Yellow Sticky Traps for Fungus Gnats - Fungus Gnats - Double-Sided

These traps are made from a rigid plastic base coated with non-toxic entomological glue on both sides.

This special adhesive remains effective over time without drying out, even in humid environments near the substrate. It contains no insecticides or harmful substances.

The bright yellow color is obtained by pigmenting the support, calibrated to match the light spectrum that naturally attracts dipterans such as fungus gnats.

You can use them with confidence near your edible plants or in a home with children and pets.

Carefully remove the protective film from both sticky sides. Plant the trap vertically in the substrate, near the base of your plant.

This position is strategic because adult fungus gnats generally stay close to the substrate where they lay their eggs. By placing the trap at this level, you intercept the females before they lay their eggs.

For a pot less than 15 cm in diameter, one trap is sufficient. For larger pots, place two or three traps around the plant. Check them weekly and replace them as soon as they are covered with insects.

Avoid touching the sticky surface with your fingers, as this will reduce its effectiveness.

The flying adults are primarily a visual nuisance, but it's their larvae that pose the problem. These small white worms live in the substrate and feed on decaying organic matter.

In cases of severe infestation, the larvae also attack young roots and rootlets, weakening your plants. Symptoms include stunted growth, yellowing foliage, and a general lack of vigor.

Young plants, cuttings and seedlings are particularly vulnerable because their root system is still fragile.

Acting quickly with traps makes it possible to break the reproductive cycle by capturing the adults before they lay eggs.

Several factors can explain a low capture rate. If your traps remain empty, it may simply mean that the infestation is light, which is good news.

First, check that you have removed the protective film from both sides. Also, make sure that the traps are positioned at substrate level and not high up in the foliage.

Light plays an important role: in a very dark place, the attraction of yellow light is less effective. Move your plants closer to a light source if possible.

If you see flies but they are avoiding the traps, the problem may be caused by insects other than fungus gnats. Observe their size and behavior to identify the species.

The yellow traps capture the flying adults, but for total eradication, it is also necessary to eliminate the larvae hidden in the substrate.

THESteinernema feltiae nematodesThey are the ideal complement. These beneficial microorganisms parasitize and kill fungus gnat larvae without harming your plants. The combination of traps and nematodes attacks the problem on two fronts.

As for prevention, space out your waterings to avoid a constantly damp substrate which encourages egg-laying.sprayerIt allows the foliage to be moistened without soaking the substrate.

Add a thin layer of sand or perlite on the surface to discourage females from laying eggs.

Yellow traps offer a passive, mechanical approach, unlike insecticides which act chemically. They allow you to monitor the level of infestation while reducing the adult population.

Against nematodes that target underground larvae, traps complement the action by capturing flying adults. The two methods are complementary rather than competitive.

Compared to repellent sprays, traps have the advantage of being odorless and operating 24/7 without intervention. They don't stress your plants and leave no residue on the foliage.

The main advantage is its simplicity: no preparation, no measuring required, just plant and let it do its work. Ideal if you're new to pest control.
