The warm weather is here to stay! With the warm weather, cook outs and spending time outdoors will most certainly be on your agenda. Unfortunately, at some point your outdoor activities may be ruined by pesky mosquitoes. Unfortunately, much of what the general public believes about mosquitoes and mosquito control is not accurate. It has been garnered from the Internet, discussions with neighbors, or from stories passed down between generations. This article will address some of these myths and fallacies, explain why they are not true.  

1. Mosquitoes Come From Damp Vegetation. The mosquito life cycle requires water for the egg, larval and pupal stage. Adult mosquitoes, when not flying or biting, prefer to rest in areas that are cool, dark, moist and out of the wind. One of their favorite resting sites is vegetation, so customers may think that this is where the mosquitoes are actually breeding because that is where they are most likely to encounter them. You should direct your adult mosquito control efforts to sites, whether residential or commercial, that are cool, dark, moist and out of the wind. Partly True.

2. Mosquitoes Live the Entire Summer. Although the life span can vary by species, most female mosquitoes live 2-3 weeks. It is highly dependent on environmental conditions, particularly temperature and humidity. Also, some species that spend the winter months as adults may live six months or longer. False.

3. Certain Plants Are Highly Effective At Controlling/Repelling Mosquitoes. There are no plants that are effective at repelling or controlling mosquitoes simply by growing in a yard or in landscaping. What they do provide, however, is nice harborage for mosquitoes and other pests to lurk in. Many plants contain essential oils that may repel insects, but the plants must be crushed or burned for this to happen. False.

4. All Mosquitoes Bite Humans. First, only the female bites. She does so because she requires a blood meal to produce her eggs. After just one blood meal, a female mosquito can produce about 250 eggs. Some feed on large mammals, others on birds, and some feed on reptiles and amphibians. False.

5. Fans are Ineffective in Repelling Mosquitoes. Mosquitoes are delicate creatures and relatively weak fliers, a floor fan or two on their deck or patio to help to keep them away. Ceiling fans, which are often kept on a low setting, are not very effective, as mosquitoes tend to stay relatively close to the ground and hence don’t feel any breeze. False.

6. Trimmed Vegetation will Help Reduce Mosquitoes. As stated earlier, mosquitoes prefer to rest in places that are cool, dark, moist and out of the wind. Thick vegetation can provide all of this, and therefore is an excellent harborage for mosquitoes to hang out in. Trimmed vegetation allows for more airflow, increased sunlight, and generally drier conditions, all of which will serve to discourage pests. So, encourage your customers to keep vegetation neatly trimmed and not touching houses, garages, and other structures, if feasible. True.

7. ‘Bug Zappers’ are Effective at Controlling Mosquitoes. Black light insect electrocution devices are very popular with homeowners, who enjoy sitting outside at night and hearing the “pop, zap and pow” as bugs are vaporized. However, according to the American Mosquito Control Association, in two published studies, mosquitoes comprised only 4.1% and 6.4% of the daily catch over an entire season. In addition, the zappers also killed a large number of non-pest insects, including many that are beneficial predators on other insects. So, zappers do, in fact, kill some mosquitoes, but they certainly do not control them.False.

8. Mosquitoes are Just Pests and Serve No Earthly Good. Mosquitoes are an important component of the food chain. Mosquito larvae and pupae are eaten by fish (and occasionally by other organisms) and adult mosquitoes are eaten by bats, birds and other insects. And, believe it or not, there are some mosquitoes that eat other mosquitoes in the larval stage! False.

9. Some People are Bitten More Often by Mosquitoes Than Others. I can’t tell you how many times I have heard conversations go: “When my husband and I sit outside, I get bitten all the time, but he never does.” The No. 1 thing that mosquitoes use to find a host is carbon dioxide, which they can sense from quite a distance. As they get closer, they also key in on heat. Once a mosquito gets real close to a potential host, things get complicated. A variety of odors, including sweat, lactic acid, perfumes, shampoos and others are detected by a mosquito’s highly sensitive antennae, greatly influencing biting behavior. Visual factors, such as host movement, may also play a part. So, many things come in to play to help a mosquito decide who she is going to bite!! I like to explain it by saying that each of us puts out a unique “chemical signature,” some of which are more attractive to mosquitoes than others, and these “signatures” are highly variable and influenced by many factors. What can safely be said, however, is that there is no scientific evidence to support the claims that ingesting things such as garlic, vitamin B12, bananas, and beer either attracts or repels mosquitoes. True.

10. Bats are Effective at Controlling Mosquitoes. It is a widespread belief that bats eat thousands of mosquitoes every night. Far from it. Food items identified in the diets of bats are primarily beetles, wasps and moths. In fact, according to the AMCA, in all studies to date, mosquitoes have comprised less than 1% of the gut contents of wild-caught bats. There is no question that bats WILL eat mosquitoes but their use alone will not be effective in controlling them. False.

11. All Mosquitoes Bite During Dusk and Evening Hours. This is one of the biggest misconceptions. Several mosquito species, most notably the Asian tiger mosquito, will readily bite during daytime hours. Additionally, they are “secretive’ biters,” often focusing their efforts around the knees and ankles so customers are not as likely to see them. False.

12. Mosquitoes All Fly About the Same Distances. Depending on the species, the flight range can be very different. Some species, such as the Asian tiger mosquito, only fly about 100 yards from the breeding site. Most species will fly about 1-3 miles but saltmarsh mosquitoes may fly up to 40 miles! False.

Clearly, there is a lot of misinformation floating around about mosquitoes and what works to control and repel them.
