Aphids are insects that have an elongated body, a pair of compound eyes, and a mouth-like opening on the back. Aphids are commonly found on plants and are known to cause great damage to crops. Aphids feed by piercing plant cells with their mouthparts and sucking out plant juices. This can result in the loss of large amounts of water from the plant and may lead to cell death.
The first thing you need to know about woolly aphids is that they are not harmful to humans. They feed on plants and flowers, but it’s a very small amount of damage that they cause. You can remove them from your garden with a strong blast of water or a squirt of soap. If you spray your plants, make sure you spray the plants that are being eaten by the aphids.
