The pesky little black or grey flies darting around your indoor plants are fungus gnats! While the flying adults are just plain annoying, it’s the larvae which live in the potting mix that can be doing some serious harm to your plants.
The adult flies lay their eggs into the potting mix and the teenie tiny, larvae hatch out and feed on organic matter including plant roots and soft tender stems. This can cause wilting and slow the growth rate of your plants right down.
But there are 3 simple ways to get rid your fungus gnat problems!
Number 1 – DO NOT overwater your plants. Fungus gnats love wet potting mix and outbreaks most often occur when the soil isn’t allowed to dry out between waterings. The eggs and larvae need continuous moisture to survive, so allowing the soil to dry out before you wanter can help break the lifecycle.
Number 2 – Kill the larvae in the potting mix using a soil drench of eco-neem. This is really easy to do – simply mix up the right dilution in large bucket. Then take each of your plants and allow them to soak in the mix until the air bubbles have stopped. Let them drain outside in the shade, before bringing them back inside.
You’ll need to repeat this soil drench in 7 days because the flying adults can live for a week or more.
Number 3 – Do NOT allow water to pool around the roots of your plants. So tip out excess water that may gather in cover pots or saucers after watering. Leaving it will just encourage algae to grow, which the fungus gnats will just feed on!
So don’t let fungus gnats invade your indoor plant jungle and remember….there is anyways room for one more plant!
