Avoiding Underground Yellowjacket Nests: A Gardening Expert Provides Useful Advice to Deter Wasps
In the summer months, yellowjackets (Gelbjacken in German gardens) can become a nuisance for homeowners. These aggressive insects are attracted to sweet or protein-rich food sources and can pose a threat to both humans and pets. Here's a guide on how to deal with yellowjackets safely and effectively.
Safety first
When approaching yellowjacket nests, it's crucial to wear protective clothing and approach with caution. Aggressive approaches with wasp spray can be dangerous due to yellowjackets' ability to sting multiple times and release pheromones.
Creating a scent barrier
Using a light clove and geranium oil spray can help create a scent barrier against yellowjackets. Additionally, aromatic herbs such as mint, lemon balm, sage, thyme, and lavender, known for their strong scents, are often recommended for repelling yellowjackets.
Controlling food sources
Keeping spaces sanitary can help deter yellowjackets. Spilled soda, dropped fruit, meat scraps, and forgotten pet snacks can attract yellowjackets. Controlling food sources, both early (protein) and late (sugar), can keep yellowjackets off property.
DIY yellowjacket traps
DIY yellowjacket traps can be made to control yellowjacket populations. Protein or sugar-based yellowjacket traps can help keep yellowjackets away from picnic and patio areas.
Professional help
It is best to safely deal with an aggressive yellowjacket colony by calling a professional pest control service. Coordinated efforts with neighbors can help keep yellowjackets away from the whole block.
Preventing yellowjacket nesting
Shelter is important for yellowjackets, as they prefer spots like mulch piles, thick shrubs, deck boards, old pots, and quiet, hidden areas. Check under sheds, along fence lines, and in overgrown corners in early spring to prevent yellowjackets from nesting. Some seemingly harmless spots, such as under garden furniture cushions, beneath tarps covering seasonal tools, and inside decorative rock piles, can be perfect for yellowjackets to nest.
Natural repellents
Coffee can be used as a natural yellowjacket repellent, and using mint, thyme, or lemongrass plants can repel yellowjackets around patios and seating areas. Controlling aphid populations with a homemade spray or attracting ladybugs to the garden can help deter yellowjackets.
A pre-made spray like the one from STEM, available on Amazon, can also be used as a yellowjacket repellent.
In conclusion, a combination of safety measures, food source control, DIY traps, natural repellents, and professional help can help homeowners keep yellowjackets at bay and enjoy their outdoor spaces without interruption.
