Thank God I don’t have to replace any of my furniture yet or I wouldn’t know what I would do, because my income is limited also…if the landlords were more cooperative in dealing with this the problem of bed bugs wouldn’t be a problem….I read something about bed frame posts to put on each foot of the bed and it keeps the bugs from entering your bed…also to use at least 5lbs. of Diatomaceous earth or perma guard, it’s a safe powder substance you spread all over your house, on rugs, cracks foundations etc. and this seems to kill them you leave it down for a few days..the cost is minimal as low as $10.00- $15.00. Well worth the investment, you can purchase it online, EBay or your local feed and supply store.
I found something that works. Diatomaceous earth or perma guard. Buy a big bag. About a good 5 pounds and put it around the whole house yard in your bed in every crack the carpet. I mean all over and give it a couple days. They will be gone. I live in an apt I ha e a cat n dog. It isn’t harmful to pets or humans its 100% safe to use around kids and best of all no bed bugs no ants no roaches. I paid about $10 on ebay. Good luck and I’m telling u this worked for me.
