I’ve got several small houseplants in my home office, and I really like having them around. I’m still pretty new to taking care of them altogether, though, and we’ve gotten dozens of tiny house gnats now. I’ve put up sticky traps and tried to use some pest control in the potted soil. But would a small venus fly trap be able to help here?

I’ve tried this and the answer is no. You really just need to get rid of whatever’s attracting the gnats.

Fungus gnats are generally the result of overwatering your plants. Let the soil surface dry out between waterings, and they’ll disappear.

As far as carnivorous plants go, I have had more success with butterworts. Sundews are also good. Venus flytraps are considered harder to grow in general and harder to keep alive indoors without manual feeding.

Can confirm sundews, specifically the commonly found Drosera capensis is very easy to care for and should be good at catching bugs as long as they land on the tentacles

Thanks for the info! I ordered a sundew and I’m very excited for it to arrive.

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.

No, not really. My VFT catches gnats but I don’t think it would effectively reduce them overall.

Put ground cinnamon on your soil. It kills the larvae.
