Welcome to Just Answer and thanks for your question. You have hit the nail on the head. It is time to call in the experts for an evalation of what kind of infestation you have. It isn't likely to be bedbugs since you aren't being bitten as well as your husband. Professional exterminators are accustomed to working in environments where there is computer equipment. If there is any doubt, you can always unplug and cover the equipment if they are using any kind of spray.
We who spend our time answering questions have no contact with customer service (the people you would have cancelled the subscription with). We know nothing about the financial end of the company at all, except we don't get paid for our time until a customer accepts an aswer.
However, you didn't ask for guidance in selecting a company. If that is what you wanted, that is what you should have asked for. All you asked was if it was time to call in the experts.
The detector dog is a good idea. Be sure that anyone you allow into your home is BBB affiliated. Any of the major national companies (Terminix for just one example that comes to mind) are reputable. Just Answer cannot recommend any specific company. That is just our policy.
