I treated group 1 again (12/24), most had no webbing only my 2 Pink Princesses had webbing still and it was only 1-3 strands. ![4件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/vMUqGY1bLQZ54FatyNkwHYCMVuKEcOwSMMFlPMHN6Lo/P-ufOGOaR1OLw5fMt4gI9g.webp?size=large) ![4件中2件目の添付ファイル](https://images.getplanta.com/v1/resize/vMUqGY1bLQZ54FatyNkwHYCMVuKEcOwSMMFlPMHN6Lo/btrFBKovQwOMpjDReyD2Sg.webp?size=large) ![4件中3件目の添付ファイル](https://images.getplanta.com/v1/resize/vMUqGY1bLQZ54FatyNkwHYCMVuKEcOwSMMFlPMHN6Lo/ItpLFi6_R1uhffNzvk9HMw.webp?size=large) ![4件中4件目の添付ファイル](https://images.getplanta.com/v1/resize/vMUqGY1bLQZ54FatyNkwHYCMVuKEcOwSMMFlPMHN6Lo/y26t_HbETyq58FNVpcOyrA.webp?size=large) ## 15件のコメント ### Debbieさんが2025-12-23にコメントしました Spray with 70% rubbing alcohol also. Every couple of days. It kills instantly. Then weekly/every other week #### Jeremy\&Angieさんが2025-12-24に返信しました This is the way^^^ive done it countless and countless times and it works instantly and I’ve never had a plant show any signs of illness from doing so. I use 91% alcohol but I do dilute it with water at roughly 1 part water to 2 parts 91% alcohol. 100% success rate. ### Philさんが2025-12-23にコメントしました I would be devastated. Luckily I’ve only dealt with them one time on two plants. I just took them in the shower and sprayed them down every couple days for about 10. They are not difficult to get rid of. It’s just dealing with them on so many. Please post back with an update in 2 weeks. ### Sunnyさんが2025-12-23にコメントしました Washing them down and spray using insecticidal soap is preferable over spraying rubbing alcohol onto the plants. Many plants will die from soaking rubbing alcohol onto the plants and soil. 🪴🍀 #### Debbieさんが2025-12-23に返信しました Have yet to have an issue and do it weekly. Have had no pests either. I follow a plant shop owner who recommends this. @therootedplantshop #### Madsさんが2025-12-23に返信しました Can attest to this… killed a mini Sinningia \& some Peperomia this way. 😭 #### Debbieさんが2025-12-24に返信しました Yea definitely don’t do succulents or tradscantia (sp?) ### Random Strandsさんが2025-12-23にコメントしました I use this from Paige Tailyn - she is hip on plants - this worked for me. Do be careful with straight alcohol as some plants can not handle it. Although it can help. After any spray down keep the light off of them. - good luck - it sucks. Keep at it they will be taken away. ![1件中1件目の添付ファイル](https://images.getplanta.com/v1/resize/dFTRZjytlJKSDUUb9ce9emdyN122S9l_Ydn7f5YfoJE/XY43uBueSoeeZCBbLHOz2A.webp?size=large) ### Crazy plant ladyさんが2025-12-23にコメントしました I busted used a Q tip with 71% rubbing alcohol and wiped where the webs were down and let it dry ### Ryanさんが2025-12-23にコメントしました What’s a spider mite? #### Yuleafさんが2025-12-23に返信しました they’re microscopic arachnids type pests that make webbing on your plants \& feed on them. if let untreated they spread \& kill ur plants :( #### Ryanさんが2025-12-23に返信しました Oh no! That sounds horrible! I’m so sorry for your plants! ### Madsさんが2025-12-23にコメントしました For long term treatment \& prevention, and/or a large scale infestation, I recommend predatory mites. I introduced some in early November for a persistent spider mite problem and (fingers crossed) have had zero spider mites since. !! Then in early December I got thrips (😭), so got another round of predatory mites, and thrips are all gone! Plants that had a bad thrips outbreak I sprayed down with Castile soap solution periodically. #### Mayaさんが2026-03-28に返信しました Is there a link to where we may be able to find them? #### Madsさんが2026-03-29に返信しました www dot naturesgoodguys dot com Or of course, Amazon. --- _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_
