I set up four traps in my back yard each one has the exact same bait but each one is a different size. The bait that I used for my mosquito traps is dog chow that was fermented for a few days.
The first trap that I set up was a small plastic water bottle cut in half then I placed the bait, then the wooden stick but the first trap was a complete failure since my dog ate everything inside the plastic water bottle.
For the second trap I used a bigger water bottle this was half a gallon and I put it in a place where my dog could not get it but when I checked back on this trap a week later and It got infested with ants instead of mosquitoes.
The third Trap was a gallon and was put In a similar place as the last trap this one was not infested with ants. Since I am traveling in Mexico I have not been able to check on my mosquito traps that I set up back in my AOI at home but so far I have not seen any mosquito larvae.
The fourth one was the biggest trap yet this one was a wheel barrel set up in my back yard in this one I have not found any larvae as of right now but I will check back on it when I come back from Mexico.
Here is a picture of the second trap (this picture was taken when I was setting up the trap I put In the wooden stick after the picture was taken.)
Conclusion: when I get or while I am here in Mexico I will set up more traps with a different bait since dog chow isn’t the best option.
update 7/21/2022: I have returned from my traveling and I went to checked back on my traps to find that only one of the traps had a successful result.
The trap that had worked was the biggest one, the fourth trap that I set up, as demonstrated in this image here.
As you can see the water looks disgusting but a least there seems to be a lot of mosquito leave, in this picture you can see at least more that 30.
So in conclusion dog chow is a successful bait especially when applied to large containers.
