The Sticky Truth About Honeydew
Honeydew is produced by aphids and scale, two common insects that feed on sap from trees and plants. Aphids are small, soft-bodied insects that feed on plant sap, while scale are armored insects that secrete honeydew as a waste product. When these insects feed, they excrete honeydew, which can fall from the tree and onto nearby surfaces. The sticky substance can be a nuisance, but it can also indicate a larger problem with your plant’s health.
Is Honeydew Harmful to Trees?
While honeydew itself isn’t toxic to trees, it can be a sign of a larger issue. Aphids and scale can weaken trees by sucking sap and transmitting plant viruses. If left unchecked, infestations can lead to stunted growth, curled leaves, and reduced fruit production. Regularly inspecting your trees for signs of infestation can help prevent honeydew production and keep your trees healthy.
Preventing Honeydew from Falling on Your Outdoor Furniture
Preventing honeydew from falling on your outdoor furniture involves managing the insect population, using physical barriers, and maintaining good garden hygiene. Start by inspecting your plants regularly for signs of infestation. Remove any infested branches or leaves, and treat your plants with insecticidal soap or neem oil to control aphid and scale populations. Use physical barriers like fine-mesh screens or fine-netting to keep insects away from your outdoor furniture. Finally, maintain good garden hygiene by cleaning up debris and leaf litter, which can attract insects.
Can Honeydew Attract Other Pests?
Yes, honeydew can attract other pests like ants, bees, and wasps. These insects are attracted to the sweet, sticky substance and can end up infesting your plants or even your home. Regularly cleaning up honeydew and controlling the insect population can help prevent other pests from being attracted to your property.

How Do I Know If the Honeydew Falling from Trees Is from Aphids or Scale Insects?
To determine whether honeydew is coming from aphids or scale insects, look for the insects themselves. Aphids are small, soft-bodied insects that feed on plant sap, while scale are armored insects that secrete honeydew as a waste product. If you see aphids on your plants, it’s likely they’re producing honeydew. If you see scale, it’s likely they’re producing honeydew as well.
