The answer to 'ant swarms' is that ant swarms are a common pest problem caused by the emergence of winged reproductive ants, known as alates, from an established ant colony. These swarms often occur in the spring or fall when the colony is ready to produce new queens and males to start new colonies. Symptoms of an ant swarm include seeing a large number of winged ants flying around, often near entry points to your home.
The best solution for an ant swarm is to treat the source colony to eliminate the entire population. This can be done through DIY methods like applying insecticide dust or baits, but for larger or more persistent infestations, it's best to call in a professional pest control technician. They have access to more powerful treatments and can properly identify the ant species to ensure the right approach. Preventing future swarms involves sealing cracks and entry points, removing sources of food and moisture, and maintaining good sanitation around your home.
