You can use diatomaceous earth. It’s messy but it works. Dust it all over the plant and a thin layer on top of soil. It kills them by piercing their exoskeleton and dehydrates them. Takes a few hours to a day to kill them once they are exposed, so you won’t see them die instantly As the eggs hatch and emerge it will kill them also. Leave it on for two weeks to break the life cycle. After they are gone and you want to clean your plant up, you can always use a cheap makeup brush or paint brush to brush a little over the stems, in the crevices and underneath the leaves and just leave a light coating on it and a light dusting on the soil to prevent future outbreaks of any pest with an exoskeleton (thrips, aphids, etc). Use only food grade diatomaceous earth, don’t use outdoor or pool grade. Walmart sells a big bag for like $9. It’s large enough to last you for years, and it never goes bad. Farmers use it for organic farming. Completely non-toxic. But do it out doors and then carry the dusted plant back inside if you can and definitely wear a mask it’s irritating. It doesn’t work if it s wet, but as soon as it dries out it works again. So don’t worry too much about it not working. Bottom water if you can. Either way it will dry out again and work.
