Is termite harmful to humans?

Termites are not directly harmful to humans in terms of biting, stinging, or transmitting diseases like mosquitoes or ticks, but they can be indirectly harmful through structural damage, allergies, and bites in rare cases. Subterranean termites, which cause over five billion dollars in structural damage annually in the United States, do not bite people and their primary harm is eating wood from the inside out, hollowing out studs, floor joists, and support beams, which can cause sagging floors, collapsed structures, and costly repairs that create safety hazards if homes become structurally unsound. Drywood termites also do not bite humans. However, termite infestations can cause indirect health issues, as termite droppings and frass which look like sawdust can trigger allergies and asthma in sensitive individuals, and the dust from damaged wood and mold that grows in moist conditions favored by termites can irritate lungs. Soldier termites can bite if handled, but their jaws are small and bites are not venomous and rarely break skin, causing only minor irritation. Termites are not known to transmit diseases to humans. The main harm is economic and structural rather than medical, though the stress and financial burden of discovering termites can affect mental health. While termites are not dangerous like wasps or venomous spiders, they should be treated promptly by professionals with liquid barriers or bait systems costing $1,000 to $3,000 because prolonged damage can make homes unsafe. So they are harmful to houses, not directly harmful to humans through bites or disease.
