PLEASE HELP me identify this insect. I'm desperate!!! (fleas, paint, glue)

[TumbleBug]

Goodness knows what this is - I wasn't so worried about it when we only had a few.
My pets had fleas so I flea bombed my whole house - did a great job with the fleas but I still have these horrid insects flying around.

Since flea bombing I have covered every square inch with a 6 month surface spray - these insects just dance around on it - it doesn't bother them in the slightest.

I'm over it - I need HELP.

First step is identification. Please help!

They are 2mm long tiny little things. They do not bite at all, and don't seem to be attracted to food. But they do like water and often can be found sitting on the pet's water bowl lip.
I made a apple cider vinegar trap but they weren't interested.
I don't know where they are coming from - but they leave a mess on the walls which may either be poo or eggs... I have no idea which, but I clean them off all the time and they seem too small for eggs??

Ah, I'm lost.
Here are the pics.

It kind of looks like a large fly but the last photo looks like a bug we have had in our house. Its some sort of beetle. The first time I found one was when I removed some wall shelves to paint. It just fell off the shelf. I freaked wondering if it had been buried in the wood of the shelf. Then a few days later I saw one buzzing around the chandelier. Then I found a few more. I looked it up online and if it is correct, it is a harmless household beetle. I never saw one before until now. It has been weeks and I have no seen one since. Of course now that I say that, I will find one tomorrow.

The common house fly.

OP, just go to the hardware store and buy yourself some fly paper. It will attract and trap the pests in short order.

Thanks for your responses!

It's neither a beetle nor the common house fly. It's only 2mm.
Very small and is not killed by ordinary fly poisons + it is NOT attracted to food.

I'm hoping to avoid fly paper as it is so ugly. If I can't identify the insects I'll have to catch some and see a professional - I'd prefer to sort it out myself as I don't have hundreds of $$ to waste.

If you do catch one, take it to the County Extension office. They should be able to ID it and tell you want you can do to get rid of them (for free).

They almost look like fruit flies. If I get fruit flies I've found that ordinary aerosol hairspray works well.

Looks like sewer fly-

Try a Raid fumigator - NOt a fogger. They are very different. They are pricy, but seem to kill pretty much everything. We use lisghtly more than the recommended coverage just be be certain. We have yet to see anything survive fumigation except some kind of moth.
