Chiming in to double confirm! Sundews/ Drosera/ "Death-by-lollipop-hugging" are super fun and cute and will go to war on insects. I've also had great luck with growing lowland and highland Nepenthes, tropical pitcher plants, indoors. Carnivorous plants are sometimes a little picky about temperature and humidity, especially the colder-climate ones that require dormancy periods, but there are some really rewarding and fairly forgiving ones.

Fixing my neighbor's trash can problem was what I needed to solve my fly infestation a couple summers ago, but my apartment bog ab-so-lutely racked up a ton of kills during the war.

Pro-tip: Carnivorous plants usually evolved in some nutrient-lean areas and can be pretty sensitive to the salts and minerals in tap water. A Total Dissolved Solids meter is cheap and helpful for double checking to make sure you aren't going to run into trouble. Some people don't have to worry about it, some do. I have a still for distilling water at home, lots of people rig up rain catchment systems, or buy reverse osmosis water at the store. There are options.
