Purchase Criteria
areas of application
Yellow boards or stickers can be used both indoors and outdoors. They are mainly used to combat fungus gnats on indoor plants, in conservatories, greenhouses and potted plants on the balcony or terrace, but can also help to contain annoying insect pests in orchards and vegetable gardens. The disadvantage here, however, is that not only pests get caught on the sticky traps, but also useful insects such as bees, bumblebees and Co. You should therefore think carefully about hanging up yellow boards outdoors to see whether there isn't a better method of pest control.
size
You choose the size of the yellow panel according to how big the plant to be protected is and how severe the pest infestation is. A yellow board in half DIN A5 format (A6, 10.5 x 14.8 centimeters) is sufficient for smaller indoor and potted plants, while larger or very badly infested plants require a correspondingly larger format. If you want to hang the panels in fruit trees or similar, then you should choose DIN A4. Some yellow stickers intended for indoor plants also have special shapes that are intended to make them more decorative.
adhesive surface
Of course, a yellow sticker should have the largest possible adhesive surface, because the more insects will get stuck on it. Boards that stick on both sides instead of just one side are particularly effective. These should be installed free-standing or hanging.
Adhesive and other ingredients
Yellow stickers usually consist of a piece of yellow cardboard coated with a special glue. Other ingredients such as attractants or insecticides are neither necessary nor useful, since the insects are attracted solely by the color of the panels and then stick to the sticky surface. However, the adhesive differs in its composition and mode of action depending on the manufacturer and product. The different adhesives stick differently and also react differently to factors such as strong sunlight (boards could dry out) or water (e.g. from watering).
mounting options
There are basically two ways of attaching yellow stickers: You can put them directly into the potting soil or you can hang them in the plant. For both variants you need fastening material, for example metal or wooden rods, clamps or wires. Some yellow boards come with these materials so all you have to do is assemble and attach them. With other offers, however, you are responsible for procuring suitable fastening material separately. However, wooden or plant stakes, as well as simple wire, are available at any hardware store.
youtubefrequently asked Questions
What are yellow stickers and what are they made of?
Yellow stickers are a very simple way of controlling pests on plants, which does not require any insecticides or other toxins. In principle, the panels consist of a piece of cardboard (or another material, which is coated with glue and placed in the immediate vicinity of the plant. It is a trap in which the distinctive yellow color does not attract the insects - the then get stuck on the adhesive surface and can no longer free themselves.
Are yellow stickers poisonous?
No, yellow panels do not contain any toxins and are therefore completely harmless in this respect. Nevertheless, you should keep curious roommates such as children and pets away from the stickers, as the adhesives used are very sticky and difficult to remove from clothing or hair. Should this be necessary, it is best to rub off the adhesive stains with a little cooking oil.
Against which pests can yellow stickers be used?
Yellow panels work very well against fungus gnats, whose eggs are often found in potting soil or potting soil that you have bought. But the sticker can also be used against fruit flies, winged aphids, whiteflies and other pests that suck on plants.
How effective are yellow stickers really?
In fact, yellow stickers are just a pest trap, as these panels can contain a very strong pest infestation, but cannot eliminate the cause. For example, only adult animals are caught, while eggs and larvae remain unmolested. Therefore, you should only use yellow boards as a preventive measure or in the case of a light infestation; further measures are necessary in the case of a severe infestation. In the case of fungus gnats, for example, you should repot the plant in question in fresh substrate or use nematodes.
Can yellow stickers be used on all plants?
Since yellow stickers do not contain any toxic substances, you can use them for all ornamental and crop plants without hesitation. Just make sure that no leaves or other plant parts get caught on the adhesive surface.
Which well-known manufacturers can you buy yellow stickers from?
There are yellow stickers from many well-known and unknown manufacturers. You can't go wrong with branded products from manufacturers such as Neudorff, Compo, Aeroxon, Substral or Nexa Lotte.
What are the disadvantages of yellow stickers?
Unfortunately, yellow panels also have the disadvantage of not only attracting and killing unwanted insect pests, but also beneficial species such as bees, bumblebees, hoverflies, lacewings, and others. It has also been reported that one or the other songbird had already gotten caught in these traps and could no longer free themselves.
