Ollie® pest control
Control fungus gnats with yellow sticky traps for houseplants
Easy guidance
Address fungus gnats on plants correctly
Sticky traps reduce adult insects, but larvae live in damp soil, making plant care part of the solution.
-
Identify them correctly
Fungus gnats are small dark flies that commonly emerge from damp potting soil and fly around plants.
-
Adjust watering
Where the plant tolerates it, let the top layer of soil dry between watering and avoid waterlogging.
-
Use sticky traps
Insert traps near the soil as directed. Their adhesive surface catches flying adults.
Frequently asked questions
Are fungus gnats the same as fruit flies?
No. Fungus gnats are usually found around potting soil, while fruit flies favour fermenting fruit, food waste or drink residue.
Do yellow sticky traps also treat larvae in the soil?
No. They mainly catch flying adults. Plant care that reduces favourable larval conditions is also important.
How long should sticky traps remain in place?
Follow the product directions and replace heavily covered or no longer sticky traps while continuing to monitor activity.
