mosquito larvicide

[Iron Brew]

We have water where we never have had before, and the mosquitos are coming. Hard. Wondering if anybody has tips, and if they can tell me where to get some larvicide.

this is standing ground water, not trapped in man made objects...

Us too. But we would like something that doesn't kill dragonflys. Once they are up and running in 3 weeks they can keep the skeeters under control but right now - OMG!!!

[Iron Brew]

The areas I'm talking about haven't had water in 10 years. Do dragonfly eggs last like Mosquitos?

Goldfish or minnows?

This should work as well:

Sounds like this could be the ticket!

These guys are talking about rain barrels! I talking about acres and acres of ponds!

[Iron Brew]

I'm not quite talking acres, but I do have a bunch of smaller "ponds" that will dry up, but not before they hatch bazillions of little bloodsuckers...

Sorry to "warm up" an old thread.
Did anybody try those mosquito dunks? Do they work?
Really save for pets?

Mosquitos and dragonflies don't inhabit the same waters. Ponds do not contain Mosquitos.

Mosquito habitat is intermittent flooded areas like ditches. Some ponds may have some intermittent water around the edges. Intermittent sloughs or very shallow intermittent marches can also hold mosquito larvae.

Mosquitoes lay eggs just above the water line. Eggs can be viable for a very long time. During large rain events...multiple egg generations can hatch at once.

If you have limited water away from pets a home remedy is just enough canola oil to leave a nice film. The larvae can't push their breathing tube up to get air and suffocate.

Permanent water contains too many natural predators. Don't waste the larvacide on the wrong water.

Look for products with BTI in the listing.This will attack most mosquitoes ,but only mosquitoes and some black flys.Bti produces toxins which are effective in killing various species of mosquitoes Commercial formulations include "Mosquito Dunks"/"Mosquito Bits". It is also available in bulk liquid or granular formulations for commercial and public agency use.Check with your County Field Man for advice and sources.

I bought one a few months ago, and never set it up, because I didn't think it would work, was I wrong.

It attracts the females and puts then all in a little screened box. Switch boxes and let the sun dry out the bugs. Repeat as necessary.

It knocks the heck out of the population with the females gone. Hard to believe but it works better than anything I have ever tried.

It can run on a battery but a plug in and a propane bottle and you are in business.

That's great info. Thanks! We do have some standing water around that are not ponds. Do you spray canola oil on it? How much do I need? Is that going to be a problem for other insects, birds etc?

Does it really work? I saw the dunks but wasn't sure if they work. We tried the garlic spray this year and it didn't work at all! We also tried the Mozi-Q pills and again it doesn't help at all.

Do your own test by putting some larvae in a bowl with a few drops of canola. Generally you want a healthy sheen. Just enough they can't break the surface tension.

Sneak up on the water. You should see the larvae drop to the bottom. Pour some oil there.

It can smell as the oil degrades so don't let dogs run into it.

Not great for large area but buy bulk cooking oil and give it a try.


I should warn you that it will likely do little good as mosquitoes can move in from nearby area. You should just consider an adult mosquito trap.
