My mom recently passed away. I am trying to take care of her flowers. In these flowers she has about 10 exotic Desert Roses. They where doing just fine through 2 moves and 2 hurricanes - but now seem to have attracted some sort of creepy crawly. I in no way shape or form inherited my mom's ability to care for plants so I am in the dark with how to get rid of these creatures. As you can imagine I am concerned that I will ruin her plants - that would break my heart. Can someone help me. I am attaching a picture of the pest. I was going to do soapy water and spray them - but becuase they are so special I want to hear from the experts first.
Thank you in advance for any tips or tricks.
