I am bitten about once a week in the usual 3 bite pattern. Have had 3 companies arch my condo. Can find no eveidance of bed bugs, or spider nests. Suggestion?

Thank you for your question.
Some companies are more experienced with dealing with bed bugs than others. Ideally, you'd want a company with trained dogs to sniff out the begs - if they are there.
I'm not what you mean by the usual 3 bit pattern. Insect bites aren't used to ID insects because people react differently to them.
Bed bugs feed and move somewhere else to congregate, digest, molt and breed. This often happens off the bed. If that is the case, you might be able to trap them for a positive ID. They don't fly so if bed is moved away from the wall and the only way for the bed bugs to get onto the bed is the legs, you could use double-sided tape on the legs as a sticky trap.
Virginia Tech also has a number of publications on bed bugs which may be useful, including:
Bed Bug Biology and Behavior (https://pubs.ext.vt.edu/content/dam/pubs_ext_vt_edu/ENTO/ENTO-8/ENTO-8-PDF.pdf)
How to Identify a Bed Bug Infestation (https://pubs.ext.vt.edu/content/dam/pubs_ext_vt_edu/ENTO/ENTO-4P/Ento-4P_pdf.pdf)
Flea and mosquitoes are other potential biters. Unfortunately without sample of the bug, it's impossible to tell what it might be.
