DEET insect repellent – Once you have cleaned the house thoroughly, you can spray DEET insect repellent, which is readily available in stores. 

Use natural oils – Citronella, Eucalyptus, Lavender, Orange peel, or lemon act as an excellent repellent for sand gnats. You can either use their candle, oil, juice, or spray these natural products on sand gnats infested areas and repel them.

Salt – Salt dehydrates sand gnats. So by sprinkling salt on the carpets 24 hours before vacuuming, you can kill them quickly.

Method 2: Infested Area – Outdoors

Sand gnats living areas in the outdoors include garden, lawn, garbage can, etc. So to eliminate them give a quick go-through on the given methods below.

Boric acid – By adding some boric acid on the floor near the garbage can, you can control and get rid of sand gnats. 

Insecticides –  Insecticides can quickly eliminate sand gnats. Check out for insecticides with d-limonene and linalool as they are more effective against sand flies. While using insecticides, strictly follow the instructions carefully and keep children and pets away in the sprayed area for one or two hours. 

Citronella, Lavender, Eucalyptus Oil Spray – By using either of the sprays, you can control the infestation effectively.

Diatomaceous Earth – You can use Diatomaceous earth if your infested area is sand, soil, or moist. This chemical kills the sand gnats by drying them out by absorbing the oils and fats from the cuticle of the insect’s exoskeleton.
