The answer to 'ant swarms' is that ant swarms are a common pest problem that can occur when a colony of ants reproduces and produces winged reproductive ants, called alates, that swarm to mate and establish new colonies. Ant swarms are typically seen in the spring or fall and can be a nuisance for homeowners.
Common causes of ant swarms include warm, humid weather, the presence of food sources, and overcrowding in the existing colony. Symptoms include seeing large numbers of winged ants flying around, often in and around the home. Solutions can include sealing entry points, removing food sources, using baits or insecticides, and calling a professional pest control technician if the swarm is large or persistent.
