By the end of the summer, my legs are dotted with scars from the mosquito bites that I’ve furiously scratched. Yeah, it’s not a good look. Plus mosquitoes can carry diseases. I know I should cover up more or apply a personal insect repellent; I just get lazy.
While I’m careful not to leave standing water anywhere on my property, I can’t strong-arm my lackadaisical next-door neighbors to do the same—or remedy the standing water in the creek that borders my backyard. Hence, mosquitoes.
A few nearby residents looking for “mosquito control” hire pesticide companies to fog their yards. This spraying is known to be a futile, harmful and money-wasting endeavor. It’s also stressful for those of us nurturing wildlife gardens.
There are two critical points we all need to digest: 1) spraying is ineffective against controlling adult mosquitos and 2) spraying pyrethroid-based insecticides is harmful to all flying, hopping and crawling arthropods that come into contact with the product. Lightning bugs, moths, caterpillars, beetles, bees, butterflies, spiders… whether you find them repulsive or delightful, they are all at risk. Organically derived sprays can be just as lethal. If it kills mosquitoes, it does not discriminate.
The same is true for those bug-zappers. Two studies showed that only about 4 – 6% of the insects they electrocuted were mosquitoes while many other charred victims were beneficial. I only mention these devices because it’s been estimated that 1.75 million zappers are purchased annually in the United States. (Seriously, who’s buying these? I’d love to see the demographics.)
Should we even wage war on mosquitoes? If you rarely get bitten, then probably not. But if you do possess more mosquitoes than you can tolerate, it’s smarter to combat them without chemicals. Indisputably, the most effective mosquito controls are their natural predators. Nature itself is a mighty equalizer.
We habitat gardeners regularly enjoy a delirious amount of animal species that other olde-timey yard caretakers do not. For us, mosquito predators abound! These predators can be vertebrates and invertebrates: fascinating creatures such as hummingbirds, toads, salamanders, dragon- and damselflies as well as other insects and spiders (ahhh, here they are again).
Because I can’t stop mosquitos from breeding in every pocket of standing water in my immediate vicinity, what I aim to do is limit their numbers near my house. Anecdotally, my easy bucket-and-weed system appears to be effective and I’ve seen fewer mosquitoes since its implementation many years ago. It’s essentially a no-cost option that’s simple to construct. And it meets the objective of interrupting the mosquitoes’ lifecycle without harming other animals.
The trap, which I conveniently place near the backyard water spigot, lures in the egg-laying mosquitoes and prevents them from procreating in nearby unattended standing water. The American Mosquito Control Association writes, “Mosquito species preferring to breed around the house, like the Asian Tiger Mosquito, have limited flight ranges of about 300 feet.” That means I have a good chance of “trapping” some of these invasive pests.
I usually put the trap out when I see my first mosquito (which is typically May in Northern Virginia).
Here’s the recipe:
Place bucket trap in a shady area and commence monitoring:
If you’d rather be slightly more hands-off then you can peek into the trap weekly. Don’t forget, though! You don’t want to inadvertently make more bitey mosquitoes. However, daily monitoring is super fun! For me, anyway.
If you’re not going to be home for an extended period, just bring the emptied bucket inside.
There’s no need to spend money on dunks (larvicides) for this trapping method because you have full control of monitoring and changing the water once the eggs hatch (or even earlier, when they’re laid). For those places that are hard to reach or that have standing water too difficult to remove, dunks are necessary.
Because I roam about my garden daily, checking my trap becomes a habit. I’m out there cleaning out the critter water dishes and pulling out the weeds anyway. Besides, I find joy in experiencing the habitat I’ve created and seeing what’s a shakin’. It’s usually lots!
Maybe this brilliant bucket-and-weed method isn’t for you if you rarely wander outside? I invite you to investigate other types of homemade mosquito traps. There are also traps that are available commercially. You might even decide that dunks are the way to go… Anything but spraying, yes?
Just keep in mind that the objective is to break the mosquito’s lifecycle without affecting other living creatures.
