Innovative Mosquito Control Products

Cartoon "No Mosquito" sign

It’s officially summer, but most of us have been dealing with heat for quite some time already. And this means we’ve been dealing with mosquitoes for quite some time already as well. Luckily, there are more products than ever before that control these dangerous flying pests. They are, after all, the most dangerous animal in the world (here’s more on that). Here at ARBICO we have a great selection of highly-effective mosquito control products. Many of them are of the tried-and-true variety (personal repellents, sprays, zappers), which most people are familiar with, while others are the result of years (even decades) of creative thinking and innovative research and development. 

 - Bacillus thuringiensis israelensis (Bti) – 

A cartoon mosquito just hanging aroundBti is the OG of biological mosquito control. In 1976, Dr. Yoel Margalith (aka Mr. Mosquito) discovered Bti in samples from dying mosquitoes found in a pond in the Negev Desert of Israel. With further study, he determined that this naturally-occurring soil bacterium is deadly to mosquitoes when ingested but has no negative impact on non-target species and the environment (more on his work here). Bti causes mosquito larvae to stop feeding within one hour, followed by paralysis and death. This biocontrol can be applied directly to water (including drinking water), which makes it especially useful in a variety of circumstances from horse throughs to large-scale municipal water treatment facilities. We offer several different varieties of Bti, at a price point accessible to most anyone. If you have areas of standing water (large or small) that are your main mosquito-breeding locations, this is a no-fuss, no-worry product with a proven history of effectiveness. An added bonus: it is also effective against black flies and fungus gnats.

 - Bacillus sphaericus (Bs) – 

Bs is similar to Bti in that it contains spores that are toxic to mosquito larvae when ingested but is not harmful to other creatures or the environment. This is a selective larvicide and only works on certain types of mosquitoes; luckily these are some of the most common and deadly. It has several key differences from Bti: It is a selective larvicide; it cannot be used in drinking water; it works in highly organic aquatic environments (something Bti struggles with), and it persists where it is applied for longer periods of time than Bti. If you have a considerable area to treat and need that treatment to last as long as possible, this is an excellent choice for you. We have two exceptional Spheratax products that utilize this particular strain of Bacillus.

 - No-Bait Traps – 

The Enoz® Trap-N-Kill A-G-O Mosquito Trap and Skeet-O-Trap™ are traps that use a mosquito’s natural behaviors to lure them in instead of baits. They are designed to mimic the dark places with stagnant water that mosquitoes favor as a place to lay their eggs. Instead of baits, they use grass or hay clippings in water to get that stagnant water effect. The Skeet-O-Trap does not capture the adults; it only works to keep the larvae from escaping. The Enoz trap will kill both adults and larvae. Both traps are designed to work year after year and are effective against multiple mosquito species.A cartoon mosquito lying dead

 - SKEETER Mosquito Control – 

SKEETER Mosquito Control is brand new in 2022 and is no less than ground-breaking. It combines botanical oils (garlic and soybean) with nematodes (Heterorhabditis megidis) to provide quick and long-lasting control of larvae, pupae, and any young adults who may still be hanging around. The oils suffocate and kill on contact and the nematodes search out the larvae, enter their bodies, and release a bacterium into their bloodstream. This kills the larvae within 48 hours and the nematodes use the dead and dying larvae as a food source, which extends the efficacy of SKEETER to 30 days. The use of oils combined with nematodes makes for an exciting, and definitely innovative, product.

We are all familiar with the type of repellents that we apply to ourselves or to an outside area, but this type of repellent is a bit different. Bradshaw’s 4 Ring Protection Spatial Repellents form a dome of protection around an area using DEET-free botanical oils. Simply hang a pouch near the area you want to protect and the pleasant-smelling vapor it emits will draw the mosquitoes to it and away from where you want to be. It not only lures the mosquito, but it also interferes with their receptors so that they stop seeking a blood meal. This is not just an easy-to-use and cost-effective mosquito control product; it also lasts for days – considerably longer than other products. A cartoon of a mosquito's grave - his image is on the headstone.

