Mosquito-Proof Your Patio

A patio with outdoor seating surrounded by flowers

Picture your backyard oasis: a shady spot to read, the birds are serenading you from the branches, and butterflies are flitting amongst the flowers. Now imagine your peaceful reverie quickly unravels by the whining of a mosquito in your ear.

Have you ever stopped to think about where that mosquito came from before it disrupted your serenity? Chances are it emerged from somewhere much closer than you would suspect.

Toss The Saucers

That beautiful potted plant your mother-in-law gave you might be the culprit if it’s sitting in a saucer full of water. Saucers provide the perfect dark, wet environment for Asian tiger mosquitoes to lay their eggs that are barely visible to the naked eye.

Once laid, the eggs simply lie in wait for a good watering and can hatch within just one day. One week later, 50 hungry mosquitoes will emerge, ready to pester you.

Consider switching out your traditional saucers for plant stands, pot trivets, or pot feet.

These alternatives provide the following benefits:

  • Allow water to drain away from plant roots, preventing soggy feet and eventual root rot

  • Less likely to stain your deck because they don’t stay wet and have a reduced footprint

  • Discourage fire ants from nesting underneath pots due to increased air circulation

  • Come in a variety of materials, sizes, and colors

  • Don’t breed mosquitoes!

A Donut in Every Bird Bath

After a mosquito lays eggs in your plant saucer, she’ll lay more in your birdbath, kids’ toys, and forgotten containers. While toy trucks and buckets can be picked up, drained, and put away, the birdbath is one place where we actually want water to sit for a few days. Our feathered friends appreciate a clean place to splash around, so take a moment to spruce it up, give it a good scrub, and dislodge any dirt and mosquito eggs.

After you’ve cleaned your birdbath, keep it mosquito-free with a Mosquito Dunk®, a biofriendly, cheap, and easy solution that is harmless to birds, pets, people and fish. One donut can treat a 100-square-foot area, so it can treat your bird bath with a single dunk or less. Read the back of the package for portion suggestions and use only the amount needed for smaller areas.

If you have a rain barrel or other means of capturing rainwater, go ahead a put a dunk in there, too. The active ingredient, Bti, is certified by OMRI for use in organic gardening.

A Big Fan

A large oscillating or box fan is a powerful tool when it comes to mosquito-proofing. Overhead fans are nice, but they don’t combat mosquitoes. A fan that blows air horizontally creates an air current too stiff for mosquitoes to handle; their flight speed maxes out at two miles per hour. A gentle breeze is about ten mph, so the larger the fan, the greater the area you can keep mosquito-free.

Get your mind in the gutter

It’s easy to forget about your gutters – out of sight, out of mind. Unfortunately, just a few leaves and needles can clog it up, creating a dark, wet environment for mosquitoes to thrive. After rain, it only takes a week to hatch a whole new crop of biters above your front door. Regular gutter maintenance won’t be the most exciting thing to do with your weekend, but you can delight in all the mosquitoes that you are evicting from your eaves.

Do you have a French drain?

Called by many different names – blind drains, rock drains, perimeter drains – these are underground trenches with perforated pipe that are meant to redirect water. However, they tend to perform far better at breeding mosquitoes than alleviating your drainage situation.

If you do have a French drain, keep it mosquito-free with a Mosquito Dunk®. Tip:  keep the dunk from washing away by tying it to the drain cover. Ensure the string is long enough so the donut can rest on the bottom of the catch basin. The naturally occurring bacteria in the dunk can survive multiple wet and dry cycles, so if you can see it in there, it’s working. Expect to tie on a new dunk about every 30 days.

Guard with garlic

Garlic barrier, commonly sold as Mosquito barrier, has been used for years in agriculture to repel insects from crops, and even to keep birds from eating tree fruits. Dilute this liquid garlic concentrate with water and then apply it with a pump sprayer to plants and structures around the perimeter of your yard. One application lasts about a month, but it needs to be reapplied after rain. This can be a great tool to use ahead of a pool party or family barbeque – after you’ve tossed anything holding water!

Benjamin Franklin famously noted, “Nothing is certain, except death and taxes.”  In Southeast Texas, you can add mosquitoes to that list. What you may not have known is that you have more control over mosquitoes – at least the ones in your yard – than you think.
