Or what would you recommend for gnats?… _MTA324さんが2025-12-11に投稿しました_ Do sticky traps really work? Or what would you recommend for gnats? I’ve done the need oil and it’s somewhat working. But my OCD is driving me insane when I see these little bugs flying around. I have way too many plants so I need some help. This is a quarter of what I have throughout the house. ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/vLMMUeU6iVE7Xgr8sJbQoPGh5wLdbJLMI2RjMWl0czU/ayYi-TlWSuejCXJZIa4VTQ.webp?size=large) ## 12件のコメント ### Kimmeryさんが2025-12-11にコメントしました They work for me. ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/ULmDKxIWxY5wVhxkzOnonrwAJ2WQD07PjrdDV9olfBU/TpFpcslsQtiTIL58qptd1g.webp?size=large) ### Gaiaさんが2025-12-11にコメントしました You can add peroxide the next time you water, 50/50 ratio. Also systemic granules in the soil work as well. 😊 ### Sunnyさんが2025-12-11にコメントしました You can buy nematodes or use the beneficial bacteria in Mosquito Bits granules and BMC Microbe Lift liquid. These work along with sticky traps to completely eradicate the gnats. Also, look at the soil mix that makes it easy for gnats to breed and grow. Continuously wet soil or soil with materials like moss are slow drying which creates the wet environment that supports the eggs. My 200+ plants don’t have peat moss in it. I have sphagnum moss in three propagations. But, I let those dry down so the top soil doesn’t support the gnat eggs which need moisture. 🪴🍀 ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/wefqOljjhEOiS9LRzOB1-QhxkVJiB4A5DGumXhnNrhs/Nx7bjBCgRNCu2XQ1-oHisw.webp?size=large) #### MTA324さんが2025-12-12に返信しました I’m going to look into this. I’ve been trying everything. I do have sphagnum moss so I hope that’s helpful. ### GreenJessさんが2025-12-11にコメントしました Traps work alright but it's only targeting adults. I used systemic granules in a few of my plants and the gnats were gone within 2 weeks. Now I use Arber's bio insecticide once every 4-5 weeks. I started using the arber spray on new plants and haven't had issues since. ### Greenthumbhopefulさんが2025-12-11にコメントしました Yes they work! ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/DXJ0Q_P4C7BxWdodM6iKvG9Rr6ETWe7U57IyyW9L3no/iuti8YHiRU2Rd5YHiUfuOA.webp?size=large) ### Whit\_Yさんが2025-12-11にコメントしました I use the sticky traps, a Zevo light, and bottom watering #### Tam’s Plantsさんが2025-12-12に返信しました I do the exact same thing but they also need a top watering about once every other month for a “flush” so I’ll do the hydrogen peroxide mix when I do that! ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/1EBr_Qz-UkHu-LL-nkDZUgYg9T8PWPZxEDFs8CaOdHM/GWHk-90RQ8uPKSj8xxdfSQ.webp?size=large) #### Whit\_Yさんが2025-12-12に返信しました This is such a great solution! I’ve been delaying my top water flush, but I’m definitely going to give this a try ☺️🌱 ### Stefanie Cooperさんが2025-12-11にコメントしました What I have found that works for my 150 plants is granules ### Kellyさんが2025-12-12にコメントしました The zevo light worked for me. Your plants are beautiful btw! ### lozさんが2025-12-15にコメントしました Depending on how bad the issue is. Pretty bad: BTI or granules diluted in water (kills the entire lifecycle after a few weeks). If it’s not too bad YET, one I don’t see talked about often enough is potting sand being added to the surface layer. Makes the soil unliveable for them. Personally, that’s all I needed \& haven’t seen a gnat for months now. --- _Plantaコミュニティ (https://getplanta.com)。閲覧はどなたでも可能です。投稿、コメント、いいねをするには、Plantaアプリをダウンロードしてください: https://getplanta.com/download_
