Testimonial research by Dr. Joel R. Coats of Iowa State University:
The following are the professional opinions provided by Dr. Joel R. Coats, Ph.D., a senior professor of Entomology and Toxicology at Iowa State University.
“I am a Professor of Entomology and Toxicology at Iowa State University, in the department of Entomology. I have served on the faculty here since 1978. My areas of expertise include natural insect repellents and natural insecticides. The original efficacy data received from Scientific Information Inc. in Gainesville, Florida demonstrates that insect repellant bands have efficacy in the field. The results prove that a slow-release delivery of volatile essential oil can afford protection from mosquitos via a spatial repellency. The mode of action of volatile essential oils from plants is to repel mosquitoes by vapor action – released from the oils. Peppermint oil releases menthol; and oil of citronella releases geraniol and citronellal. The band represents the best possible delivery for monoterpene [these types of gases] so that protection can be provided over substantial time. Our chamber tests indicated that the band generated a statistically significant spatial repellency over time.”
“The bands are impregnated with the repellent mint oil, which is quite evenly distributed into the plastic, and diffuses out of the plastic steadily but slowly. It will certainly provide mosquito-repellant activity for at least five days (120 hours). The emitted amount of the impregnated mint oil will slowly decreases over time, like any simple diffusion process.”
“Since the bands consist of very lipophilic plastic, they do not absorb water. The repellent oil can also not be rinsed out of the plastic by water.”
The professional opinions of Dr. Coats are a testament to the effectiveness of the Bug Band.
Tick and Mosquito Repellent Can Be Made Commercially from Pine Oil
By Sharon Durham
A patent (US 7,378,557 B1) was issued on May 27 for the compound, isolongifolenone, and partners are being sought to bring this technology to commercial production.
In laboratory tests, ARS chemist Aijun Zhang in theInvasive Insect Biocontrol and Behavior Laboratory, Beltsville, Md., and his colleagues discovered that the naturally occurring compound deters the biting of mosquitoes more effectively than the widely used synthetic chemical repellent DEET. The compound also repelled two kinds of ticks as effectively as DEET.
Insect repellents are used widely to prevent bites from mosquitoes, sand flies, ticks and other arthropods. For the most part, people apply repellents just to avoid discomfort, but there is a more serious side to the use of these products. Human diseases caused by blood-feeding ticks and mosquitoes represent a serious threat to public health worldwide.
Malaria is the chief threat, killing approximately two million people per year and threatening billions. Other diseases include dengue fever, chikungunya, Lyme disease and typhus. Some segments of the public perceive efficient synthetic active ingredients as somehow more dangerous than botanical compounds, giving additional importance to the discovery of plant-based isolongifolenone.
Zhang’s team also developed an easy and efficient method to prepare this repellent. Many natural-product chemicals isolated from plants and essential oils have proven to have repellent effects. Most often, such compounds never attain commercial development and their use is limited or impractical because they are expensive and not available in pure and large quantities.
In contrast, this newly-discovered repellent can be prepared inexpensively from pine oil feedstock in ton quantities for large-scale commercial applications, giving it a significant advantage over many of the other natural-product repellent chemicals.

West Nile Virus
What Is West Nile Virus, and what does it mean to consumers?
“The easiest and best way to avoid WNV is to prevent mosquito bites.” -Centre for the Division of Vector-Borne Infectious Diseases.
Most often, WNV is spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Infected mosquitoes can then spread WNV to humans and other animals when they bite.
People over 50 at higher risk to get severe illness. People over the age of 50 are more likely to develop serious symptoms of WNV if they do get sick and should take special care to avoid mosquito bites.
Being outside means you’re at risk. The more time you’re outdoors, the more time you could be bitten by an infected mosquito. Pay attention to avoiding mosquito bites if you spend a lot of time outside, either working or playing.
There is no cure for WNV – symptoms will either pass on their own, or those with severe cases may suffer death.
Eastern Equine Encephalitis Virus (EEEV)
Eastern equine encephalitis (EEE) is a mosquito-borne viral disease. EEE virus (EEEV) occurs in the eastern half of the United States where it causes disease in humans, horses, and some bird species. Because of the high mortality rate, EEE is regarded as one of the most serious mosquito-borne diseases in the United States right now.
EEEV is transmitted to humans through the bite of an infected mosquito. It generally takes from 3 to 10 days to develop symptoms of EEE after being bitten by an infected mosquito.
Many persons infected with EEEV have no apparent illness. In those persons who do develop illness, symptoms range from mild flu-like illness to inflammation of the brain, coma and death. The mortality rate from EEE is approximately one-third, making it one of the most deadly mosquito-borne diseases in the United States. There is no specific treatment for EEE; optimal medical care includes hospitalization and supportive care.
Current cases of EEE in the United States have pushed EEE into the league of concern for which WNV was previously dominant. Mosquito bite prevention has become one of the leading concerns in health care in North America.
