and they are still there. Is there something I can capture besides calling an exterminator?
I would bomb again put insect traps all in the couch hold your place clean put mothballs aroud bed and couch as well no animals or they will return if you can't see them, and they don't bite,
how do you know that they are at hand...?
Anything you buy will not achieve rid of them.First hoover around all lounge ,they bury into the edges and tear the underneath and verbs in there as very well then you will have to bring a professional sprayer,believe me they will jump into your handbag and the next entity is your bed and they will be sleeping with you and eating your arms,I have to get professionals in 3 times.There is no alternative to achieve rid of them naturally but it does not affect people[the spray] If you are talking roughly bedbugs, I recommend that you place a ripe guava fruit under the bed or sofa where they lurk. Don't mind the smell. They don't resembling it too. The bugs will migrate from your place.
