A strong yellow sticky trap for gnats offers a bright, adhesive surface suited to the number of plants and the way you plan to place it. For houseplant owners, the best fit is usually a trap that targets fungus gnats and can sit near the potting soil; gardeners may also want larger sheets, tie-on placement, or weather-resistant construction. This roundup compares 10 options, from 20 large 6-by-8-inch cards to kits with as many as 100 pieces.
Several are double-sided, and some include ties or stands, while others use decorative shapes designed for pots. These traps catch flying insects rather than addressing every source of an infestation, so consider placement and replacement needs alongside pack size.
The rankings prioritize explicit fungus-gnat use, useful dimensions, and included placement components.
Gideal 20-Pack Traps is the best overall choice because its listing explicitly names fungus gnats and supplies 20 dual-sided 6-by-8-inch traps, 20 twist ties, and two stands. That combination suits houseplants as well as outdoor plants, and the product is also listed for gardens, greenhouses, and nurseries. For someone who wants a substantial supply of smaller, decorative plant traps, other options in this list may fit better, but Gideal offers the clearest combination of large trap format and ready-to-use placement accessories.

Each trap has adhesive on both sides, providing two capture surfaces for monitoring fungus gnats, fruit flies, whiteflies, aphids, and other small flying plant insects. The 60-piece assortment supports placement in multiple pots or growing areas, and the four designs help vary the look across visible plants. Briteen’s supplied details identify indoor and outdoor plant use, but do not describe mounting accessories or an installation method, so placement planning may depend on the location.

View on AmazonWhy it ranks #10: The title names fungus gnats and the listing describes 100 double-sided, waterproof traps, but it provides fewer specific plant-placement details than higher-ranked choices.
Boromine supplies 100 double-sided yellow sticky sheets with a waterproof coating, giving buyers a large stock for repeated placement around plants or damp areas. The listing specifically identifies kitchens and rainy gardens, so this set suits shoppers who want traps whose adhesive remains intact when exposed to water.
The double-sided surface catches insects approaching from either face, while the thickened adhesive increases the available trapping area for plant protection. Boromine’s waterproof coating is stated to keep the adhesive intact after water contact, supporting use in damp kitchens and rainy gardens. With 100 sheets included, you can distribute traps across multiple plants or locations and replace them as needed, rather than limiting placement to a small number of pots.
- Includes 100 yellow sticky traps for broad placement.
- Double-sided adhesive offers capture surfaces on both faces.
- Waterproof coating is stated to maintain adhesive after water contact.
- Listing describes the adhesive as odorless and non-toxic.

