The simple:

For Mosquito control, I keep it simple. I fill a container with water, put a small piece of Mosquito Dunks per container. Place the container under a bush or another shaded location where you want to kill mosquitos. It is that simple to effectively kill the mosquito population around that bucket! But there is more to it for preventing mosquitos throughout your property.

From the manufacturer

• Kills Mosquito Larvae Before They're Old Enough To Bite

• Organic Lasts Up To 30 Days

• Each Dunk covers 100 square feet of surface area

• The only product with BTI, a bacteria toxic only to mosquito larvae. Non-toxic to all other wildlife, pets, fish, and humans

All the details:

If you go online you can find directions for concocting a mixture that creates carbon dioxide to attract mosquitos....I don't waste any time with that, I just use tap water. When fighting mosquitos, one of the first things to do is remove any standing water on the property. Instead, I use that standing water to my advantage. When I first started out I used any containers I had handy, basically all out of the recycle bin. They were so small though they would evaporate and dry up, but they did work. Now I primarily use paint cans. They are big enough to hold enough water to not dry out in the summer and collect rain. I use clean water to fill, but it doesn’t matter if it gets dirty.

I fill the paint can's 3/4 with water, use about 1/8 of a tablet per can, even that is overkill for this size container. Then I spread them out. Mosquitos are very localized. I can beat mosquitos around my pool, walk 50 feet to a shaded corner of the house where the hose bib is and get bit. So I have probably more then 15 cans spread around the yard where I spend time and then on the perimeter of the yard. I keep the cans under bushes in the shade where I know mosquitos would want to breed. If I encounter a mosquito it means I probably need to reapply the dunks or adjust my can locations/quantity.

The side benefit is the spider population. I used to have spiders everywhere. I did nothing to control them and as soon as I deployed this mosquito control method, the spiders disappeared. Not all species, but some, like the wolf spider and fishing spider. This method was over-night impactful on mosquito population (couple days for full control) and was massively impactful on the spider population. Either the spiders were eating the mosquitos or eating something else that was eating mosquitos. Either way, the spiders decided they had better places to be. This does not directly control spiders, it just gets rid of mosquitos which discourages the spiders.

I don't tolerate a single mosquito at my place, they are huge mosquitos with painful bites. This solution is a scalpel, not hurting anything but mosquitos and it is cheap and easy to deploy.  Compared to $100+ per month chemical spraying service that probably kills all kinds of insects, this method is a miracle for me. I wish I had discovered it a decade ago. And that's why I am quick to offer the solution to people. About $25 for a 20 pack which lasts multiple summers and a little upkeep on the buckets once a month. Slam dunk (pun intended) that gave me my yard back!

Hope it helps!
