Bed Bugs

Danielle
I just learned that my friend had bed bugs . She said she got rid of them but when I was putting up a curtain I happened to see a bug inside the wall in a crack . It looks like a adult bed bug . I sprayed it with bed bug spray . I happened to flip her bed like 3 minutes ago and under the mattress I seen a shit ton of bed bugs in one spot and eggs . I Hauled Ass ! 😏😏 . What do I need to give her ?? She lives in apartments .
