Ambrosia Beetle Control & Treatment Services in Metro Atlanta

Bugs and plants have always had a complex relationship on your property. While some insects help your greenery thrive, others can turn your outdoor sanctuary into a battleground. When your trees start showing mysterious signs of damage, the culprit might be lurking beneath the bark, slowly compromising the health of your beloved plants.

Among these hidden threats, ambrosia beetles rank as one of the most challenging pests to combat. These tiny but destructive insects bore deep into trees and plants, creating complex tunnel systems while introducing harmful fungi that can ultimately kill your trees. At Caldwell Tree Care, we've seen countless cases where these silent invaders have turned thriving properties into struggling landscapes. Our certified arborists can handle these annoying critters, providing Ambrosia beetles control and treatment that help your home.

What Are Ambrosia Beetles?

Granulate ambrosia beetles (Coleoptera) are small wood-boring insects that target both healthy and stressed trees. These persistent pests earned their name from the ambrosia fungus they carry and cultivate inside their tunnel systems. Unlike other wood-boring insects, the Asian ambrosia beetle doesn't actually eat the wood – instead, they feed on the fungus they introduce to the tree.

These beetles measure only about 2-3 millimeters in length, making them difficult to spot with the naked eye. Female beetles typically initiate the attack, boring into the tree's sapwood to create galleries where they'll lay their eggs. As they work, they produce characteristic frass and boring dust that often appears as thin strands or powder around entry holes. The relationship between the beetle and its fungus is a fascinating but destructive partnership. The adult granulate ambrosia beetle carries fungal spores in special structures in their bodies, deliberately introducing them to new trees as they excavate extensive galleries.

Signs Your Trees Are Under Attack

Detecting an ambrosia beetle attack early can make all the difference in saving your trees. Here are the key indicators that suggest your apparently healthy plants might be hosting these unwanted guests:

• Small, round entry holes (about the size of a toothpick)

• Strings of compacted sawdust protruding from bark

• Wilting or yellowing leaves

• Branch dieback

• Sudden plant collapse

• Visible frass tubes or sawdust around the trunk

• Dark staining around entry holes.

The presence of these symptoms often indicates that female granulate ambrosia beetles have already begun their invasion.

Trees and Plants at Risk

Ambrosia beetles show little discrimination when selecting their hosts, but certain species face higher risks of infestation. These destructive insects commonly target:

Fruit trees nut varieties
Dogwood
Magnolia
Golden rain trees
Japanese maple
Cherry trees
Peach trees
Sweet gum
Crape myrtle
Oak trees
Hickory
Maple species
Young or newly planted trees
Stressed or wounded trees

The Science Behind the Damage

When ambrosia beetles attack, they excavate extensive galleries and inoculate the wood with their symbiotic fungi. This process disrupts the tree's vascular system, preventing proper water and nutrient transport. The ambrosia fungus spreads through the wood, causing discoloration and decay that can extend far beyond the initial entry points. The damage pattern often appears suddenly, as trees can maintain their appearance until the fungal infection reaches a critical point. Once established, the combination of physical damage from tunneling and fungal growth can cause rapid decline, particularly in young or stressed trees.

Prevention and Control Strategies From Caldwell Tree Care

Protecting your trees from ambrosia beetle attacks requires a unique approach. To practice good techniques, start by maintaining optimal growing conditions for your trees. Proper irrigation, mulching, and fertilization help reduce stress, making trees less attractive to these opportunistic pests.

Monitor plantings for signs of early infestation, particularly during spring, when female granulate ambrosia beetles are most active. Inspection of trunks and branches, especially in young trees, can help identify potential problems before they become severe. When shot hole borer activity is detected, prompt action becomes critical. At Caldwell Tree Care, we use multiple strategies to address active infestations:

Chemical Control

We use targeted insecticide applications to protect vulnerable trees and control active infestations.

Cultural Management

We help implement stress reduction techniques and proper tree care practices to prevent future attacks.

Sanitation Measures

We remove infested plants or plant parts to prevent beetle populations from spreading to healthy trees.
