Any recommended Pesticide Sprays for yard that won't kill fish?

[MiPond]

I was thinking Permethrin since it is said to be a natural pesticide. My dad always used Tempo and claimed it was very safe for humans, not sure about fish?

Thanks for any advice. Mosquitoes are horrible this year due to wetlands nearby.

Why would you spray the garden, if the mozzies are coming from the wetlands?

Put the outside lights on at night early evening ,they attract the mozzies and other insects which intern attracts the bats which eat the insects and the mozzies.

Pesticides kill the good things as well as the bad things, but unfortunately chase the bird life out the garden.

Attract the birds with feeders.

They all help.

Permetherin ... which is i think a chemical match to something natural... is very toxic to fish and aquatic life..... plus bees. There is not reason to put down a chem to kill a lot of stuff just to keep mosquitoes from flying into your yard.

Try looking into the garlic sprays as a deterrent. The only smell like garlic for a few minutes but keeps the suckers away for a decent time. I assume rains effect it though. We spraying it at an outside wedding for my brother a day before and we had no one being up mosquitoes.. .even though they were really bad leading up to that day.

There are other non-tox items out there that use natural oils to deter things too you can try.

Permethrin is toxic to fish. Most pesticides that I'm familiar with are toxic to fish. My wife once used a systemic pesticide near the pond and after a very strong rain we lost nearly every small koi in the pond. The small ones are particularly vulnerable to pesticides.

Read and follow instructions TO A TEE when using any chemical. It is that simple. Use common sense when using chemicals around the pond. Study the wind, run off, and how you apply. All chemicals you can buy in the USA has to have a MSDS sheet (material safety data sheet) and you can access them on their website. That MSDS will give you all the information from accidental poisoning, exposure, and you will find out what LD50 (median lethal dose) is!

I use very toxic chemicals around ponds, and nature and have yet to make a mistake and accidently kill anything but the target pest.

What isnt toxic to koi? Probably could list it on one hand. Again let common sense prevail in working and spraying around the pond.

With the wetland producing large amounts of mosquitoes, I would focus on more of deterrent, than a poison. There will be an endless supply of skeeters flying into your yard. That's my opinion.

There are so many deterrent suggestions out there. From tiki torches, DEET, and a variety of natural smells.

When we sit on the deck, I use a oscillating fan that gently blows on us and that keeps the mosquitoes at bay. Zero bites

If you decide on using a chemical, no matter how toxic they are to your koi, used properly you will have no issues!
Good luck

Dynatraps on wall between pond and filter pit and at fence gates.

Use mosquito traps. Only IGRs are safe for fish and I don't think they can be used effectively outdoors or in water.

Thanks Everyone for the posts. I typically only spray select areas for ants and spiders, wife requires this of me. I have a grad party and want everyone to be comfortable since it has to be outside with this pandemic. I have heard great things about mesquito catchers and that willl probably be my long term option, but I doubt they will work in a pinch and quickly. My plan most likely will be a highbreed of chemical and deterrent. I'll follow the SDS for the pesticide and make sure im downwind when spraying anything. I would love to just be in harmony with the world and let it do its thing, but with Triple E and West nile being real threats in my area I feel its a necessary evil. Plus, one week after I spraying, everything will be back in my experience. I live in the woods pretty much and life finds a way here.

Check out NEEM oil. I have been using it around my pond with good results.

[MiPond]

I do have some neem oil for powdery mildew. I'll have to try that out.

CITRONELLA candles burning round the perimeter and these aerosol mozzies sprays should do the trick for an evening.

Will at least make it uncomfortable for the mozzies.

I was reading up on pesticides lately, kind of fell down the rabbit hole, and found this Paraquat FDA warning. Wild how something that’s been used for decades is now under fire for health risks that were barely talked about before. Makes you think twice about what we spray around, especially near water or where runoff can go anywhere it wants after a storm. Even stuff that’s legal and easy to buy isn’t always safe in the long run.

There is a bacteria - Bacillus Thuringiensis that stops mosquitoe larva hatching, and this can be applied directly to ponds, swamps, rainwater tanks etc.

I think its marketed as "Mosquitoe Bits" in America.

Wanted to participate in this thread necro with another vote for Mosquito Bits - If you live near wetlands, you can scatter these all over low places in your yard that may collect water when it rains a lot. Also they sell them in pressed donuts that you can chuck into any large body of standing water near your property - drainage ditches, wetlands, etc. Supposed to be completely non-toxic.

I use them in the saucers of my potted plants, have been for years, it helps a LOT.

I use it with new born fish fry! I culture green water and infusoria for first foods so mossie wrigglers get through occasionally.
