Late August Is Peak Wasp Season in the Magic Valley
If wasps and yellowjackets seem more aggressive lately — you're not imagining it. August is the most active time of year for stinging insects in Southern Idaho, and here's why.
By mid-to-late summer, wasp and yellowjacket colonies have reached their largest size of the year — sometimes thousands of individuals. Their food preferences also shift toward sweets, which is why they crash backyard BBQs, hover around trash cans, and dive-bomb your lemonade. They're also at their most defensive as summer winds down and colonies prepare for the season ahead.
Common things that attract them to your yard:
• Outdoor food and sugary drinks left uncovered
• Unsealed or overflowing garbage cans
• Fallen fruit from trees
• Undisturbed eaves, decks, and sheds where nests can grow
A few simple steps that help:
✔ Keep food and drinks covered when eating outside
✔ Seal trash cans tightly
✔ Pick up fallen fruit regularly
✔ Check eaves, rafters, and under decks for early-stage nests
If you've already found a nest or are seeing heavy wasp activity around your home or business, don't attempt to remove it yourself — active nests can be dangerous. Our team safely eliminates nests and helps prevent them from coming back.
