You can see NoSeeums. If you are spraying randomly for something you cannot see, then it is very likely not insect related. I used to have a lot of information on website about this topic, but I got so many emails and questions that I took it down.
Here are the simple facts -
1. If you think something is biting you, then find out if other people in the same building are getting bitten too. If not, this is a personal issue. Many times it is dermatogical or prescription medication induced. There are many contraindications between prescription meds that can lead to what is called "formication". This is a real feeling of bugs crawling on you when none are physically present.
2. The only possibility of anything small enough to be so difficult to not be seen are either mites or chiggars. Chiggars are immature mites. In almost all cases mites (and only certain species) are the result of birds, animals, etc that live and breed in the building. You can easily use glue boards such as the Catchmaster 72MB placed along walls and other areas to capture them so they can be identified.
3. I don't recommend spraying anything indoor unless you have a verifiable insect and a targeted treatment approach. Randomly spraying or fogging indoors for something you can't see usually won't work, is expensive, and can lead to other issues.
4. If anything is biting you, there is usually a bite mark, etc that pops up. No bite? Usually no mite either...
Other than this I can't give you any specific advice. I recommend to figure out what the source is and only then - attempt anything. In the vast majority of cases like this, I have found that it was never an insect in the first place.
