Call your local health department ... they will fill it in and bill the owners For now, toss some mosquito dunks in there.

@flyngeorgiabelle, You need to call the Minister of the Environment. There are strict rules about applying this stuff and if the company is breaking any of them the MOE will warn them. Mosquitobuzz.com has a policy that if neighbours complain enough they will cut and run. They know this stuff is not the gentle flower-based product they claim to neighbours. We filmed them spray directly into our yard, I wrote an email detailing that they had sprayed me bodily when I was trying to get them to stop (five years later I have possible thyroid cancer and am waiting for surgery) and they sprayed on windy days allowing the product to waft into our windows. If they are doing those things you have a good case. Get video of it if you can (safely from a window inside.) The rules the MOE told me about are: they cannot spray on windy days, they cannot spray in the presence of humans, they must wear masks and protective clothing when spraying, they have to post a sign after spraying. They are also not supposed to spray anywhere near water sources since this stuff kills fish. It also kills bees and other pollinators. And cats - it is toxic to cats. Don't let your cats outside to eat grass that has been sprayed - one of ours developed a tumour in his stomach and had to be put down. This stuff is not supposed to be sprayed around children because it can seriously harm them. The company is in my opinion seriously evil for telling all of us it is an "all natural product made from crushed flowers." Crysanthemums are toxic to cats. Every product on Earth is "all natural" Agent Orange is 'all natural' that does not mean it isn't harmful. Please take care of yourself and stay away from this stuff. Ask the MOE to give you the product sheet on it. If you get sprayed, remove your clothing and put it in a ziplock - that is evidence in case you want to take things further legally. (I didn't know that until later). The good news is that if you complain enough the MOE will call them and they will stop spraying. OUr neighbours hired a different company the next year, and we took video of the guy spraying without a mask and the MOE shut them down. Our neighbours did not get a refund for that so they stopped hiring them. Thank goodness. OUr woods and animals and water sources are the better for it. The bees and monarchs are still few and far between though. Good luck and reach out if you have more questions. I have a fact sheet somewhere...Also - the company will tell you they have switched to a garlic spray (or it has been a garlic spray all along) after you complain. Garlic is also toxic to cats.

Mosquitos grow in water. Fruit flies grow in trash. If you take away the food source (garbage/old fruit), they will be gone soon. They don't live very long and you won't get a fresh batch without the food. [Young mosquitos are wiggly wormy things that must be in water. They're like butterflies: most of their life they are caterpillars (this stage is underwater in mosquitos), then they go through a chrysalis stage (also underwater in mosquitos), and they only fly when they are full grown adults.]

I just adore how those products gleefully list all of the many pests that they control….but don’t add all of the non-target arthropods that are killed, too. Say goodby to bees, ladybugs, butterflies, bees, and beneficial predatory insects. OOPS, Martin , are you the Martin who answers questions on that site? Sorry, gotta flag spammers.