 - Spinosad – 

Spinosad is nothing new in the world of pest control, but Natular® DT and Natular® G30 WSP bring it in a water-soluble form to control mosquito larvae. Natular DT is an effervescent tablet with an outer layer that dissolves quickly and begins killing immediately, but it also contains a layer that lasts 90 days for continued control. Natular G30 WSP comes in pouches with 10 grams of product in each. They last 30 days each in water but break down quickly in sun and soil. These are truly apply-and-forget forms of mosquito control.  

No matter which of these first-rate products fits your needs and wallet, you can be assured that it has the potential to keep summer-spoiling mosquitoes away.

Mosquito Deterrents

There’s just no getting around the fact that mosquitoes are more than nuisances – they’re dangerous and formidable opponents. We carry many excellent mosquito control products, but there are additional things one can do to improve their chances in the war between humans and mosquitoes. 

- BODY OINTMENTS - 
If you’re going to be out and about and know that mosquitoes will be a problem, you can begin your defense plan as soon as you get out of the shower. There are oils and lotions that are very helpful in repelling mosquitoes but choose carefully because some may actually be inviting bites.
A group of smiling cartoon mosquitoes. Certain essential oils, including lemon eucalyptus peppermint, lavender, geranium and citronella oil, have time-proven efficacy as repellents so apply them to your body generously. A secondary benefit of using these oils is the delightful scent that will surround you.  
Catnip oil is another oil to try. According to this article, the oil is extracted from the catnip plant via steam distillation, and the process eliminates the chemicals that make catnip irresistible to cats. The catnip plant is known to have a scent mosquitoes dislike, so it only makes sense that the distilled oil would be even more repellent to them.

For the most part, flowery perfumes and body lotions should be avoided. However, there is one strong exception to this rule: Avon’s Skin So Soft. Over many, many years millions of people have found this body oil to be an exceptional mosquito repellent. In fact, this product has been used by U.S. Marines as a mosquito repellent for more than 50 years on and around their training facility on Parris Island South Carolina. In the low country down there, mosquitoes are voracious, so these tough marines douse themselves in this sweet-smelling stuff. After all, it’s better to smell girly than be eaten alive.

You should be aware that the above types of oils do not have the long-lasting effect that many commercial mosquito repellents do. On average, they last about two hours.

 - CLOTHING - 
After you have carefully considered what to put on your bare body, put a little extra thought into what you wear (after all, you’ll look good in anything). 
Mosquitoes are attracted to the CO2 that mammals produce, but they also use their vision to zero in on a target. According to this article, as they fly characteristically slow and low to the ground, they respond to dark objects on the horizon. Which means you should probably choose a pastel as opposed to your favorite Goth outfit.
This study takes the whole color thing one step further. It finds that mosquitoes like red, orange, black and cyan and snub green, purple, blue and white.

Mosquitoes love the sweaty dirtiness of feet and there is very little as annoying as mosquito bites between your toes. For these reasons, skip the sandals and put some shoes on (even better, with socks).
While summer seems more bearable in cool and flowing clothing, if you are interested in doing everything you can to avoid mosquitoes than you need to don some tightly woven synthetic clothing (extra points for a high tech athletic wear made for sun protection). Mosquitoes may seem small, but their proboscises are rather large insect-wise and simply cannot fit through some of these fabrics. The downside is that  you’ll need to wear long sleeves and pants for optimal results, which may be a little too much coverage on a particularly hot day.

 - OUTSIDE SPACES - 
No one is able to control the whole outdoors, of course, but you should look at the outdoor space you can control – your backyard, patio, porch or balcony.
You probably already know that you should remove all standing water, but you may not be aware that mosquitoes only need a bottle-cap of water to lay their eggs in. It is also easy to overlook breeding spots like gutters, recycling bins, drains and saucers under plants. Instead of a quick once-over, give your outdoor space some careful

consideration to root out standing water.
Reconsider the plants in your space to make sure you don’t have any that are welcoming to mosquitoes. If you do, remove them and add plants that repel skeeters. Nectar-producing flowers and water plants are attractive to mosquitoes, while the plants that contain the aforementioned oils are excellent repellents (there are others too). 
Keep all your grasses cut down and remove any yard debris. Mosquitoes love to hide out in the relative safety of such places; it protects them from the elements – particularly sun and wind.

