When the weather is warm and moist, termites emerge from their underground colonies to disperse themselves and begin building new colonies. They may emerge from their colonies either indoors or outdoors. The reason these termites are seeking new colonies is that their current colony has grown too large. Therefore, if you do see a termite swarm, it usually indicates an infestation and warrants immediate action. At Bayou Cajun Pest Control, we are experts at exterminating termites at their source and keeping your home protected.
