The answer to 'fence pests' is that common fence pests include termites, carpenter ants, and wood-boring beetles. These pests can damage the structural integrity of your fence, leading to instability and potential collapse. Symptoms include visible damage to the wood, sawdust or droppings, and weakened or hollow sections.
For minor pest issues, you may be able to treat the problem yourself using targeted insecticides or wood preservatives. However, for more severe infestations or if the fence is compromised, it's best to call a professional pest control technician. They can properly identify the pest, apply the appropriate treatments, and assess whether the fence needs to be repaired or replaced.
