The answer to 'wasp swarms' is that wasp swarms are a common problem that can occur when a wasp nest becomes overcrowded or the colony is preparing to split and create a new nest. Symptoms include seeing a large number of wasps flying together in a coordinated group, often near an existing nest or potential nesting site. Solutions depend on the severity of the swarm and location, but may involve removing the nest, using insecticides, or calling a professional pest control company.
Wasp swarms can be dangerous due to the large number of stinging insects, so it's important to address the problem quickly and safely. DIY solutions like spraying insecticides may be effective for small swarms, but larger or hard-to-reach swarms should be handled by a licensed pest control professional.
