Flipping: Best Way To Get Rid Of Roaches In A House

[Rashad Jones Jennings]

I am working on a flip and everything has been completed from the renovation to the photos to get ready to list it on the market. The only issue is the person I bought it from had roaches really really bad. Its been 3-4 months since the renovation was completed and they are still not eradicated. I currently have 2 companies going out treating the property (Orkin & Arrow). Thats not working fast enough, I don't have 3 more months of holding this property to wait. Any home remedies? Anybody had this same issue and solved it? I just can't put it on the market while they are not fully gone.
