still try to get out!

The mosquito and the moths, him "see" the infrared, the fly, not sure at all.

I feel like they are just sensitive to air temperature, so they can follow convection movements. I surprised one flying towards the fridge door I had just opened. She made a sharp U-turn at the last moment as she tried to enter.

So they try to get outside when it's cold but they don't want to get into your fridge?

How's Orangina?

Maiiiiiiiiis no, you open the fridge: call for air, she looks stylish she comes in. You close the door in the face of this fly xwklghtexwq, the air comes out, she bars herself in the flow.

What I can say is that around August 20 we didn't move much from the house.
No fly, or one here and there....

Around September 1, in the kitchen, my wife tossed the lemon and nails.

A few days later, a few flies.

She put the lemon back, and the nails, and 2-3 days later, no more flies...just those who don't know, and come astray, and leave very quickly!
