Fungus gnat nematodes are a natural method to reduce tiny flies around indoor plant pots. These microscopic organisms, Steinernema feltiae, are watered into compost or soil where they actively search for and destroy fungus gnat larvae. This interrupts the breeding cycle and helps protect plant roots from damage.

Helps Reduce Fungus Gnat Flies In The Soil

Fungus gnats often appear in greenhouses, conservatories or houseplant containers. While adult flies don’t harm plants, the larvae live in compost and feed on roots and organic material, weakening plants over time. These nematodes are introduced to the soil where the larvae are most active, helping reduce their numbers before they mature.

Suitable For Indoor Use Around Plants, Pets And People

This product can be used safely around edible crops, pets, and children. Apply to pots growing herbs, fruit or vegetables indoors or outdoors during warmer months. There's no waiting period before harvesting after application, making it ideal for edible plant setups.

Easy Application To Compost Or Potting Soil

Mix the contents of the pack with water and apply evenly over moist compost. The nematodes move through the soil in search of larvae. One treatment covers up to 12m². For ongoing results, reapply regularly in warmer months or in spaces where fungus gnats tend to return.

Frequently Asked Questions for Fungus Gnat Nematodes

What are fungus gnat nematodes and how do they work?

Fungus gnat nematodes are microscopic beneficial organisms (Steinernema feltiae) that naturally target and kill fungus gnat larvae living in the soil of indoor and potted plants. They help stop tiny flying gnats by breaking the breeding cycle at the root level.

How do fungus gnats harm indoor plants?

Fungus gnat larvae feed on organic matter and plant roots in the soil, which can lead to weakened growth, yellowing leaves, and poor plant health — especially in seedlings or young plants.

Are fungus gnat nematodes safe for use around pets and children?

Yes, these nematodes are completely safe for use in homes with pets and children. They contain no chemicals and pose no harm to humans, animals, or beneficial insects.

Can I use fungus gnat nematodes on edible plants and herbs?

Absolutely. Fungus gnat nematodes can be used on potted herbs, fruit, and vegetables. There’s no need to delay harvesting after applying them.

When is the best time to apply nematodes for fungus gnat control?

Indoors, nematodes can be applied year-round. Outdoors, they’re best used between April and August when fungus gnats are most active. Reapply as needed in warm or humid conditions.

How do I apply fungus gnat nematodes to my plants?

Mix the nematodes with water and pour directly onto moist compost or soil. Focus on the top layer of the potting mix where larvae live and feed.

How much area does one pack of fungus gnat nematodes treat?

One pack treats up to 12 square metres, making it ideal for treating multiple indoor pots, planters, conservatories, or greenhouse trays.

Do I need to change my plant care routine after applying nematodes?

You can continue regular watering and care. However, reducing overwatering and improving drainage will enhance effectiveness and prevent future gnat problems.

What are the signs of a fungus gnat infestation in houseplants?

Look for small black flies hovering around the soil surface and signs of larvae in the top layer of moist soil. Damage to roots may cause wilting or stunted growth.

Can I combine fungus gnat nematodes with sticky traps?

Yes, yellow sticky traps are a great companion to nematodes. Traps catch adult gnats while nematodes target the larvae, offering complete control above and below the surface.

How often should I reapply fungus gnat nematodes?

Reapply every few weeks or as needed, especially in warm, humid indoor environments where gnats tend to thrive.

