The first thing we did.. it's so polluted within a couple of days you'd think we had it out for months. Literally the only things they would be attracted to are the cat food dishes and the litter box. But I can't do much about that. It's coming from the garbage shed outside. It's an uphill battle
Various liquids in cups with cling wrap, taking out compost and garbage daily, sometimes twice, NO food left out ever, sanitizing kitchen daily, vacuuming and mopping regularly, bleach, vinegar, boiling water, spraying poison, vacuuming them, various forms of cinnamon, I'm sure I'm forgetting things
Our house looked like the house in Signs where the little girl left all the water glasses out on every surface lol I hate the smell of vinegar, but I hate fruitflies more lol your landlord suuucks
