Aphids
Aphids are small insects that live on plants and flowers, using them for food and harborage. They have long slender mouths used for sucking the juices out of plants. Signs of damage include curled, distorted leaves. Aphids also secrete a sticky substance called honeydew, which often turns black with the growth of a sooty mold fungus.
Slugs & Snails
Snails are mostly found in gardens and ground cover. They will stay in high moisture areas in order to survive. They can be very damaging to garden plants and citrus trees because plants are their primary food source. Signs of damage include holes in plant leaves or leaves entirely missing.