Speaking of wind, mosquitoes are poor flyers so put a fan in your outdoor space. If it is set high enough mosquitoes will not be able to fight the wind it produces in order to get to you

We are all familiar with the horde of insects beating against a porch or backdoor light, but a change of bulbs can element that behavior. Use incandescent or LED lighting, especially that which has a yellow glow, and you’ll see fewer mosquitoes and other flying insects.

Hopefully this has given you some ideas on how to lessen the effect of mosquitoes. All of these tips are valuable, but when used in conjunction with commercial mosquito control products you should see a marked improvement. If none of this works for you, you may just want to stay inside until the first frost kills the mosquitoes.

What's This Bug? The Shaggy-Legged Gallinipper.

Close-up of a Psorophora ciliata - The Shaggy-Legged GallinipperThese days everyone wants to just get out and get on with their summer fun (except for those of us in AZ who are entering our self-imposed, heat-avoiding annual lockdown); but, remember there are hungry creatures out there waiting anxiously for your return. Case in point: The Shaggy-Legged Gallinipper (SLG). If you think this sounds like something you might hear on a show like “Moonshiners”, you aren’t far off. “Gallinipper” is an heirloom Southern term for an exceptionally large insect with a frightening bite. Which this is and it has hairy legs.

Close-up of a Shaggy-Legged Gallinipper mosquito sitting on a finger.So, what is this bug? It's a mosquito (Psorophora ciliata), but not your average skeeter. It’s unusual in many ways. First of all, the SLG is big (as you’ve no doubt deduced) – like 3 to 6 times as big as a typical mosquito. It’s fairly rare and does not appear unless there has been abundant wet weather. It’s also an aggressive carnivorous predator that prefers other mosquitoes as prey, but does not limit itself to them. On the up side, it’s not a vector for disease transmission to humans.

A map showing in gray the areas where the Shaggy-Legged Gallinippers can be found in North America.
SLG Distribution  
The SLG is a mosquito that is hard to miss and hard to forget. At about the size of a quarter, you will see these suckers coming. While their size may be intimidating, they are not the largest mosquito in the world. That honorific belongs to the genus Toxorhynchites and can be found worldwide. Toxorhynchites mosquitoes are huge, but at least they are not bloodsuckers. More on them here.

A flooded meadow with more water in than foreground and more green in the background.Although their territory is expanding as our climate changes, the SLG is primarily found in the Southeastern and Midwestern parts of the US. That being said, they have been reported as far north as Ontario and as far south as Argentina. Even though recent severe hurricanes and flooding have been followed by a rise in the SLG population, these are still uncommon mosquitoes. Everything has to fall into place for them to emerge in numbers, This is due to how they have adapted their lifecycle to respond to flooding events. SLG females have the ability to hold sperm until they find an ideal egg-laying time and location. They then fertilize the eggs as they are being laid and create an egg bank (which can contain a million eggs) for future hatching. For an SLG mom the perfect spot is not in standing water like many mosquitoes, it is on moist and low-lying ground that will likely flood at some point. This means they could be in anything from a drainage ditch to a woodland meadow. There the eggs will sit for as long as it takes for water to reach and cover them, then they will hatch. This waiting period can be years-long long, but the eggs are specially adapted to remain viable when dry and can easily overwinter. Once a hurricane or some sustained thunderstorms bring water to them, all these patient eggs will burst out all at once and the race will be on to start the next generation.

 Due to the transient nature of the pools from which the SLG emerges, these mosquitoes have a short eggs-to-adults period at just over a week. The adults then only live for a couple of weeks. Both of these are factors in why they grow so large and ferocious. They first grow big in their larval stage when they are eager carnivores, dining on other mosquito larvae and other aquatic invertebrates, and size matters when it comes to the ability to capture and consume prey. Likewise, being bigger and stronger for their short lives means that they can produce more eggs or sperm and do not need to feed to bulk up. Females may only need one full blood meal to get the nutrition she needs, which reduces the likelihood that she will seek out a human to bite and also puts her out of the disease-transmission game. However, by all accounts, you don’t want to get bit even once by one of these. It has been reported that their bite feels like a stabbing and is strong enough to go through two layers of cotton.

