Some common pests to look out for include: Mealy bugsProbably the most common pest of houseplants, mealy bugs are sap-sucking insect that look like patches of white cotton wool. They are difficult to eradicate as they often hide in relatively inaccessible places, but our spray will help get them under control quickly. Red spider mitesIt’s difficult to see these sap-sucking pests by eye, but their damage is unmistakable. The upper sides of leaves will become mottled, before they shrivel up and die – fine webbing is sometimes visible.. They like hot, dry conditions so mist plants regularly to raise humidity. Scale insectsScale insects are sap-sucking creatures that look like tiny brown limpets. Over time, they form large colonies and will weaken their host. They usually appear on stems and under leaves.
