Understanding when and why wasps become defensive can help reduce the risk of stings for you and unnecessary disturbance for wasps.<br>Wasps are least aggressive in spring and early summer. During this period, nests are still small and activity is focused on building and feeding larvae. Worker wasps are busy and usually avoid confrontation unless their nest is threatened.<br>Defensiveness tends to increase in late summer and early autumn. By this time, nests are much larger and wasps become more protective. At the same time, their natural food sources are declining. As a result, wasps are more likely to follow people, attracted to sweet foods, drinks, and waste. It is important to understand that wasps are not \u201cangry\u201d or purposely try to hurt a human &#8211; they are simply competing for limited resources.<br>Wasps can also become defensive when they feel their nest is threatened. Vibrations, loud noises, or attempts to remove a nest can trigger aggressive behavior, even earlier in the season. For people with allergies, children, or pets, this risk is especially important to consider.<br>If wasp activity is increasing or a nest is located near your home or business, professional advice is recommended. Early, safe intervention helps prevent escalation later in the season. Contact iRotec for expert guidance or a professional inspection and deal with wasp problems calmly, safely, and effectively.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Wasps are often seen as aggressive, but their behaviour changes throughout the year.
