Q.palm scale bug
My indoor palm has scale bug (found info on your site) and am treating it by washing with mild soapy water. My question is, will the scale bug affect the other plants I have in my house, some are right beside the palm? Thank you.
They can affect nearby plants so you may want to go ahead and treat all of them. Neem oil is an effective treatment as well. Here more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
