Cockroaches. It was bad. They were everywhere. You couldn’t open a door without them falling from the cracks in the doorframe on your face.
Boric acid is what helped as recommended by reddit. We used to clean, and spray with Pyrethrins before that but that only kills the visible ones. Most of the roaches are in their holes and you’ll never reach them like that.
What’s great about boric acid is that it kills slowly meaning they can infect each other before they die in a chain reaction. They infect even the hidden ones when they go groom each other.
So clean the area, dry it, then just spread the powder where they usually hang out. It’ll take a week to notice any effects. Apply again if area gets wet.
Another great thing is unless you ingest a huge amount or inhale it in your lungs, boric acid is mostly safe for humans. Unlike the sprays which always gave us symptoms.
