I have a sago palm that flowered last year, and now a new set of fronds are beginning to emerge in the middle of the opened flower. I decided I needed to pull off as much as possible of the flower remnants to allow the fronds to grow/spread. However, once I started pulling pieces off I have run into carpenter ants. What could I use to spray the ants without hurting the sago palm/new frond growth? See pic. Thanks!!
