But I have no idea what it is and how to treat it. ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/Q3jLYkTwDl-Yu1P_a1B2HQFhBGZr01o0SZnAe9Vp9lw/VvQqMigxT-qIxAXNgD-ycQ.webp?size=large) ## 14件のコメント ### Samさんが2024-04-16にコメントしました Looks like mealy bugs to me #### Tylerさんが2024-04-16に返信しました Thank you ### Plant momさんが2024-04-16にコメントしました Yeah, I agree or it might be Spider mites I haven’t really seen with Spider mites but I don’t know if that’s them but yeah, I would definitely get pest spray. Soak them in there spray them with it. #### Tylerさんが2024-04-16に返信しました Does Neem oil work? #### Plant Addictさんが2024-04-17に返信しました I wouldn’t say spider mites. They look pretty different and there would be tiny webbing and they are difficult to spot. Looks like mealy bugs, larger and cotton-like. #### Plant Addictさんが2024-04-17に返信しました I haven’t had luck with neem oil but an insecticidal soap, systemic, and isopropyl alcohol all work well for mealy bois. I personally spray the isopropyl on when dealing with mealy bugs because they are easy to miss but people don’t particularly like that. Idk, my boss has a degree in horticulture, she does it, I do it, it works lol 🤷‍♀️ ### Plant momさんが2024-04-16にコメントしました Yes it dose #### Tylerさんが2024-04-16に返信しました Thank you #### Plant momさんが2024-04-16に返信しました Just glad to help ! ### Plant momさんが2024-04-16にコメントしました Does\* ### Plant momさんが2024-04-16にコメントしました You might want to quarantine that plant after you do it so that way your other plants don’t get spider mites or whatever that it is on them or you might want to do the same thing putting neem oil them but either works. I’m just saying for my experience with that. ### Tee Jayさんが2024-04-17にコメントしました Oh no! It’s mealybug. You can spray them directly with 70% alcohol and squish them with a q tip. Treat the rest of the plant with insecticidal soap. Keep treating because they are tough to get rid of. Clean around the pot too because they like to form cocoons almost anywhere on and around the plant. ### S.Rさんが2024-04-17にコメントしました Mealybugs! You can see their little bodies if you zoom in on the photo. Tanya has good tips in the post above 👆🏻 ### Samさんが2024-04-17にコメントしました When I had mealy bugs I used rubbing alcohol on a cotton swab to kill them. And a spray the plant with them. --- _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_
