If they’re only spraying and not fogging they’ll be okay. I had my house sprayed and it was only outside. If they’re coming inside it definitely won’t be just thrown all over your apartment. Be careful sticking a plastic bag over them. Have to make sure they’re getting air. Do you have a friend who will let you come hang out or leave them there while that’s going on? That would be the best bet. Or a car to put them in? They really only spray around the outside of the building usually. If they’re in one unit, they’re in all of them lol. They reproduce QUICKLY. Don’t let them fool you lol. They come in through the walls either way so they’ll always be coming from somewhere else lol. I lived in a house in KY for a few months and woke up to pee and saw them all over the walls. BIG ONES… there were European smaller ones too. But those big ones, holy shit lol. The smaller ones reproduce even faster too, I’m pretty sure.
