Inside the collection of bugs we can catch in Animal Crossing: New Horizons, flies are probably one of the least frequent, as long as we have our community clean. But there are ways to catch them, like They wanted to detail from Nintendo Life.
And we can easily capture one only at the cost of losing a little prestige of our people. The idea is that these insects always appear around the trash, so just leave some trash on the floor
Once they appear, it will be enough to approach them and catch them. A very simple method to add this insect to our collection. Have you already caught any flies in Animal Crossing: New Horizons?
