Natural Mosquito Prevention INSTEAD of Spraying!

Mar 11, 2013

OK PEOPLE, Dallas is planning to increase it's aerial spraying program this year. I find this not only unwarranted but reprehensible. The chemicals they will yet again be raining down upon us are not necessary...if they'd just focus on prevention. But see this mosquito problem is one that we the people can get control of ourselves, if we just put forth the tiniest effort. All it takes is a few handfuls of a natrial larvicide to do the job. And guess what? Now's the time you need to be planning for prevetion. While we've had a few cold snaps, we've also had a lot of warm days. The Fleas are already hatched out and jumping. Mosquitoes won't be far behind.


Bt (Bacillius thuriengensis var. israelensis) also known as Thuricide (liquid form) or Mosquito Bits, is my not so secret weapon to having no mosquito problems in my yard. This naturally occuring bacteria is fatal only to larvae and caterpillars. The species included in this product is particularly effective against Mosqutio larvae (and fungus gnats). All you have to do is sprinkle a few handfuls of the bits under your foundation shrubs, any landscape beds with automated irrigation or that you water regularly, drain boxes, low spots in the yard and even gutters. I do this about three times per year. Timing depends on the weather. If it's warm early, I'll put out my first application in April, if it's not then early May. Then again in June and July. If you have ponds, birdbaths or live on a creek, purchase the floating dunk form and just pitch one, or a piece of one in the standing water.

The Bt attacks the Mosquito larvae and kills them before they even have a chance to hatch. This bacteria is safe for children, pets, birds and fish. It's the most non-toxic and most effective treatment for dealing with Mosqitoes (Hello, Dallas?)

Quit over-watering your lawns and quit watering them over-night. Highland Park, Preston Hollow and Park are major culprits. I know this, because I've personally inspected many of your irrigation systems...I know how much and how often you're watering. That's why you have so many fungal problems and decline in your St. Augustine and on all those Indian Hawthornes and Azaleas. I'm not saying it's all your fault..but realize many of you have maintenance companies that are setting your irrigation improperly.  If you need help figuring out how much and when to water, please drop me a line! But, I know plenty of you Lakewood and East Dallas Hipster residents that are just as over-generous with your watering. So no one is off the hook here!

If neighbors, or neighborhoods, got together on prevention we could make a huge dent in the city's Mosqiuto population. Make a deal with your neighbors...if you live on a creek, each one of you should get together and buy a 4 or 6 pack of the mosquito dunks. Once per month from April or May - July or August, just pitch one out the back door into the creek. You'll be AMAZED at the results! Do you have a housebound or elderly neighbor? How about buying a pack for them and dropping it off, or better yet, apply the bits or dunks in their yard/creek for them?

See that big jug in the photo?  (from Summit Chemical btw) It will cost you around $12-$13 bucks. Maybe less. Last summer I used about 20%-25% of the container and saw about 3 mosquitoes total on my property. Seriously people, why leave this in the hands of the city when they will only spend way too much of our money on an ineffective and toxic treatment? Spend a few bucks, knock on your neighbor's door, and let's prevent this problem before it even gets started...

I operate a news service for N TX called Moonlady News. May I run your blog entry above on my site please? I will append your bio and contact info to it. I’d also like to get it circulated among the neighborhood associations in my area.

Hi Leslie,

I enjoyed this post alot, and would also like to share it on my blog and with our neighborhood association (Casa View Haven).  Your idea of sharing this news, as well as helping out with our elderly neighbors, really appeals to me and everyone around here has creeks, viaducts, and the usual suspects (clogged gutters, badly drained areas, and some empty yards with furniture and tires collecting water) that require this kind of application.

No one is thrilled about the aerial sprayings and yet no one has made a concerted effort to organize and take charge.  I think, like you do, it’s not rocket science… it just takes getting everyone on board.  I am sick of getting eaten up by mosquitoes in our yard and subsequently worrying I am developing a headache… a flu symptom…. holy cow, it’s enough to drive one batty.  Anyway, good work on keepig the promise to yourself and good luck in your new situation.  best, chris

Hi Leslie,

I was sharing this information with some neighbors and the question came up regarding whether BT is harmful to butterfly larvae. I presume that you would never advocate for this product if it were not specifically targeted to mosquito larvae. Do you have any more info on BT, such as a web address to an FAQ or something?

Thanks so much, I enjoy looking at your blog and shopping NHG smile

Hi Bonne,
Bt will kill butterfly larvae IF they come in contact with it and consume it. This is rare when you apply Bt in bits or dunks form, as they get applied to either standing water or low spots that collect tiny pools of water. This is not where you find butterfly larvae. Now, if you you were to spray the liquid form of Bt on your garden (veg garden) to say kill cabbage loopers, then yes, if beneficial larvae consumed it they would also be killed. This is why you don’t spray your dill, fennel rue, etc. with Bt. But again, it’s rare that the pelleted form you put out for mosquito larvae would contact many if any of your butterfly larvae. Make sense?

Bt is the abbreviation for the bacteria Bacillius thuriengensis. Trade names for the product are usually Thuricide (liquid) and Mosquito bits or dunks. Just google any of those names and you’ll get lots of info.

BTW - I left North Haven Gardens back in December. I run Halleck Horticultural full time now!
