Insecticide For Houseplants Gnats

Despite the fact Houseplants are some of the most common plants in homes, there is still a large amount of confusion concerning both their care requirements, and the supplies needed to make certain they remain healthy. One such confusing requirement that seems almost universal concerns the need to properly protect your houseplant soil from any kind of pest or infestation. This can prove challenging when your plants are kept in areas which permit easy access by insects you want to avoid at all costs (such as bathrooms or other locations with limited ventilation) and when you want to ensure you provide maximum protection for those who are unable to take preventative steps such as pesticides, or those who cannot ingest pesticides because of age, allergies, or other reasons.

What parts of the Houseplants do Bugs attack?

Depending on the type of bug, they attack different parts of the plant.

Some crawl and feed on leaves, some live in the houseplant soil, some flies around while some just stick to the plant like a fungi. Regardless of which type of bugs have attacked your plants. It’s of utmost importance to act quickly and get rid of them.

What are the Methods to get rid of Bugs in Houseplants & Soil?

1. Physical removal – Some pests big enough to see, you can just wash them off with water stream from a hose. For heavily infested stems or leaves you can just cut them off to stop the spread. Dispose of the cut stems & leaves safely far away from the plants.

2. Household Treatment for Houseplants – You can use 1 tbsp Mild liquid soap mixed with 1 liter of water to spray on the parts of the infested plants. The fatty acid in soap can break down the bug’s outer shell and kill them. Keep the plant away from direct sunlight as it can increase the chances of sunburn.

3. Natural treatment* – Neem oil is certainly one of the best natural solutions. Mix as per instructions (usually 2 tbsp Neem oil + 2-3 tsp mild liquid soap + 1 gallon of water) and spray on your infected plants & houseplant soil. It has a bit of pungent smell but surely kills & chases your bugs off your plants. Alternatively, you can use horticultural oil or organic insecticidal soap spray many of which also contains neem oil.

Neem oil solution is the most effective natural treatment that we highly recommend against any kind of houseplant bugs.

4. Systemic treatment for Houseplants – This solution involves the usage of chemical insecticides to kill the bugs and pests infecting the soil & plants. It can be sprayed on the plants or mixed with water & poured on the soil. Read instructions carefully before using them. Overdosing can kill your plants. Plus, make sure chemical drops don’t land on your skin as it can be harmful to humans. We do not recommend using this systemic method unless in extreme infestation cases.

How to Get Rid Of Bugs in Houseplants & Soil?

1. Fungus Gnats

1.1 How to identify Fungus Gnats in houseplant soil?

• Black insects, look like tiny mosquitoes or flies
• They’ve narrow legs & transparent wings
• Can fly around but stays close to the food source (fungi) in soil
• Adult gnats live about few days to a week
• Larvae look like long white or gray worms
• To check for infestation, shake the pot, if you see tiny flies scattering in swarms, its most likely fungus gnats

1.2 Facts about Fungus Gnats

• Fungus Gnats are mainly result of overwatering the plants
• Thrives & breeds in humid damp soil
• Cannot live long without water or moisture
• Reproduces quickly, lays egg in moist soil
• Lay ~300 eggs in a batch, hatches in 3 days, matures in 3 weeks
• Primarily eat fungi growing on damp soil
• Adult gnats are not very harmful to plants
• Their larva is most dangerous as they can feed on plant roots or root hairs
• This interrupts and hampers the plants ability to absorb nutrients & slows growth
• Causes plants to wilt

1.3 How to get rid of Fungus Gnats from Houseplants Soil?

The first step would be to isolate the infested plants from your other plants. I recommend to try out method 1 & 2 first, in conjunction with Method 6. This combined approach is usually enough to get rid of all fungus gnats for good. If infestation persists, look into the other methods.

Method 1: Dry them out (physical removal)

Stop watering the plant for a few days and dry out 1.5 inches from the top layer of the soil, this will kill most of the bugs (no treatment method). However, you can still water the plants from the bottom through the draining hole.

You can do that by pouring sufficient water into the saucer (water collector), sit the pot on it for 30 mins and then through away any remaining water. This way, the plant will get its required water though its deeper roots, while soil on top will continue to dry out killing the gnat larvae & eggs.

Method 2: Neem oil (natural treatment)

Pour neem oil or insecticidal soap solution (natural treatment) on the top part of the houseplant soil and spray the area thoroughly. For Neem solution, use 2 tbsp Neem oil + 2-3 tsp mild liquid soap + 1 gallon of water. Neem spray will kill and repel gnats as well. Apply treatment once every week, for 2-3 weeks.

Method 3: Diluted Hydrogen peroxide

If infestation persists, dry the top layer of soil. Then make a solution of 1 part “3% hydrogen peroxide” and 4 parts “Water”, let it rest for 30 minutes. Water your plants with it. Hydrogen peroxide solution will kill any Gnat larva or eggs in the soil.

The hydrogen peroxide mixture also helps kill any harmful bacteria and emerging fungi. Repeat this treatment once every week, for 2-3 weeks if needed.

Method 4: BT (Bacillus thuringiensis) (natural treatment)

BT is a natural occurring, soil-borne bacteria which does not harm human or pets. Take a few tbsp of BT & dilute with a gallon of water, leave the solution to infuse for at least a couple of days. Water the plants weekly with it, this will kill the gnats. Continue this treatment once a week, for 2-3 weeks if needed.

Method 5: Cinnamon & Chamomile Tea (natural treatment)

Just sprinkle a thin layer of cinnamon powder over the top layer of the houseplant soil. This actually kills the fungus that the larvae feed on, starving them to death. Repeat the sprinkling once every week, for 2-3 weeks.

Alongside sprinkling cinnamon, use Chamomile Tea to make the treatment stronger. Use 4 tbsp chamomile leaf to brew 32oz of tea, once cooled, mix it with 1 gallon of water. Use it to water the plants regularly, monitor regularly, and see if the gnats are dead within 2-3 weeks.

Method 6: Food Grade Diatomaceous earth (DE) (natural treatment)

DE is a fossilized shards of aquatic organisms that can kill fungus gnats by absorbing their oils and damaging their bodies with its sharpness. Dry out the top layer of the soil and add a layer of food-grade DE on top of the soil. I recommend wearing a mask while working with DE. Repeat the process once a week, for 3 weeks if needed.
