insect
After removing kitchen cabinets we found these dead insects underneath? What are they?
There flooring in my kitchen isn’t completely covered. For example kitchen cabinets have no flooring underneath them. I notice they exist around these areas perhaps at the edge of the vinyl. Why so?
Your guess of mold is correct. The moisture that was or is still present does attract termites also. Something worth checking into, why there is excess moisture enough to harbor mold
They are some kind midge flies (chironomids (Chironomidae))... obviously a biting kind of midge fly. A species specific identification would require a much better image, or preferably- a sample of the actual insects.
I see that you live in India... that makes identification more difficult because entomology is not a thoroughly studied science there.
Generally speaking, midge flies are controlled in the larval state (before they become adult flies). They are a lot like mosquitoes; they lay eggs in stagnant water (sewage, ponds, and drains are common). The larvae are commonly called redworms.
Eliminating the (stagnant water) source of the midge flies would be the most effective control, of course. Otherwise, a natural control method (recommended) would be Bacillus thuringiensis subspecies israelensis which can be found in many box-stores... look for "mosquito dunks".

Hard to tell from that dark grainy picture, but blowing it up, they might be dead "pill bugs", also called "roly-poley" bug, "doodle bugs" "wood louse", etc. etc. If so, they are harmless, don't spread diseases, don't destroy anything and are about as benign as you can get. They hide in dark moist places and eat decaying plant matter. So likely someone had garbage rotting under the cabinets at one time and it attracted them, then once it was cleaned out, they died of starvation. To be sure you can take a dead one down to a nursery and see if anyone there can tell you.