Easy to assemble, does the job, material is shiny nylon and shows creases, minor defects, sloppy
Size: 3 Panel 12FT W, Size: 3 Panel 12FT W
The Siebwin room divider is a good idea, and for the price, it mostly delivers on the intended functionality. I ordered the 12 foot, 3-panel version mainly to hide an unfinished basement storage area that had become an eyesore. It works well for that purpose and gives the space a cleaner appearance without spending the kind of money that more decorative dividers or custom partitions cost. If you need something temporary, portable, or mainly functional, this is a viable option. There are a few limitations that became obvious during setup and use. The first thing I noticed was that the weld quality on some of the metal poles is fairly sloppy. Once the cover is installed, you do not really see it, but up close, it does not look especially refined or professional. The blackout material also is not a matte canvas style fabric as I expected. It has more of a shiny nylon appearance, and the creases are fairly visible. Being that it’s more of a nylon, I’d be hesitant to try steaming it to remove the creases. However, the creases do not matter if you are using it in a basement, dorm, or shared room, but for photography, video work, or a professional office setting, the appearance could be disappointing. The fabric is thick enough, though. It blocks visibility well enough, but strong light behind it still shows through to some extent, nothing deal-breaking. Also, my fabric appeared to be slightly defective. The hook and loop strip on one of the bottom sections was off-center and couldn't be totally attached because it was lined up with one of the legs. I originally hoped to use this as a video backdrop, but I will probably end up replacing the fabric with a proper green screen or canvas material while continuing to use the frame itself. For now, it does a good job of covering my basement junk. Assembly was actually easier than I expected and took roughly 15 to 20 minutes. The longer vertical poles are tethered together similarly to tent poles, which made setup straightforward and fairly intuitive. The shorter horizontal pieces slide and snap together to the top and bottom of the vertical assembly. After each section is assembled, the divider panels connect together with metal plates and two knurled screws (at the top and bottom), so no tools are really required. A few screws were difficult to start because paint had gotten into the threads, but once they caught, they tightened down normally. The feet install with similar knurled fasteners and help keep the divider reasonably stable. One thing to watch for during setup is the fabric orientation. There is one arrow indicator in the middle of the fabric to indicate up. However, if you need another indicator, the smaller hook and loop strip goes on the bottom while the longer strip goes on top. I realized mine was upside down right before finishing and had to redo it. I wasn't difficult to redo, despite the defect in mine. The overall design is practical and easy to move around. I do like that the panels can fold and bend into different shapes depending on the space. The widened feet help stability, although when trying to stretch the fabric tight, I noticed the poles sometimes wanted to overlap slightly at the joints. Tightening everything helped somewhat, but it still happened occasionally. The divider feels adequate for normal indoor use, though I would not expect premium durability or luxury-level fit and finish at this price point. The entire device can also be easily disabled and stored in a tote if you need it completely out of the way. It comes with assembly instructions, but even if you didn’t have them, it’s easy to build without them (save a mistake or two). In terms of value, I think the Siebwin divider mostly matches its price. Around $100 gets you a large freestanding partition with decent usability and easy assembly, but there are compromises in materials, appearance, and refinement. The defects are also off-putting, but hopefully you won't have them. Higher-end room dividers can easily cost two or three times more, so some of the tradeoffs are expected. I also noticed cheaper alternatives online, but based on the quality here, I suspect those would probably have even more issues. For practical home use, temporary privacy, hiding storage areas, or separating shared spaces, this is a good option as long as expectations stay realistic.

Works well but takes up more space than expected
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
This room divider does the job for creating a little extra privacy and was easy enough to set up. The panels feel decent quality and the wider feet help keep it more stable than some cheaper screens I’ve tried. My only issue is that it takes up a bit more room than I expected, especially with the feet sticking out. It’s still portable and folds away nicely, but definitely measure your space first. Overall it works well for separating a room or blocking off an area temporarily. i wish it came in other colors

Nice divider, serves it's purpose well!
Size: 3 Panel 12FT W
This room divider worked out very well for what I needed. I wanted a simple way to create a little more privacy and separation in a larger room without doing anything permanent, and this divider was an easy solution. The panels provide good coverage, and the black color gives it a clean, modern appearance that blends in nicely with different décor styles. Assembly was fairly straightforward, and once set up, the wider feet helped keep the divider stable on the floor. I was especially happy with how flexible the panels are to arrange. You can keep it mostly straight, angle it around furniture, or create a more enclosed private space depending on the layout you need. The material allows light to filter through slightly while still offering a noticeable sense of privacy. I’ve used it for separating a workspace area, but it would also work well in bedrooms, apartments, dorms, studios, or shared living spaces. Another plus is that it can be folded and moved without too much effort when you want to change the setup. Overall, this divider delivers a good balance of functionality, portability, and appearance. It’s a practical option for anyone needing temporary room separation without installing permanent walls or curtains.

Perfect for Adding Privacy to a Piano Studio
Size: 2 Panel 8FT W, Size: 2 Panel 8FT W
I Ordered the 2 Panel version which is way too big for my needs... that's on me. So keep in mind that the picture shows a fabric made for two panels only being used on one and hence it is not pulled tight; it would pull tight and not be so wrinkly if it was set up properly as two panels. The metal pools that make up the panels seem to be well made, stable, and of good quality. They were very easy to put together and they stand up tall with plenty of height. The appearance of it with the fabric on it isn't as elegant as it could be, but it still looks good enough. The material is plenty solid, not allowing light through it, and thereby making a solid barrier. I am using it to block the view out the studio door when a student is sitting at the piano to avoid distractions from the hallway. It will allow a student to enter the studio with our distracting the student who is at the piano.

Room Divider That Gives Instant “This Is a Separate Space Now” Energy
Size: 3 Panel 12FT W
The Siebwin 3 Panel Folding Privacy Screen is surprisingly effective at changing the feel of a room without requiring construction, commitment, or somebody yelling about load bearing walls. The 12 foot width gives a substantial amount of coverage, making it useful for creating privacy, dividing open areas, blocking visual clutter, or setting up temporary sections within larger rooms. This saved us a ton of time and money in our new studio and enabled us to create a kitchen and office in one room. The wider feet make a huge difference because flimsy room dividers that collapse every time someone exhales too aggressively are deeply annoying. This one feels more stable and grounded once positioned. The folding design makes it easy to move around or adjust depending on the space, and it folds down relatively compactly when not in use. It is basically the introvert curtain wall of dreams. The material has a clean, neutral look that blends well into different room styles without screaming “temporary office cubicle panic.” It works well for apartments, studios, shared spaces, dressing areas, or simply hiding the mountain of chaos you swear you are going to organize tomorrow. Practical, portable, and refreshingly easy to use without turning setup into a three hour emotional event.
