Bed Bug rated products

It's been 3 weeks since our heat & pesticide treatment for Bed Bugs & by all accounts we are in the clear! So thankful to God & the Universe for working through friends, family & even some strangers to raise the money needed for the treatment. Still feeling the high need to purchase BB rated products for our 2 beds. These encasements will be almost $300 for a queen & cali king matress & box spring. Also still need entire flooring in our condo cleaned post treatment & our living room, upholstered furniture still needs to be high heat steam cleaned to help clean up from the bugs. Trusting in God & The Universe that as the money presents itself, we will get all of this done & there will not be any issues with re-infestation. Thank you all!
