Wasps, much like hummingbirds, are attracted to sweet, sugary liquids. The sugar water in your hummingbird feeder is a high-energy food source for wasps, particularly in warmer months when their natural food sources are limited. Additionally, wasps are territorial, often defending their food sources aggressively, which can scare away hummingbirds. Understanding this behavior is the first step in preventing wasps from dominating your hummingbird feeders.
According to studies from the National Wildlife Federation, wasps’ reliance on sugary foods increases in late summer as they prepare for winter. Knowing this can help you tailor your strategy for wasp prevention during these months.
1. Choose the Right Feeder
The design of your feeder can play a significant role in keeping wasps away. Experts at the Cornell Lab of Ornithology suggest choosing feeders with bee and wasp guards, which are small mesh coverings that allow hummingbirds to feed while preventing insects from accessing the nectar.
Additionally, saucer-style feeders—where the nectar is stored below the feeding ports—make it harder for wasps to access the sugar water. Research has shown that feeders with smaller feeding ports, designed specifically for hummingbirds, can significantly reduce wasp presence.
2. Move the Feeder Regularly
Wasps are creatures of habit. Once they discover a food source, they return frequently. By moving your feeder every few days, you can confuse wasps and reduce their visits. Entomologists recommend placing the feeder in shaded areas, as wasps prefer sunny locations. Hummingbirds will have no problem locating the feeder, but the wasps may give up after a few failed attempts.
3. Use a Wasp Trap
Using a decoy or trap is another effective method for controlling wasp activity. You can purchase commercial wasp traps or make a DIY version using a plastic bottle and sugary water. According to PestWorld.org, placing these traps at least 10-20 feet away from your hummingbird feeder will draw wasps away from your birds’ feeding area.
However, be cautious when setting traps, as they may attract more wasps if placed too close to the feeder.
4. Keep the Area Clean
Wasps are attracted to spilled nectar and sugar water. Regularly clean your feeder and the area around it to reduce wasp attraction. The American Horticultural Society recommends washing your feeder with a mixture of water and vinegar every few days to keep it sanitary and less appealing to insects. Overfilling the feeder can also lead to spills that attract wasps, so be sure to fill it just enough to meet your hummingbirds’ needs.
5. Use Non-Toxic Repellents
Non-toxic repellents like essential oils can be an effective, environmentally friendly solution. Research from the University of California’s Integrated Pest Management Program suggests that peppermint oil disrupts wasp behavior and can serve as a natural deterrent. Mix a few drops of peppermint or eucalyptus oil with water and spray it around the feeder area. Be careful to avoid spraying directly on the feeder, as it could deter hummingbirds as well.
6. Minimize Yellow Decorations
Wasps are particularly drawn to the color yellow. If your feeder has yellow parts, consider switching to one with red or orange accents, as these colors are more attractive to hummingbirds but less so to wasps. You can also place yellow sticky traps at a distance from the feeder to lure wasps away.
7. Adjust the Nectar Recipe
Hummingbirds thrive on a 4:1 water-to-sugar ratio, but wasps prefer a stronger concentration of sugar. Adjusting the nectar to a slightly diluted 5:1 ratio can make the feeder less attractive to wasps without impacting the hummingbirds. The Smithsonian Migratory Bird Center recommends this approach for regions with persistent wasp problems.
8. Remove Nearby Wasp Nests
If you’re dealing with a large wasp population, you may need to address the root of the problem by removing nearby nests. Professional pest control experts recommend locating and removing wasp nests to reduce the number of wasps visiting your feeder. Always consult a professional for nest removal to ensure it’s done safely.
Conclusion
Keeping wasps away from your hummingbird feeder can be a manageable task with the right strategies. By choosing the appropriate feeder, using traps, keeping the area clean, and employing natural deterrents, you can enjoy watching hummingbirds feed without interference from wasps. With these expert-backed tips, your garden can remain a peaceful haven for hummingbirds while keeping wasps at bay.
