🪰 What are fungus gnats and are they harmful?

Fungus gnats are small flying insects that live and breed in moist soil. While adults are mostly a nuisance, their larvae can damage delicate roots and slow plant growth.

💧 Why do I keep getting fungus gnats?

They thrive in consistently moist soil with organic matter. Overwatering and poor drainage are the most common causes.

⚡ Does hydrogen peroxide really work?

Yes — when diluted correctly (1:4 with water), it kills larvae in the soil and helps break the lifecycle without harming healthy roots.

🔁 How many treatments do I need?

Most infestations clear within 1–2 treatments spaced 5–7 days apart. Severe cases may need a third.

⏳ How long does it take to get rid of them completely?

Typically 10–14 days, depending on consistency and how well the lifecycle is interrupted.

🌞 Where do fungus gnats go during the day?

They hide in the topsoil, under pot rims, or nearby surfaces, and become more active in the evening, especially around light sources.

💨 Does using a fan help?

Yes — fungus gnats are weak flyers. Airflow disrupts their movement, reduces humidity, and discourages egg-laying.

🪴 What can I add to soil to prevent them from coming back?

Use a well-draining mix and top with perlite, LECA, or coarse sand. A light dusting of cinnamon can help reduce fungal growth.

🧂 Can I use diatomaceous earth (DE)?

Yes — apply a thin dry layer on the soil surface. It helps kill larvae but only works when dry.

🌿 Do I need BTI (Mosquito Bits)?

Not always. Many infestations can be cleared without it, but BTI is an excellent long-term prevention if gnats persist or recur.

🪤 Should I keep using sticky traps?

Yes — they act as an early warning system and help monitor any returning gnats.
