How to Get Rid of Borers in Your Garden

Borers are a common pest in gardens and can cause significant damage to plants, including wilting, yellowing of leaves, and eventually death of the plant.

To effectively get rid of borers in your garden, it is important to first identify the specific type of borer insect present. Look for signs such as tiny holes in the stems or trunks of plants, sawdust-like frass on the ground, or wilting and yellowing leaves. Once you have identified the pest, you can treat infested plants by removing and destroying the affected areas, such as cutting out infested stems or branches.

What are Borers & How to Get Rid of Them

Borers are a type of insect that can cause serious damage to trees or plants by tunneling into the trunks, resulting in stunted growth, wilting, and even death. There are several types of borers, including flat-headed borers, round-headed borers, and bronze birch borers, each with their own unique characteristics and preferred hosts.

Most species of borers are attracted to weakened, dying, or dead trees and plants as they play a crucial role in the decomposition cycle. To prevent borers from targeting your trees or garden, it is important to keep them healthy and well-maintained by regularly watering, fertilising, and pruning them. Additionally, keeping the area around the tree and garden free from debris and controlling other pests that may weaken the trees or plants can also help prevent a borer infestation.

Life Cycle of a Borer

The life cycle of a borer consists of four stages: eggs, larvae, pupa, and adult.

The cycle begins with the laying of eggs by the adult borer on the host plant. These eggs are typically laid on the surface or within the tissues of the plant. The eggs then hatch into larvae, which are the destructive stage of the borer. The larvae bore into the host plant, feeding on its tissues and causing damage.

After the feeding stage, the larvae enter the pupa stage, where they undergo metamorphosis. During this stage, the larvae transform into adults inside a protective cocoon. Finally, the adult borer emerges from the pupa and begins the cycle again by laying eggs on a new host plant.

At each stage of the life cycle, the borer exhibits specific actions and behaviours. The eggs are laid on the host plant, the larvae feed and bore into the plant, the pupa undergoes metamorphosis, and the adult reproduces by laying eggs. The life cycle of a borer is a continuous process of infestation and reproduction, causing damage to the host plants.

Host Plants

Borers are known to attack a variety of host plants, including several primary trees and crops. The peach tree borer primarily targets stone fruit trees such as peaches, plums, and cherries, while the eucalyptus borer prefers eucalyptus trees. The corn borer targets corn and other cereal crops, and the sugar cane borer attacks sugar cane plants.

Regional variations in New Zealand, such as climate and soil conditions, influence the choice of host plants for borers. For instance, the warmer temperatures in the northern regions make them more susceptible to borers that target specific crops like avocado and citrus. On the other hand, the cooler climates in the South Island may result in different host plants being targeted by borers, such as eucalyptus trees.

Effective Borer Control with Flick Pest Control

Borer control in New Zealand is crucial for protecting gardens and trees from the damage caused by borer species. Preventative measures include regularly inspecting plants and trees for signs of infestation, such as small holes, frass (sawdust-like material), and weakened or dead branches. Applying a protective barrier or sealant to vulnerable areas can also help prevent infestations.
