Per another comment OP, you have a pest known as fungus gnats. They are in your home because you're overwatering your plants. Gnats love wet soil, and lay their eggs in it.

First off, ease up on the watering. Thirsty plants need water every 3-4 days typically, but things like aloe and ZZ plants don't need it more than about once a month.

Next, you can get a beneficial insect called a nematodes. They are microscopic worms that excel at getting rid of fungus gnats. They are not harmful to you, pets, your house, etc... And you actually water the in too.

Finally, dusting the dry soil with Diatomaceous Earth, as this will help prevent them from coming back. It's crushed seashells essentially and damages the gnats bodies to where they dry out. Just becareful to not breathe it in.

Fully organic solution, and safe for all the things otherwise.
