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.


I’m looking for some natural products I can use for controlling mosquitoes around my house. I keep an organic garden and don’t want to use anything synthetic or toxic. I’ve heard there are some new sprays which are all natural and safe and work well but I couldn’t find them on your side. Do you know of any or can you make any recommendations?

In recent years a few all natural products have come to market that do indeed work well for mosquitoes. Our biggest seller is the ECO IC. Made from plant extracts this product is safe to use around organic gardens and is highly effective on mosquitoes and other flying nuisance pests. Apply it with one of our Fogging Machines as explained in our Mosquito Control article and you should be able to get the desired results you want.


I want to do some mosquito spraying and was wondering what you’d recommend. It’s a small area, about 2500 square feet so I don’t think I need a lot of spray but something that will last more than a day wold be nice.

If you read through our Mosquito Control article you’ll see that we have products that can be sprayed as well as fogged in the yard. Generally spraying should be limited to small yards. We consider a yard smaller than 3000 sq/ft to be small so I’m pretty sure spraying would be an option for you. Most people should consider getting a fogger when yards are 5000 sq/ft or more but I think you’ll be able to get good results by spraying alone.

In our article you’ll see we have Esfenvalerate which can be applied in a Hose End Sprayer making it easy to apply and use throughout mosquito season. Add some Nylar to the mix if you want the treatments to last a little longer. Generally these treatments will last 1-2 weeks but with the Nylar, they could last a month or two. The key will be getting good coverage and treating once a week for 2-3 weeks to insure you break their cycle. Once this cycle is broken keeping them under control will require a lot less treating and should be manageable.


I’ve got asian tiger mosquitoes in my yard and they’re active most every day. Will your products work for them? Can I spray during the day and get good results?

Many species of mosquitoes will be active during the day. Though most are nocturnal or night time feeders, there are some that make a living by the light of the sun. Asian Tiger Mosquitoes will start to forage by mid morning and many times will be most active mid day. This is especially true during cloudy or overcast days. Since they prefer the protection of shade, cloudy days allow them to forage most anywhere meaning it’s harder to hide from them in open sunlit areas of the yard.

If your primary concern is the asian tiger mosquito, we recommend treating with the products in our MOSQUITO CONTROL ARTICLE early in the day. Typically the plants and vegetation will have a lot of moisture and dew which enhances the applications and allows for good transfer and coverage. As the Asian Tiger emerges it will be consumed and you should get great results. Most all of our mosquito products will dry quickly after being applied and all will be equally effective on this species compared to others.


I’m looking for something I can spray around a damp and shady area on the back side of my house that’s non-toxic but will kill mosquitoes. They get really bad where we like to sit and the citronella candles don’t seem to do much anymore. Is there anything I can use that won’t poison my yard or family?

First of all, any of the products we have listed in our MOSQUITO CONTROL article won’t poison people or the yard if used correctly. There is no need to over apply them and since mosquitoes are easy to kill, little product is needed so you can get control without putting undue risk to anyone or animal in the area.

Secondly, in this same article you’ll see we have ECO IC listed which is an all natural, food derivative concentrate that can be sprayed on anything and providing good control for various pests including mosquitoes. You can apply it as a liquid using a SPRAYER or one of the FOGGERS listed in the article. For small areas, spraying it once a week will keep them under control. Fogging is better suited if you have 2500 sq/ft or more and want to use less chemical and time over the course of a summer when treating a lot.

I have a small fish pond which most of the time doesn’t have any fish. It’s not that I don’t like fish; I have tried to keep them and for awhile I was doing quite well. The problem has been that some local animal seems to like them too. He has been sneaking into my yard and eating all the fish so for now, I’ve given up trying to keep any. I’ll probably try again but for now, I’m letting it go. That’s when I noticed another problem.

Since I don’t have any fish in the water, there are thousands of mosquito larvae swimming around and I’ve noticed a huge surge in the local population around my house. I know I can’t control all of them but I don’t think breeding them in this water is smart either. Is there something I can apply to the water that won’t poison it for the fish?

Mosquito larvacide comes in many forms. We have a natural form which won’t hurt fish, birds or anything and is quite easy to apply. Known as MOSQUITO DUNKS, this product is both easy to use and effective. You’ll need to apply some at least once a month but they do work and should be able to reduce the larvae quite a bit if not completely.

Alternatively you can opt for a growth regulator like ALTOSID METHOPRENE. These granules use a chemical which prevent the larvae from being able to grow completely so their growth cycle will be effectively shortened and no biting adults will ever emerge. This product is very easy to use and very effective.

