This BestTrap 20-pack comes as yellow fly paper stickers designed to attract insects to the surface and trap them using a sticky adhesive, without relying on insecticides. These traps are sized at 6x8 inches per piece and are intended for pests such as fungus gnats, whiteflies, winged aphids, leafminers and similar small flying or weakly flying insects. They’re also dual-side and include twist ties, which makes it easier to hang them where insects are likely to pass—near pots, along plant rows, or close to where you’ve noticed activity. ## What you’ll notice in day-to-day use On paper, the biggest draw here is the combination of the yellow attractant colour and the adhesive that aims to stay effective over time. The listing says the adhesive is waterproof, resistant to UV rays and “never dries out”, which is exactly what you want if the trap is going to sit out on a windowsill, greenhouse bench, balcony rail, or somewhere bright. A practical way to use them: after you water your plants (when fungus gnats are often easiest to spot), hang or place a few sticky pieces at plant level. Then give it a quick check after a day or two. If the sticky surface is working as intended, you’ll see trapped insects building up, which also helps you judge where the problem is most active. That said, sticky traps are more of a monitoring-and-reduction tool than a total solution. If you’ve got an active infestation with eggs in the soil, you’ll likely need to tackle the root cause alongside using these. ## Key features that matter (and what to consider) Yellow colour attraction is the core idea. The traps are made from non-toxic and non-chemical highly effective adhesive yellow paper, and the instructions emphasise that they don’t harm plants—so they’re positioned as a plant-friendly approach. The adhesive is also described as not drying and long-lasting, plus being UV and water resistant. That makes them more believable for outdoor or bright indoor placements, where cheaper sticky sheets can lose performance sooner. One point to keep in mind: the listing doesn’t give a specific “coverage” as a strict rule, but it does recommend a usage density. If you don’t place enough traps (or if they’re too far from where insects are flying), you may find results feel slower than expected. ## Sizing and placement guidance (so you get results) The information provided includes a density guideline: 1 piece per 18.6 m², or 200 pieces per 1 acre for best performance. In real homes, you’ll probably adjust that to your space and plant count rather than measure square metres. In practice, the traps work best when they’re close to the insects’ flight path. For example, if you’re seeing whiteflies fluttering near leaves, hanging a trap at canopy height can make a difference compared with placing it on the floor. ## Who it’s for It suits you if you want a relatively straightforward, plant-friendly way to trap flying pests like whiteflies, fungus gnats, winged aphids and leafminers around indoor plants, or in outdoor growing areas. It can also make sense if you’re trying to manage without insecticides, or if you prefer a visible, “you can see it working” approach (you’ll know where insects are ending up). ## Who should skip it It might not be a great match if you’re expecting these to eliminate pests by themselves, especially if the insects are breeding in the soil (for instance, fungus gnats). Sticky traps can capture adults, but they don’t address eggs and larvae on their own. Also, if you’re the kind of buyer who needs precise pest identification from a product description, this one won’t do that. It’s a broad trapping solution rather than a diagnostic tool. ## Final verdict **Worth considering if** you want yellow sticky fly traps for regular use around plants, including a long-lasting adhesive feel (waterproof and UV resistant as claimed) and an easy hanging setup thanks to twist ties. **Not the best choice if** you need a one-step, guaranteed eradication of an infestation—sticky traps are better treated as part of a broader control approach. If you prioritise visibility and plant-friendly trapping, this 20-pack from BestTrap looks like a practical buy for day-to-day pest management. ## Mini FAQ ### Do these traps use insecticides?
