The Mosquito Sentry is the only large area non-toxic mosquito repellent available that provides continuous protection while on. It is placed in the center of your outdoor gathering and produces a non-toxic vapor of plant compounds that repel mosquitoes. In optimal conditions of medium to high humidity and little or no wind, it can protect up to 15 people in an area 30' x 30'. It has a 1.5 gallon tank that will last for 20 hours. You turn it on only when you are outside. It is safe for people, pets and food. Please note that it is not suitable for indoors, even tents, or for large crowds of people.

Unlike mosquito traps which attract and kill mosquitoes and other biting insects, the Mosquito Sentry keeps them away from you.  You place it near you to protect the area you inhabit outdoors.  You can also put it near open doorways to protect a building. If you have moderate to heavy mosquito density, you should also get one or more traps.  

The advantages of the Mosquito Sentry? It is inexpensive to operate for the coverage it provides, about $2.00 per hour for the repellent. It does not release even minimal toxicity and uses no flame.  It is very compact, has no objectionable odor, and has nothing to monitor or clean.

How the Mosquito Sentry Works

The Mosquito Sentry requires no assembly, installation or maintenance. You plug it in, fill the tank, and turn it on either at the machine or by the included remote control. It has a count-down timer to show the amount of repellent remaining in the tank, and a warning light when the repellent is getting low. It automatically shuts off when empty.

The dual vapor outlets are at the top of the machine. The vapor is composed of sub-micron particles that are not noticeable. They do not make your skin feel damp, and apart from a slight floral odor, will not be perceived at all.

The Mosquito Sentry is totally Green - no insecticides/no DEET. Mosquito Sentry Repellent is 100% natural and “green,” and is made from plant oils that are exempt from EPA registration. In addition, the FDA has declared that the ingredients are safe and even acceptable as food additives. Furthermore, independent toxicity lab tests confirm that these plant oils are safe in all aspects for humans and pets: skin, oral, eyes, dermal, and inhalation. As a result, your family and pets are not exposed to any harsh or potentially dangerous insecticides, unlike almost all other repellents.

The compounds used in the Mosquito Sentry have been proven effective by both field and university testing. The repellent material is significantly more effective than Deet (used in Off!) and Citronella, the two most widely used repellents in the world.

Repellents are good for light to moderate mosquito activity.  One Sentry will protect up to 15 people in a 30' x 30' area under medium to hight humidity and little or no wind. More people will overwhelm the vapor and windy or very dry conditions will not allow the vapor to distribute as widely. For larger areas or more people, you may need more of these, mosquito traps or both.

If your outdoor area is more than a small patio or the mosquitoes are moderate to heavy, you should also get one or more traps. See our recommendation page. 


One of the main components of the Mosquito Sentry Repellent is Geraniol. The letter below describes tests of the substance vs. Deet and natural oil products:

We live in northwest Minnesota on the River. We have of course had a good deal of problems with mosquitoes in our yard and on our deck. As Hearty Minnesotans, we can and do deal with the issue of mosquitoes, using chemicals that I've always worried may not be good for our health.

Now, we have grandchildren and we are blessed that they live nearby and can visit us regularly. The problem was that we have one grandchild who is very allergic to bug bites and mosquitoes (especially mosquitoes and gnats) and we were desperate to find something that would work for him that was natural. When we found the Mosquito Sentry we were elated!

This device is completely natural and works like a miracle. We place the device on our back deck, turn it on, and within minutes the bugs are gone! Needless to say our little grandsons are now able to enjoy their wading pool, sandbox and dinner on the deck without getting bitten by mosquitoes and gnats! We don't have to worry that we are exposing them to dangerous chemicals!

The Mosquito sentry is a real miracle for our family! Thank you L. T.

We have a pool and my husband and I both work. We swim after work with the kids, at dusk, the worse time for mosquitoes.

The first time we used our Mosquito Sentry it was incredible. We had all those mosquitoes swarming us over the pool and thought we would have to get out like all the other nights.

I told my kids that I got this new mosquito repellent machine and turned it on. Within a minute there were no more mosquitoes!!!

Our family got to enjoy our evening in the pool without the typical dusk run into the house so we wouldn't get bitten. We love the Mosquito Sentry. H.G.
