Last night, at around 3AM, I got two bites on my left hand and got up to inspect my covers with a flashlight to find a bedbug scurrying away, which I killed. 3 minutes later, I found one on the floor next to my matress. It ran from me and hid in a crack in the floor where I doused it in bleach.
3 weeks ago I borrowed a bag from my grandma's room and found around half a dozen bed bugs on it, to my horror. My house is clearly infested and, between me and my two grandmothers, I'm the only one showing bites.
I'm 21 and have no money for an exterminator. Neither does either grandma I live with, nor are they willing to acknowledge the infestation with anything more than ignorance and dissmissiveness. We live in a private house, so there is no landlord to complain to. I feel so helpless and I'm scared of spreading these things to my friend's or co-workers. Is there anything else I can do?
