Mosquito - Newsletter Update 2011
Mosquito Control Doesn't Have to be Dangerous.
Here's the update on our recommended program:
1. Empty standing water where possible. Even small containers such as pot saucers, old tires, soda bottles and cans hold enough water for mosquito breeding.
2. Treat water that cannot be emptied with gambusia fish or (Bti - Bacillus thuringiensis ‘Israelensis’) products such as Bactimos Briquettes or Mosquito Dunks.
3. Spray to kill adult mosquitoes with "essential oil" plant oil pesticides such as Avenger Natural Insect Control or EcoSMART. Garlic oil sprays work well to repel the insects for up to 20 days. Even better, broadcast dry garlic to the site at 1 - 2 pounds per 1000 square feet. Dr. T’s Mosquito Repellent is another good dry product but Bonide Mosquito Beater Granules are more cost effective and work better.
4. Use organic landscape management to encourage birds, bats, fish, dragonflies and other beneficial insects.
5. Use skin repellents that contain natural repellent herbs such as aloe vera, eucalyptus, tea tree oil, lavender, vanilla, citronella and other helpful herbs, but avoid the dangerous DEET products.
Commercial Mosquito Control
Besides being a summer nuisance, mosquitoes pose some public health problems, carrying such deadly agents as malaria, yellow fever and West Nile virus. However, conventional pesticide application is often less than effective in controlling mosquito larvae before they hatch and repeated use of toxic materials has raised various environmental and health concerns.
West Nile Virus is the most overblown health threat since the “killer bees.” Yes, people have gotten sick and some have even died from West Nile Virus, but people need to put things into perspective. Very few have died from West Nile Virus while thousands die annually from asthma and other respiratory diseases.
Be aware of what your city is spraying for mosquitoes. Toxic spraying does more harm than good. Cities across the country have been foolish and have listened to the chemical pushers under the misconception that spraying toxic chemicals is helpful in controlling the mosquitoes. Spraying toxic chemical pesticides, known generically as synthetic pyrethroids, has been the primary recommendation. Besides being toxic, this procedure doesn’t work. An adult mosquito spray program conducted late at night, as is usually done, misses the primary activity time of the pests. It also sprays or fogs down streets primarily affecting front yards of residential property. Most mosquito problems are in back yards. When these airborne toxins reach water features, ponds and creeks, a common result is the death of fish including goldfish and koi.
The risk of getting West Nile virus is remote. A very small percentage of mosquitoes have the virus, an even smaller percentage of people exposed to the virus develop symptoms and a minute percentage of those people even get sick. Spraying toxic chemicals for the control of mosquitoes is a waste of money and an unnecessary assault on people, pets and the environment – plus it simply doesn’t work. There are very few adult mosquitoes flying around early in the morning when the spraying is done plus there is good argument that the spraying actually increases the mosquito problem by killing beneficial insects such as dragonflies that help control mosquitoes.
Synthetic pyrethroids like Scourge (resmethrin) are particularly hard on people with asthma and other allergies. These toxic products now contain piperonyl butoxide (PBO), a synthetic synergist that interferes with the insect’s system of neutralizing toxins. PBO makes the pesticide more effective at killing the targeted pest, but the override of the body’s detox system is also a concern for all other animals including birds, lizards, toads, frogs, beneficial insects, pets and humans. MSDS sheets (Material Safety Data Sheets) on these products from the pesticide manufactures point out that liver tumor increases in test animals has been significant. Of course, they claim that humans aren’t in danger.
Rational, effective control of mosquitoes results from removing or treating stagnant water with biological products, horticultural oils or gambusia fish and wearing non-toxic repellents on the skin.
If spraying the air to try to repel or kill adult biting mosquitoes is required, there are highly effective non-toxic alternatives, such as several brands of essential oil products.
Cinnamon oil kills mosquitoes
Cinnamon oil shows promise as a great-smelling, environmentally friendly pesticide, with the ability to kill mosquito larvae, according to a new study published in the July 14 issue of the Journal of Agricultural and Food Chemistry. The researchers also expect that cinnamon oil could be a good mosquito repellant.
Vanilla home remedy:
