You should be concerned about termites if you notice any signs of their presence or if you live in an area known for termite activity. It’s important to take prompt action upon identifying signs such as discarded wings, mud tubes, hollow-sounding wood, small holes in wooden surfaces, or termite droppings. Additionally, if neighboring properties have experienced termite infestations or if you live in a region with a high termite risk, it is advisable to be proactive in termite prevention and conduct regular inspections to detect any early signs of infestation.
