5 tips to prevent a plant fly invasion

Preventing a plant fly problem is of course even better than solving one. To make sure your plants will remain fly free, there are some things you can do to tackle the potential problem at its roots – literally.

1. Check the soil of new plants

Often plant flies (fungus gnats) appear in your house via the soil of a new plant. Before you bring a new plant into the house, make sure the soil is free of larvae.

2. Measure the amount of water

Larvae develop themselves super-fast in wet soil. When watering the plants, make sure you don’t give them too much. This way the soil gets the chance to dry up after watering.

3. Place your plants in a drainage pot

By placing your plant in drainage pots, you make sure the soil will never get too wet – which makes it harder for larvae to develop themselves.

4. Remove dead plant remains in time

By removing dead plant remains in time, you will take away an important food source for the flies and larvae.

5. Repot the infected plant

Find out which plant is infected, isolate the plant and replace the soil. Only move the plant back in with the others when you are absolutely sure that the soil doesn’t contain larvae anymore.
