People spreading coqui

[missydog1]

Rob, I was told this week by the main guy at Garden Exchange that some nurseries already implement citric acid in the automatic sprinkling/irrigation.

He said it runs citric acid solution, then maybe 15-30 minutes later it runs a rinse cycle. This because citric acid will burn plants. (some, not all).

For humans -- citric acid is an eye irritant. Put lemon juice in eye, get an idea. It stings.

The problem with citric acid use in the yard is that the coqui like to sit in leaf curl and other protected spots on the plant. The citric acid has to be a certain strength to kill them and it has to make direct contact with the frog.

That's why the nurseries advise to hose down plants 15 minutes after spraying, because the citric acid is not going to kill them with residue. Either they are dead already or you missed them, so then rinse the plants so they aren't burned.

I like the way citric acid isn't a white powder all over like lime and the way it stays mixed up and potent.

right now I am trying ammonia (pure household) in a Windex sprayer for the frogs that are "under the window." My neighbor swears it works. I haven't captured a frog and observed it die. If anyone else has, please confirm.

As soon as the ammonia hits, the frogs hop away fast, so that's why I haven't verified that ammonia makes them maki.

Good idea on the perimeter mist spray system, Rob! Making it easy to keep the perimeters clear would go a long ways towards being able to sleep at night, I would think. Also, on hot days, you could use it as a yard cooling off system. Wonder if it would work with in-ground systems? Or build a trap that the frogs would go to and then sprinkle that area? Any way which uses less people power to kill the coqui is a good method as far as I can see.

as I listen to my little coqui frogs outside I read your ideas and I have to tell ya the frogs win. Don't waste your time.
I have had them swim in wet cement and hop off.
They will live anywhere not just in the trees. They love wood piles.
Last year I even cleared a lawntractor path around the perimiter of the property so I could put around pulling the sprayer. Got all the equiptment, (which anyone can have if they want it) and spent enough energy to learn,
The frogs win.
They sound like crickets in the swamp.
And they are no where as near a pain to listen to at night as the idiot with the bzzzz boom boom bzzzzzzz bumm bumm bzzzz bmm bmm bzzzzzzzzzzzzz bmmmm bmmmmm

The citric acid burns alot of exotics and lime and baking soda only if they go sit in it might it kill them. We have sprayed thousands of gallons and the first time was 3-4 years ago,

But don't take my word for it, spray.

Rob, make sure everyone in misting range has goggles on 8) Or put it on a timer or light sensor so it mists at night. With a barometer so it won't mist on rainy nights?
