I’ve got a small back yard and need to do some mosquito control. It seems they’re everywhere now that it’s been raining again and it’s warm. I’ve read through your article but can’t decide if I should spray or fog. My yard is just under 5000 square feet and I’m only concerned about the back. The front is wide open with no plants or shade and we never seem to see mosquitoes there anyway. What should I do?

If you don’t have any standing water, the two options which would work well for your problem would be either spraying with a hose end sprayer or fogging with one of the small machines we have listed in our Mosquito Control article. Based on the size of your yard, either would work well. The difference would be in the cost when compared over time.

Since spraying takes more time and uses more chemical, it basically costs more to do on a regular basis. That being said, it doesn’t require the high cost of any special equipment to get started so it will cost less to do initially (less chemical and equipment investment money needed). But if you expect to be in the house for a few more years, getting an electric fogger that is used over this time period will provide enough of a savings to more than pay for itself. In the end, the fogging machine saves so much time and chemical that it makes sense to get when treating yards which are 5000 sq/ft or more.

Additionally, the fog does a much better job of covering all the plants and vegetation compared to a liquid spray. If you have a lot of plant growth, mosquitoes will be able to hide and avoid the liquid. This is not so easily accomplished with the fogging process.


I’ve had an ongoing battle with mosquitoes that are nesting or living in the ivy I have growing in my back yard. There is a lot of it and most is pretty thick too. Some is draped over a fence and some is on the ground. I estimate we have 3-4 thousand sq/ft and I’m wondering if the liquid treatments you have would be best because it’s so thick or if fogging would be a better solution?

Ground ivy is one of the best hiding locations for mosquitoes. Ivy can hold moisture well and provide all the ingredients needed to let mosquitoes both reproduce and stalk food.

Treating ivy is mostly dictated by where it is growing and how much of an area you need to treat. Based on what you listed above, you should be able to get good control using just a liquid concentrate that’s sprayed out with one of our Hose End Sprayers. If the ivy is on the side of a hill making it difficult to access, one of our Foggers might be the better option. You can see several models that could handle this task in our Mosquito Control Article.

Minimizing moisture in these areas could help a lot too so try and keep water to a minimum as this will certainly attract more to the area. Using Nylar with the tank mix will improve any performance of the treatment so be sure to include some to help reduce retreatments.
