Aphids cluster on buds, leaves and tips of shoots. They feed on plant juices causing poor plant growth and distorted leaves. They're attracted to light and tend to swarm around windows when inside. Immature larvae are whitish maggots and tunnel into soil, destroying plant roots. Plants wilt, yellow or develop mold on surface.
Mites suck plant juices, causing whitish or yellowish speckled areas on tops of leaves.
Heavy infestations produce frail, silky webbing and can cause plant to die. They resemble bits of ash when plant is moved. They feed by sucking juices from leaves. Infested leaves may turn yellow, die or drop off and are covered with sticky substance. Foliage curls and yellows.
