What Causes the Sticky Liquid Oozing Out of Trees?


Insect Infestations


  • Aphids: These small insects feed on tree sap, causing it to ooze out.

  • Scale Insects: Similar to aphids, scale insects also feed on tree sap, resulting in sticky liquid.

  • Leafhoppers: These insects pierce tree leaves and extract sap, leading to sap leakage.

Bacterial or Fungal Infections


  • Fire Blight: A bacterial infection that causes sap to ooze out accompanied by darkening and discoloration.

  • Wetwood: A bacterial infection that leads to the formation of a liquid-filled cavity in the tree, resulting in sap leakage.

  • Ganoderma Root Rot: A fungal infection that affects the tree's roots and causes sap to ooze.

Sap Leakage


Sap leakage can occur naturally as a result of tree growth or damage to the bark. This can lead to the presence of sticky liquid on the tree's surface.


Environmental Factors

  • Excessive Heat: High temperatures can cause increased sap flow, leading to oozing.

  • Freezing and Thawing: Fluctuations in temperature can disrupt the tree's circulatory system, causing sap to leak.

  • Physical Damage: Injuries to the tree, such as broken branches or wounds from pruning, can result in sap oozing.


Insect Infestations


  • Aphids: These small insects commonly feed on the sap of trees, causing oozing or dripping liquid.

  • Scale Insects: Scale insects can attach themselves to tree branches and trunks, feeding on sap and causing liquid oozing.

  • Whiteflies: These tiny insects suck sap from the leaves of trees, leading to sticky liquid secretion.

  • Caterpillars: Certain caterpillar species can produce a sticky substance while feeding on tree foliage.

  • Boring Insects: Borers tunnel into tree trunks, creating entry points for disease organisms and causing sap leakage.


Insect infestations can weaken trees and make them more susceptible to diseases and other problems. If not addressed, these infestations can lead to significant damage or even tree death. It is important to identify and control insect populations to prevent the oozing of sticky liquid and protect tree health.

Bacterial or Fungal Infections


  • Fire Blight: A bacterial infection commonly affecting trees in the Rosaceae family, such as apple, pear, and cherry trees. It causes wilting, blackening, and ooze production.

  • Wetwood: Also known as slime flux, wetwood is a condition caused by anaerobic bacteria. It results in the accumulation of fermented sap and foul-smelling ooze.

  • Bacterial Canker: This infection causes cankers on tree trunks and branches, leading to oozing and the formation of dark, sunken areas.

  • Verticillium Wilt: A fungal disease that affects a wide range of trees, including maple, ash, and oak. It leads to wilting, browning, and oozing.

  • Peach Gummosis: A fungal infection common in peach and apricot trees, causing gummosis or the exudation of gum-like sap from wounds or cankers.


Bacterial or fungal infections can weaken trees and cause oozing of sticky liquid, which can attract pests and further damage the tree. It is important to identify and address these infections promptly to prevent lasting damage or tree death.

Sap Leakage


Sap leakage is another common cause of sticky liquid oozing out of trees. Sap is the nutrient-rich liquid that flows through a tree's circulatory system, carrying nutrients and water from the roots to the rest of the tree. Under normal circumstances, sap is contained within the tree and is not visible on the exterior.


However, certain conditions or factors can cause sap leakage, leading to sticky liquid oozing out of trees. These conditions include:


  • Damage to the tree bark: When the tree's bark is damaged, such as through physical injury or disease, it can disrupt the flow of sap and cause it to leak out.

  • Sap-feeding insects: Some insects, such as aphids or certain types of beetles, feed on sap by piercing the tree's bark and extracting the nutrients. This can lead to excess sap production and leakage.

  • Improper pruning practices: Incorrect pruning techniques, such as removing too much bark or cutting into the cambium layer, can damage the tree and result in sap leakage.


In most cases, sap leakage does not pose a significant threat to the health of the tree. However, it can attract other pests or fungi and create a sticky mess on nearby surfaces. If you notice sap leakage from a tree, it is recommended to assess the underlying cause and take appropriate measures to address it.


In the next section, we will discuss potential solutions to address the issue of sticky liquid oozing out of trees, including ways to control insect infestations and treat bacterial or fungal infections.


Environmental Factors


  • Extreme Temperatures: High temperatures can cause the sap in trees to become more fluid and increase the likelihood of it oozing out.

  • Physical Damage: Injury to the bark or the tree itself, whether from pruning, wind, or other factors, can lead to sap leakage.

  • Tree Stress: Environmental stressors such as drought, nutrient deficiencies, or changes in soil conditions can cause trees to produce more sap in an attempt to protect themselves.

  • Invasive Species: Certain invasive insects or diseases can cause trees to produce excessive amounts of sap as a defense mechanism.

  • Tree Age: Older trees may naturally produce more sap, especially during periods of growth or in response to environmental triggers.


Understanding these environmental factors can help identify the cause of sap oozing from trees and determine the appropriate course of action to address the issue.


How Does the Sticky Liquid Affect Tree Health and Surroundings?


The sticky liquid oozing out of trees can have various effects on the health of the tree itself and its surroundings. Understanding these effects can help in addressing the issue effectively. Here are some potential impacts of the sticky liquid:


  • Attracts Insects: The sticky liquid, often referred to as "sap," can attract insects such as aphids, beetles, or ants. These insects may feed on the sap or use it as a breeding ground, further affecting the tree's health.

  • Leads to Sooty Mold: The sugary substance in the sap can promote the growth of sooty mold, a black or dark green fungus. Sooty mold can cover leaves and branches, blocking sunlight and impairing the tree's ability to carry out photosynthesis.

  • Weakens the Tree: Excessive sap loss can weaken the tree by depleting its energy reserves. It may lead to defoliation, stunted growth, or even dieback of branches.

  • Stains and Damages Surfaces: The sticky liquid can stain and damage surfaces under the tree, such as cars, walkways, or outdoor furniture. It can be difficult to remove and may require cleaning or repairs.

  • Indicates Underlying Issues: The presence of sticky liquid may indicate underlying problems such as insect infestations, bacterial or fungal infections, or sap leakage. Addressing these issues promptly is crucial to prevent further damage to the tree.


It is important to monitor the impact of the sticky liquid on the tree's health and take appropriate measures to address the underlying causes. In the next section, we will discuss potential solutions to address the issue of sticky liquid oozing out of trees and mitigate its effects.
