Need help!!!!

So our disgusting neighbors decided to start remodeling their house and guess what.. we got their infuckingfestation of roaches. It literally went from zero to one hundred real quick. I don't know what to do! Our landlord has gotten us tempo spray to use and we've used raid contact kill spray and gotten little house type things that have some sort of bait in them that's supposed to kill them. But it just seems it isn't getting better! Neither us nor our landlord can afford an exterminator. She's trying to the best of her abilities to help us get rid of them. But I cannot live like this anymore! Moving really isn't an option just because I know they'll go with! We can't afford to trash everything and start from nothing with 3 kids. Our landlord has put in a call to our police dept to inspect the neighbors home to try and get in condemned so no more work can be done. Hell even the daycare across from us have seen them since they started remodeling. What else can we get to knock these suckers out as quickly as possible that's actually affordable!?!