Ultimately you might opt for one of the mosquito treatment options listed in our MOSQUITO CONTROL article if you wish to get rid of them in the yard. Since they can come from so many sources, it’s many times impossible to get them all when only treating one location. That being said, I highly recommend you start with this pond since it’s such a bad problem anyway.


I live in a damp moist river bottom where mosquitoes seem to thrive. I’ve read that fogging for mosquitoes is quite effective and I’m thinking about getting a machine that can handle about 1/2 acre. Do I need to get the backpack fogger or will one of your electric models do the job?

This is really a matter of preference. No doubt one of our medium sized foggers like the FM6208 or the FM6309 would do the job. But you will have to drag the power cord around the yard as you work. I don’t know the lay of your land so it’s hard for me to judge if this will be a problem or not. Our BACKPACK FOGGER is much easier to use and over time would save time and energy so it might be worth the extra start up costs. We have other models which can be seen in our MOSQUITO FOGGING CONROL page.

Fogging for mosquitoes is an effective way to control local populations. I have learned that once they’re under control I only have to fog every 10-14 days and if it remains dry like it’s been in the Southeast for the past two years, I can go 3 weeks in between treatments. Besides saving a lot of time, I’m able to treat the same area with a lot less chemical so in the long run, fogging is a good way to treat your home for most any pest.


We have a bad problem with tiger mosquitoes in our yard and my kids are getting bites on the legs. What do you recommend I can put on them to treat the sore?

Asian Tiger Mosquitoes are active most of the day and can be a nuisance. Their bite not only itches but it can swell and be uncomfortable even if it’s not itchy. We have two ointments that we’ve found have worked well over the years at treating mosquito bites. The STING RELIEF SWABS are the preferred option for adults but they work great on anyone. STINGER STOPPER seems to be more acceptable by kids. It’s distinct yellow color seems to make them more tolerant of having it applied and less likely that they’ll rub it off since it’s highly visible. Both do a great job at relieving the discomfort.

Ultimately, you should consider doing some mosquito control around the property to reduce local numbers. We have several ways to treat this pest which are very effective and carefully explained in our on line MOSQUITO CONTROL article.



We have several concentrates that could work for your situation. Based on the size of the sprayer you have, I would say the ESFENVALERATE would be a good option. It only needs a little bit to go long way when treating the turf for  mosquitoes. We also have some other “spray” options that can be seen in our MOSQUITO CONTROL article on line. My only concern is that spraying such a large area will take some time. Furthermore, it will not be as efficient compared to fogging.

I strongly recommend you read through our article to see the other options. Once you learn about other treatment options – specifically fogging – I think you might consider getting a fogger to do the work. Fogging is very effective, much easier to do and uses a lot less chemical over time. I can treat my 1/2 acre yard in 5-10 minutes using our BACK PACK FOGGER. It’s very efficient and totally portable. And it saves on chemical usage as well. But it’s not the only fogger that can do the job; we have several featured in our MOSQUITO FOGGING section.


I’ve got lots of standing water on my property and I’m hoping you’ve got something I can use to kill them before they become biting adults. My property has drainage ditches and several low points that don’t drain. With all this rain we’ve been getting I know they’ve been laying eggs in several of these pools because I can see them swimming around. The humidity has been so high I just don’t think the areas will dry out enough to kill them so I want to do something if I can. What can I use?

There are two or three products that can be applied to standing water which work well. It’s not clear how big of an area you want to treat but for small pools, the MOSQUITO DUNKS or MOSQUITO GRANULES would work well. Both use BT as the active and are considered to be organic so they’re very safe. They can actually be used in rain barrels used to collect drinking water.

There is also a chemical growth regulator that you can get in our METHOPRENE GRANULES. This is very effective and cost efficient too. Either product should help and we have other options listed in our MOSQUITO CONTROL article.


It seems like there are a lot of mosquitoes nesting in my grass. I water it a lot since I use well water and I notice when I go out there mosquitoes are everywhere. I thought they need water like a pond or lake to breed but now I’m thinking they might be living in the grass. Is this possible?

Absolutely. There are several mosquitoes that commonly lay eggs above lakes or ponds. There are others that lay eggs on the ground. The key is that most all do need some amount of water but the amount produced by watering your grass just once a week could be enough. If you are watering 2 or more times a week, there definitely is enough to allow several of the species listed in our MOSQUITO CONTROL ARTICLE to both live and reproduce in your grass.