A black and white cartoon of people reading a large screen that says>< "Giant Mosquitoes Advancing On City"Here at ARBICO, we have some fabulous mosquito control options to arm yourself with before heading out there this summer. However, if you live in certain areas that are prone to flooding and/or hurricanes and still hope to be out enjoying nature in the coming months, be aware that you may get nailed by a large and strong lady mosquito. But, she’ll probably only bite once. Of course, she has billions of sisters that she hangs out with, so……

What’s This Bug? The Crane Fly.

Adult Crane FlyHere in Tucson, we are in the middle of Crane Fly season and it's creeping people out all over the city. These gangly insects are everywhere – and I mean everywhere; I even found a dead one in my purse. This phenomenon happens every year, but the numbers are greater when the area experiences wet weather late in the previous year. This was the case for our city in late 2019 and into early 2020. Crane Fly larvae grows best in damp soil and the accumulated rain triggered growth in wildflowers and grasses, which provided a stable food source for the root-eating larvae. With all that organic matter to feast on, the larvae population grew and thrived. Which leads us to this moment, when large numbers of adults have grown from that larvae and are now out looking for mates.
Insects swarming a light

A side-by-side of a Mosquito (on the left) and a Crane Fly (on the right)People around here have to run a gauntlet of  these quivering critters to get through their front doors. Like many other insects, Crane Flies are attracted to light; so avoiding these clusters can be tricky. You can turn off the light by your door, but they will still see the light leaking out from inside. So, unless you turn all your lights off, you will probably just have to deal with them and wait them out - they will only be around a couple of weeks.


Crane Flies must be one of the most wrongly identified insects out there. They are most commonly mistaken for mosquitoes, and for many people they spark a sort of primal fear of that particular insect. But, Crane Flies are not mutant mosquitoes plotting to suck you dry of blood. They are not mosquitoes at all or even closely related –they are members of the fly family (Tipulidae spp.) and only share a passing resemblance to mosquitoes.

Crane Fly on a yellow flowerIt is not only misidentification that plagues Crane Flies, but widespread misunderstanding of their capabilities and motivations in life. Hence the Mosquito-eating monikers like “Mosquito Hawk”. Crane Flies do not, despite the deepest desires of some people, eat mosquitoes. In fact, they do not have the mouth parts to eat anything (or bite – more on that in a minute). Some have a visible proboscis, which some scientists say they use to suck up flower nectar. Other scientists dispute this feeding claim and believe they do not eat at all as adults and survive by living off the fat stores accumulated in their larval stage. Lending credence to the not-eating, energy-conserving hypothesis is their activity level; they don’t fly around endlessly. They sort of bump-jump-fly and then find a spot to cling to.

Because they do not have the proper mouth parts or stingers, Crane Flies are harmless to people. They cannot (so will not) bite, sting or suck on people. For all these reasons, they also do not carry diseases. Their Daddy-Long-Legs-combined-with-mosquito looks and their twitchy movements may give you the willies, but they pose no danger.

Life stages of a Crane Fly, from the 1st instar on the left through 2nd and 3rd. The adult stage is the last on the right.While adult Crane Flies are completely harmless, the same cannot necessarily be said for their voracious larval form (which is 95% of their lives). Crane Fly larvae are great decomposers; they consume all sorts of organic material in the soil. However, they will not discriminate between unwanted organic matter and desirable plant roots. So, for those in search of the perfect lawn, they can be seen as a problem. Keeping your lawn healthy will discourage excessive feeding (check out our lawn products here) and treating the area with beneficial nematodes (we recommend NemAttack™ Steinernema feltiaeshould keep their numbers down. For more on controlling Crane Fly larvae, read this article.

A hand holding a huge insect - the giant-sized Chinese Crane flyIf you are still convinced that the current Crane Fly situation in Tucson is horrific, consider what it must be like in the Sichuan province of China. Back in 2017, outside the city of Chengdu, a monster-sized Crane Fly was captured. It has since been confirmed to be the world’s largest.

Here's a video for more general information on Crane Flies.

Adult Crane Flies may be aesthetically challenged, but they serve a purpose beyond their own reproduction. They are a bounty to insect-loving animals in our environment. Birds, bats, lizards and other wildlife are currently having their own version of Thanksgiving over-eating. I can envision them in their homes, contentedly sleeping off their feast – just like Uncle Fred on the couch after too much turkey.
