Understanding Wasps
Social wasps, including hornets and yellow jackets, are often considered beneficial insects. They act as predators, feeding on many pest worms and caterpillars that can harm your garden. However, wasps can become a problem when they nest near people or scavenge for food later in the season.
When to Leave Them Be
If a wasp nest is located in an area where it doesn’t interfere with people, pets, or livestock, it’s best to leave them alone and let them provide natural pest control. Social wasp colonies only last for one season, as frost kills all but the overwintering queens.
Preventing Wasps
- Seal Entry Points: Use caulk to close holes or openings in structures where wasps could enter, such as attics or walls.
- Decoys: Hang a decoy like the Waspinator to discourage territorial wasps, such as paper wasps, from nesting in your area.
- Monitor Early Spring Activity: Look for wasps building nests under eaves, around entryways, or in holes in the ground. Early detection makes control easier.
Controlling Wasps
For small nests, you can control wasps on your own using natural sprays. Products like the WHY spray contain ingredients such as lemongrass oil, clove oil, rosemary oil, and geranium oil. Follow these steps:
- Wait until after dark or early morning, when wasps are sluggish, to approach the nest.
- Wear protective clothing, such as long sleeves, pants, gloves, and a veil.
- Spray the nest thoroughly and check back in the morning to ensure the nest is gone.
- Repeat the process every 3 days, if necessary.
Removing Nests
If you need to remove a small wasp nest, wear protective gear and carefully place the nest in a sealed plastic bag. Then, put the bag in the freezer or leave it in the sun to kill the wasps. For larger nests, it’s best to hire a professional exterminator to ensure safe removal.
Dealing with Scavenging Wasps
In late summer, wasps stop hunting and start scavenging for food, making them a nuisance during outdoor activities. Use traps with lures to reduce their presence:
- Hang traps away from your gathering area.
- Place traps in the pathway that wasps take to your event for the best results.
Conclusion
Wasps can be both beneficial and problematic, depending on their location and behavior. Use these tips to manage wasps effectively, and enjoy the outdoors without worry. Grow organic for life!