If you suspect this is the problem area, you’ll need to either spray or fog as explained in our article to get the infestation under control. Mosquitoes breeding in these open areas can be controlled with the right coverage so be sure to treat all your grass and mulch in order to reach their nests. MOSQUITO SPRAYING can be done efficiently if the yard is fairly small. For any yard 1/2 acre or larger, you’ll do a much better job doing some MOSQUITO FOGGING. It just uses chemicals more efficiently and over time will save both time and money. That being said, both options are very productive on mosquitoes.


I have read your amazing site and it seems you have all bases covered if I want to treat for mosquitos. Problem is I can’t decide what would be best for me!! Is there a simple answer for someone that has .5 to .75 of an acre? About half the yard is open and the other half is filled with ground cover like ivy and shrubs. I know I won’t be able to control all the mosquitos in the neighborhood but if I can just be able to go outside and not get eaten (or my dogs for that matter) I would be happy. Any help here would be appreciated.

Sorry for the confusion; there are a lot of options and it just gets more confusing all the time with new products coming and going. Fortunately for our customers we do all the “leg work” to find out which ones are best suited for their situation. Based on the information you sent us listed above, here is what I would recommend.

I have a yard similar to what you’re describing. I use the BACK PACK FOGGER with nothing but BIFEN in it and I only have to fog once every 2 weeks. It controls everything from mosquitos to ants to roaches to gnats. I could probably treat even less frequently but because we’ve been getting so much rain (and I live on a big river), there is a lot of bug pressure so I don’t want to give them a chance to get established. Over the years twice a month applications seem to keep them at bay whether it’s dry or wet so that’s the routine I stick to and I never have a problem.

Do you have to get a Back Pack Fogger to do this work? Definitely not. For me, it just saves so much time and works so well, it has paid for itself over the years for sure. It only takes me 10-12 minutes to do the entire property and I’m even spraying every side of my house which is almost 50 feet tall in some areas. The point I’m making is that I’m able to walk freely, misting and blowing my yard clean, as I treat it for all kinds of bugs. One of our ELECTRIC FOGGERS would do the same thing but it would take longer for you to get the job done. Spraying would take even longer and over time, you’d probably not keep it up like you will fogging. Additionally, the foggers use almost half as much chemical and get so much better coverage that again, you’ll get better results with less effort and chemical.

One other thing worth mentioning. In the past year, we started selling a food grade fogging compound known as ECO IC which has turned out to work quite well too. It won’t last as long and I’m not sure you’ll be able to go 2 weeks between treatments but we have been selling it for two years and it works for sure. If you are at all hesitant about using the Bifen, the ECO would be a great alternative option that does in fact work well. Hope this helps!


I have a small yard with grass that seems to have a mosquito problem. I also have an organic garden right along side my yard and don’t want to use any pesticides so close. Do you have anything organic I can spray that won’t be toxic to my garden?

There are now several organic sprays you could use for such an area. The most popular would be the MOSQUITO KILLER RTS. It simply hooks to your garden hose, the turn dial is turned on and the water flowing through the hose will use the compound to treat the grass without you having to mix anything. Mosquito Killer uses Pyrethrin and Soap as the active and is NOP certified and compliant so it’s Ok for use around organic gardens. You should be able to keep any flying pest under control with this material. And be sure to check out our other organic products all of which can be seen at NON TOXIC PEST CONTROL.


I’ve been seeing mosquitoes in my lawn and it looks like they’re nesting in the grass. Is this possible? I do water the lawn every other night but i thought they needed water to breed?

They do need water to breed but it doesn’t have to be standing water like a lake or pond. In fact, the water which accumulates in the lawn following a good rain or water sprinkle cycle can many times be enough to make them happy. First they’ll move in for shelter and if the good conditions persist, they’ll start reproducing for sure.

Mosquito lawn treatment is easy since the area is wide open and usually accessible. We’ve got many methods detailed in our MOSQUITO CONTROL ARTICLE including liquid spraying and fogging. ESFENVALERATE works well, is easy to apply and covers a large area. If you prefer something organic, go with the MOSQUITO KILLER RTS. It won’t last as long as the Esfenvalerate but it does work and it comes with it’s own hose end sprayer. Be sure to treat any ground cover which may be harboring mosquitoes as well. Mosquitoes will flock to anything moist and many species only need a drop of water to survive so there are a lot of plants which can serve as fertile areas for them to reproduce.

If you have a large area to treat, you’ll find one of the Fogging solutions mentioned in our artilce will prove to be more effective and efficient for lawn treating. In the long run, you’ll use a lot less chemical and save a bunch of time as well. Fogging will work on the structure, in the lawn or on any plant growth as well.
