# Hey all! Unfortunately my new plants (sweet mint \& rosemary) were…

Hey all!

Unfortunately my new plants (sweet mint \& rosemary) were bought infected with thrips. They’re not very big and don’t have a lot of growth, but I aggressively removed infected/damaged leaves anyway. I was advised that dish soap (dawn), neem oil, and hydrogen peroxide (3%) is a good mix for getting rid of these guys, and so far so good! I actually don’t have neem oil on hand, so it’s just dawn and hydrogen peroxide, but it seems to be doing the trick. My next spray mixture will have neem oil in it, I was just desperately trying to get a head of these pests because it seemed like they did a lot of damage just over night. My partner and I can’t see many, if any, adults left on the plants as I’ve been misting them 1-2 times a day and physically wiping off areas that seemed like hotspots. I’ve also been misting the soil with the mix just in case there’s eggs/larva.

Anyway, is there anything else I could be or should be doing? What about prevention for the future? I’m worried that they might die because I bought and repotted them 6 days ago, so they’ve already been through a lot of stress. The sweet mint was literally growing like a weed for the first 3 days before I noticed the damage on the leaves. But it felt like a trade off between constant damage over time from thrips, or a bit of damage/stress from treatment and leaf removal to get rid of them quickly and letting the plant heal after. I read eggs/larva can get into the soil so that protects them from the mix, so that’s why I’ve continued to mist them at least once a day to keep those from turning into more breeding adults. When would I repot these guys to give them fresh, pest free soil, or is repotting not necessary if all of the thrips are dead? Would I rinse off/soak the roots in water as well? I’d be worried about breakage since they have thin roots, but I repotted them with the soil they came with + adding well draining soil in the surrounding areas since these pots are bigger than what they were in, so I’m wondering about how deep thrip infestation can be.

Thank you all!

Ugh that sounds like a ton of work youve gone through. Once most if not all the adult thrips are gone, I’d repot with fully fresh soil, not reusing any old soil. Definitely rinse off the roots with water and treat them with neem oil and water. That way you have a better chance of getting rid of the eggs/larvae. Also, wash out the pots they’ve been in before repotting with water and hydrogen peroxide and soap.
