Answer: Unfortunately, without knowing which plant this is and a description of the pest it is very difficult to make a recommendation. Many insects on houseplants can be controlled using the commercially formulated insecticidal soap. Be sure to read and carefully follow all of the label directions and apply and reapply as indicated on the label. Some plants are sensitive to sprays and can have a bad reaction, so you might test the soap spray on a leaf or two before you spray the entire plant. I hope this helps!
