Depending on where you live, you may notice a bit more aggression from hornets and wasps these days. This is due to the change in season and the life cycle of the insects and their nests, experts say.
Crowding and a diminishing food supply could cause wasps to be more aggressive to anyone that seems to be a threat to their colony. Additionally, insects are cold-blooded and seek the heat, which leads them to buildings, including homes. It is important to call a professional to deal with nests in or near your house, especially for older people, who should avoid getting stung.
