The larval stage of white-Horned Horntail is known for boring into wood, which can cause significant damage to trees and timber used in construction. Their tunneling weakens the structural integrity of the wood, leading to a compromised structure and potential hazards, especially if they affect load-bearing elements or crucial wooden infrastructure.

To deter white-Horned Horntail infestation, it is advisable to use wood that is less attractive to them or treated with repellents. Keeping wooden structures dry and well-maintained reduces the likelihood of white-Horned Horntail intrusion. Physical barriers, like metal mesh, can also prevent white-Horned Horntail from accessing susceptible wood areas.

After troubles with white-Horned Horntail occur, removing the affected wood and replacing it with new, untreated wood is critical. Applying insect growth regulators to infested areas could disrupt larval development. Ensuring proper ventilation and reducing moisture can also help to mitigate further damage. During recovery, regularly inspecting for new signs of activity will help prevent reinfestation. It's important to engage professional pest control services for comprehensive treatment and advice tailored to the specific situation.

The larval stage of white-Horned Horntail poses a threat to wooden structures as it bores into the wood, compromising structural integrity. This can range from mild surface damage to severe weakening of support beams, potentially necessitating costly repairs or replacements.

White-Horned Horntail inflict damage primarily during the larval stage by boring into stems and roots of coniferous trees, disrupting the flow of nutrients. Adult activities may lead to spread. In mild cases, growth is stunted; in severe infestations, trees can die. This may also impact timber production and forest ecosystems.
