Mosquitoes have spread West Nile virus over most of the United States in just four years. If your like me,... worried about protecting my family from the little bloodsuckers that carry malaria, encephalitis and other diseases, you want a bug spray that is effective and does not have adverse side effects.  This website is dedicated to a collection of information from my research of bug sprays or as their known by the regulating officials "insect repellents". There are several methods to minimize your family's risk from mosquitoes in the Control & Protection section. I will start out with the two main products that research shows are the highest effective products.  See the Repellent Comparison page for a break down of other products. I do not endorse any particular product or method but would like to provide the information that I have found helpful to my family.

Bite Blocker

Made From 
Soybeans, Coconuts & Geraniums

DEET was developed by the U.S. Government in 1946 and produced in the 1960's.  It was approved by EPA in 1957.  Higher concentrations (20-30%) provide protection from 6 to 8 hours.

Bite Blocker provides an all natural blend of plant oils that offer protection from 4 to 8 hours.  It has been available in the U.S. since 1996.  The ingredients are listed by EPA as minimum risk ingredients and most are food grade.

Products contaning DEET are beneficial as insect repellents, but have been associated with dermal and neurological reactions in humans.  The use of DEET concentrations greater than 30% increases exposure and risk of adverse reaction with little or no benefit in protection.

(Cornell University)

Bite Blocker provided 97% protection over a three and a half hour period in comparison to a 6.65% DEET product which provided 86% protection over the same period.

Products with lower concentrations of DEET are not necessarily safer for children than those with higher concentrations.  Therefore, the EPA no longer allows claims that (DEET) products are specifically indicated for children.

(American Academy of Pediatrics)

Bite Blocker can be used safely on young children.   As published in the New England Journal of Medicine (July 2002), Bite Blocker For Kids provided better protection than the DEET based product for Kids with 5% concentration.

Sunscreen effectiveness is dramatically reduced when applied at the same time with DEET.

(Consumer Specialty Products Assoc.)

Sunscreen nor the effect of the insect repellency is degraded when Bite Blocker is used with inorganic sunscreen ingredients (i.e. Zinc Oxide, Titanium Dioxide).

A combination of chemicals (DEET, permethrin, and pyridostigmine bromide) given to protect soldiers against deadly diseases and nerve gas may cause damage to reproduction organs according to experiments at Duke University Medical Center published 1/8/03.

www.dukemednews.duke.edu

No known combination side effects
Avoid contact with plastics (eg. watch crystals, eyeglass frames), rayon, spandex, and painted or varnished surfaces due to the damage DEET causes to these.  Never apply DEET over cuts, wounds, and inflamed, irritated skin.  Avoid water activities since DEET washes off easily leaving you unprotected.

Pesticides: Topical & Chemical Fact Sheets   Reregistration of the Insect Repellent DEET

April 28, 1998

 

  1. What is DEET?
  2. What recent decision did EPA make concerning the use of DEET?
  3. How is EPA changing cosmetic claims on DEET product labels?
  4. Why is EPA changing child safety claims on DEET product labels?
  5. What should consumers do in the event of a potential reaction to DEET?
  6. What benefits do DEET products offer?

 


1. What is DEET?

DEET (chemical name, N,N-diethyl-meta-toluamide) is the active ingredient in many insect repellent products. It is used to repel biting pests such as mosquitoes and ticks, including ticks that may carry Lyme disease. Every year, approximately one-third of the U.S. population is expected to use DEET. Products containing DEET currently are available to the public in a variety of liquids, lotions, sprays, and impregnated materials (e.g., wrist bands). Formulations registered for direct application to human skin contain from 4 to 100% DEET. Except for a few veterinary uses, DEET is registered for use by consumers, and it is not used on food.

DEET is designed for direct application to human skin to repel insects, rather than kill them. After it was developed by the U.S. Army in 1946, DEET was registered for use by the general public in 1957. Approximately 230 products containing DEET are currently registered with EPA by about 70 different companies.

What is RED? EPA evaluates existing pesticides that originally were registered when the standards for government approval were less stringent. This comprehensive evaluation and risk mitigation process is complete when EPA is satisfied that the pesticide(s), used in accordance with approved labeling, will not pose unreasonable risks to human health or the enviroment. EPA's regulatory conclusoin about each case is presented in a document called a Reregistration Eligibility Decision (RED). Later, once product-specific data and revised labeling are submitted to EPA and approved, the Agency reregisters products containing the eligible pesticide(s). A pesticide product is not reregistered, however, until all of its active ingredients are eligible for registration.

 

 

2. What recent decision did EPA make concerning the use of DEET?

EPA recently issued a Reregistration Eligibility Decision (RED) for the chemical DEET. After completing a comprehensive re- assessment of DEET, EPA concluded that, as long as consumers follow label directions and take proper precautions, insect repellents containing DEET do not present a health concern. Human exposure is expected to be brief, and long-term exposure is not expected. Based on extensive toxicity testing, the Agency believes that the normal use of DEET does not present a health concern to the general population.

Most of the changes to DEET registrations required by EPA concern label directions and claims. The Agency also is encouraging companies to provide a company telephone number or toll-free number on all product labels for consumers to call for additional product information and to report incidents. The Agency has determined that registrants may distribute and sell DEET products bearing old labels for 26 months from the date of issuance of the RED, and stores may continue to sell these products for 50 months from the date of issuance.

How to use DEET products safely: Consumers can reduce their own risks when using DEET by reading and following products labels. Statements on all DEET product labels will be revised to include the following directions:

  • Read and follow all directions and precautions on this product label.
  • Do not apply over cuts, wounds, or irritated skin.
  • Do not apply to hands or near eyes and mouth of young children.
  • Do not allow young children to apply this product.
  • Use just enough repellent to cover exposed skin and/or clothing.
  • Do not use under clothing.
  • Avoid over-application of this product.
  • After returning indoors, wash treated skin with soap and water.
  • Wash treated clothing before wearing it again.
  • Use of this product may cause skin reactions in rare cases. The following additional statements will appear on the labels of all aerosol and pump spray formulation labels:
  • Do not spray in enclosed areas.
  • To apply to face, spray on hands first and then rub on face. Do not spray directly onto face.
