Insect Question--- help!

[Cookiemonster]

Hello everyone,
I was just looking closely at my orchids today and found tiny black insects, like I really had to look to make sure they were moving and they were-- they seem to be eating the flower, I was curious as to why it seemed so be looking so sickly... I managed to blow it off the plant but there seems to be a few more, if anyone knows--any idea what this is??

And what can I buy as an insecticide to kill this insect and prevent future insect outbreaks... Someone mentioned making a mixture 1/2 of rubbing alcohol and 1/2 of 405? I dont know that scared me a bit, Im looking at Garden Safe Insecticide killer,
oh yes these are indoor plants, its somewhat warm, not too humid...

thanks everyone again
