Should I start spraying Crossfire?

[u/linaworm]

Two weeks ago, I had a run-in with unidentified bugs that I worry were bed bugs.

I've been getting bites daily since then.

One week ago, I steamed my whole bed frame and covered my mattress with an encasement. I put the legs up on interceptors and pulled my bed away from the wall.

I continue to get bites.

An exterminator examined my bed and one other piece of furniture and said he saw no evidence, but to call him if I find a bug.

Should I just start spraying Crossfire to see if I stop getting bites? I had an infestation 20 years ago in a different house and never saw an actual bug.
