The answer to 'termite swarms' is that termite swarms are a common sign of an active termite infestation. Termites swarm, or emerge from their nests in large numbers, typically during the spring or fall months when temperatures and moisture levels are favorable. Swarms are the termites' way of reproducing and establishing new colonies.
Seeing termite swarms is a clear indication that you have a termite problem that needs to be addressed. Without prompt treatment, termites can cause significant structural damage to your home over time. While some homeowners attempt DIY termite control, it's generally best to call in a professional pest control technician who can properly identify the type of termites, locate the nest, and implement the most effective treatment strategy.
