If faced with a swarm, vacuuming up the flying insects is the safest and quickest method for removal. The next step is to properly identify the pests and ensure that they are not termites. To do this, you could crush one and check for the lemon scent or contact a pest expert.
Nests can be eliminated through the use of insecticides. To ensure the removal of any interior infestations, though, you must find and repair the water leaks or moisture problems that attracted the ants inside. Standard exclusionary methods, such as sealing small cracks with caulk and storing firewood away from the home, are also recommended.