View on AmazonWhy a sticky card may not stop the gnat problem
A yellow sticky card catches flying insects, but the product listings describe traps for flying pests rather than a complete treatment for every stage of a gnat infestation. That distinction matters: a card can collect adults while the source of recurring gnats remains around a plant. These products are intended for use near plants, and Cleanuper specifically recommends placing cards at soil level near drainage holes for faster results.
Treat that as placement guidance, not proof that one trap location fits every pot. A common failure mode is relying on a single card far from the affected plant, then assuming the trap has failed when it has little opportunity to catch insects.
Use enough cards to cover the plants where gnats are appearing, and monitor what they catch. The listings do not establish a replacement schedule or claim that sticky traps alone eliminate an infestation, so check the adhesive and follow the product’s instructions rather than assuming a fixed service life.
Large sheets and shaped cards solve different placement problems
Large 6-by-8-inch sheets offer adaptable coverage, while small decorative cards are easier to place visibly in individual pots. Gideal, Garutom, Kensizer, Faicuk, and Qualirey list large sheets or cards, and several can be cut or are described as cuttable. That flexibility can help when a pot needs a smaller trap, but cutting an adhesive sheet can make handling and placement messier.
Decorative formats such as Cleanuper’s sunflower and butterfly cards or Kikalife’s fruit shapes are designed to sit in plant displays, but the supplied data does not give their adhesive area for comparison with the larger sheets. Do not assume that a higher piece count means more total sticky surface: the 100-piece kits and 20 large-sheet kits use different formats.
Choose by where each trap must go, whether it can hang or stand, and the dimensions or placement accessories actually listed.
How to Choose Yellow Gnat Traps
Trap size and format
Look for a format that fits the distance between foliage and the pot, rather than choosing by piece count alone. Several products, including Gideal, Faicuk, Garutom, Kensizer, and Qualirey, list 6-by-8-inch sheets or cards, and Faicuk and Kensizer say their traps can be cut. Smaller-format alternatives include Cleanuper’s sunflower and butterfly cards and Kikalife’s fruit shapes, with Kikalife listing dimensions of 3.3 by 5.3 inches.
Larger, cuttable sheets suit gardeners who need to adapt a trap to different plants or positions. Smaller shaped traps may suit individual houseplant pots where appearance and compact placement matter.
Compare listed dimensions carefully: a pack with more pieces does not necessarily provide more adhesive area per trap or overall.
Pack quantity and included placement pieces
Choose a supply size that matches how many plants you need to monitor and whether you need help mounting the cards. Pack counts range from Gideal’s 20 large traps to 100-piece offerings from Qualirey and Boromine; other options include 30, 36, 40, 58, and 60 pieces. Gideal includes 20 twist ties and two stands, Garutom lists 20 ties and two holders, and Qualirey includes 100 ties.
Those accessories are useful when hanging or positioning traps is part of your setup. A smaller kit may suit a few houseplants, while a larger count can cover more pots or allow more monitoring points.
Check what comes in the package rather than assuming every trap includes ties or a stand.
Indoor and outdoor conditions
Check whether the listing describes use in the conditions where your plants are kept. Many products state indoor and outdoor use, while Gideal also names balconies, orchards, greenhouses, and nurseries. Garutom and Kensizer describe resistance to rain, and Boromine lists a waterproof coating; these details may matter for exposed outdoor placement.
Faicuk identifies gardens, farms, greenhouses, outdoor plants, and houseplants as uses. For indoor pots, a compact shape or included stand may be more relevant than weather claims.
For exposed gardens, the listings that specifically mention waterproofing or rain resistance provide more relevant information than a generic indoor-and-outdoor label. The provided data does not give comparative test results or exact weather-life durations, so treat these descriptions as product claims rather than a guarantee of performance in every setting.
Which Yellow Sticky Trap Should You Choose?
For most plant owners seeking a clearly specified gnat trap with flexible placement, choose Gideal 20-Pack Traps: it combines 20 large dual-sided cards with ties and stands. If you want cuttable sheets for a range of plant sizes, Faicuk 30-Pack Traps is a strong alternative; for outdoor placement where rain and heat resistance are specifically described, consider Garutom 20-Pack Traps. Choose Qualirey 100-Piece Traps when you need many large cards and matching ties, or Cleanuper 58-Pack Traps when decorative shapes suit your pots.
Kikalife 40-Pack Traps offers fruit-shaped cards with soil insertion or hanging. For a smaller number of plants, Kensizer 20-Pack Traps or Mosqueda 36-Pack Traps may fit.
Boromine 100-Pack Traps has a high piece count, but fewer placement details are provided.
Frequently Asked Questions
Where should I place yellow sticky traps to catch fungus gnats?
Place traps near affected plants, where adult gnats are likely to encounter them. Depending on the trap design, you can position cards in the soil or hang them near foliage. Gideal includes ties and stands for flexible placement; follow each product’s instructions for its intended setup.
How often should I replace a yellow sticky trap?
Replace a trap when its sticky surface is covered with insects, dusty, or no longer catching gnats effectively. Check it regularly, since the right timing depends on how quickly it fills and the conditions around your plants. Follow the product instructions for any specific replacement guidance.
Can sticky traps eliminate fungus gnats without treating potting soil?
No. Sticky traps catch adult flying gnats, but they do not treat the potting soil where immature stages may be present. They can help monitor and reduce adults, but traps alone may not resolve an ongoing infestation.
Consider addressing the soil as well, following appropriate plant-care guidance.
Do yellow sticky traps need to be dual-sided?
Not necessarily. Dual-sided traps offer sticky surfaces on both sides, while other formats may still suit your plants and placement needs. Check the listing for the design and accessories provided.
Several options here are described as dual-sided, including Gideal, Garutom, and Faicuk.
Which trap format suits plants of different sizes?
Cuttable sheets can be adapted to a range of plant sizes, making Faicuk a strong option when you want that flexibility. For larger cards with placement accessories, Gideal includes ties and stands. Decorative shapes or fruit-shaped cards may suit pots where appearance is also a consideration.
Final Words
For most plant owners, Gideal 20-Pack Traps is the clearest all-around choice: it specifies fungus gnats, large dual-sided cards, ties, and stands for flexible placement. Choose Faicuk if cuttable sheets better suit different plant sizes, or Garutom for the listing’s stated rain and heat resistance outdoors. Qualirey offers many large cards with ties; decorative shapes and smaller packs provide alternatives for other preferences.
