    That's a particularly well-written piece in Snopes, Rain Man. Thank-you.

    To give a little love to HF poster cevans, though, he suggested vanillin, the artificial (and wretchedly one-dimensional) stuff, not vanilla. ) ; and he didn't claim long or wide effectiveness. Whether Mexican or Madacascar, I wouldn't think of wasting real vanilla on critter-repellency. Don't know why you'd hike up a 20 mile beach with no place to hang a hammock; but say you did, and flies and noseeums, but not 'skeeters were the hazards, and you had nothing else but vanillin in the cabinet of the off-season rental........well, what the hell. There's much tastier 70% ethyl alcohol stuff in the cabinet to drink.

    So vanilla, or vanillin, is good for repelling bugs.
    How good is it at attracting bears?

    Meh...it's vanillin. They'll just wind up tasting like chicken between two pieces of Nilla wafer.

    There're better-tasting hikers out there, I guarantee it...


    As far as cats go, all I have is personal anecdote, not hard figures. However, with about six months of using the stuff under my belt, I can say that my three cats are just as neurotic and healthy as they ever were (OCD, I think, is part of the feline brain make-up).

    I use the spray type and hang my stuff outside for at least twelve hours overnight before letting the cats out to play in the morning. I check it for dampness before doing so, and if anything is still damp, I run it through the dryer without heat until it isn't anymore. Then, and only then, do I let the cats outside.

    So far, no changes in cat behavior or health...

    Vanilla and cats are wonderful and all (especially when marinated together and stir fried ...see my sig below) but the original question is still of interrest. Any chemical wizards that can answer if Permethrin treated stuff repels (and especially kills) bugs in general? Any Insecta types that it does not work on? I treat my hammocks etc with spray on Sawyers Permethrin and just did my Traveler yesterday (while on the Vario stand). A pure subjective test showed the bugs were on me at a half a dozen feet but in the hammock they were not there at all.

    I was thinking of setting up the Vario and Traveler on a freshly cleaned patio spot (near the backyard light/bug magnet) and checking the carnage in the morning. Problem is our Toad and bird population has learned that the light is a great source for breakfast and they eat the bugs very early. Oh and no dead birds or Toads either.

    BTW our neighborhood cats seem entirely unaffected by Permethrin treatments in my yard...my garden areas are still a giant cat box and the front yard is still the UFC (Ultimate Fighting Cats) ring.
    Mark is the name and If there is more than one way to understand what I just said....I meant the good one.

    I don't take it lightly. I love my animals and have had cats for going on 42 years; safe to say I'm a cat guy. They are nowhere near my gear until it is dried, but after that they have crawled all over my stuff.
    ===> +1 Here! I used a spray bottle of Permethrin all this past summer, and I also have a coupla cats who like to curl-up in my stuff. They have been fine .... I think once it dries, it no longer bothers them, just bugs, thankfully, and does a bang-up job of that!

    From the EPA website on Permethrin...

    Uses
    Permethrin is registered for use on/in numerous food/feed crops, livestock and livestock housing, modes of transportation, structures, buildings (including food handling establishments), Public Health Mosquito abatement programs, and numerous residential use sites including use in outdoor and indoor spaces, pets, and clothing (impregnated and ready to use formulations).

    According to Agency data, approximately 2 million pounds of permethrin are applied annually to agricultural, residential and public health uses sites. The majority of permethrin, over 70%, is used in non-agricultural settings; 55% is applied by professionals, 41% is applied by homeowners on residential areas, and 4% is applied on mosquito abatement areas.

    Permethrin is a restricted use pesticide for crop and wide area applications (i.e., nurseries, sod farms) due to high toxicity to aquatic organisms, except for wide area mosquito adulticide use. It is a general use pesticide for residential and industrial applications.

    Permethrin also has non-FIFRA pharmaceutical uses as a pediculicide for the treatment of head lice and scabies. The Food and Drug Administration (FDA) approves use of the pesticide-containing pharmaceutical under FFDCA.


    Risks
    Dietary

    Acute, chronic non-cancer, and cancer dietary (food and drinking water) risks from permethrin were below the Agency’s level of concern (LOC).
    Residential

    All non-cancer (dermal and inhalation) risks for individuals handling permethrin products in a residential setting were below the Agency’s LOC. All cancer risk estimates were also below the Agency’s LOC, except for the following scenario: mixing/loading/applying the EC formulation via sponge to horses.

    The non-cancer post-application risk estimates for adults and youth aged children exposed to an environment treated with permethrin were below the Agency’s LOC; however, the risk estimate for toddlers exposed to permethrin treated indoor surfaces (carpets) were above the Agency’s LOC. The cancer risk estimates for adults exposed to indoor surfaces treated with permethrin from directed surface sprays or total release foggers were also above the Agency’s LOC.

    The Agency considered post-application exposure to both outdoor residential misting systems and permethrin treated clothing. All scenarios were below the Agency’s non-cancer and cancer LOCs.
    Aggregate Risks

    The acute aggregate risk non-cancer and cancer estimate from food and drinking water does not exceed the Agency’s LOC.

    Aggregate short-term (1-30 days) non-cancer risk estimates, which include the contribution of risk from chronic dietary sources (food + drinking water) and short-term residential sources, exceeded the Agency’s LOC for toddlers exposed to permethrin through food and drinking water, and through post-application exposure during high contact activities on lawns and indoor surfaces. The risk
    driver for the aggregate non-cancer risk estimate was post-application exposure to permethrin on treated indoor surfaces (carpets).

    The aggregate cancer risk estimate exceeded the Agency’s LOC for adults exposed to permethrin through food and drinking water, and through postapplication exposure during high contact activity on lawns and indoor surfaces. Similar to the non-cancer aggregate risk assessment, post-application exposure to treated indoor carpets was the risk driver.

    All residential/recreational exposures are expected to be short-term in duration. Therefore, no intermediate-term (1-6 months) or long-term (>6 months) aggregate risk was assessed.

    EPA believes that the appropriate way to consider the pharmaceutical use of permethrin in its risk assessment is to examine the impact that the additional nonoccupational pesticide exposures would have to a pharmaceutical patient exposed to a related (or, in some cases, the same) compound. Based on a worse case scenario assessment, EPA estimates that the permethrin exposure a patient is expected to receive from a typical single application of a 1% and 5% permethrin pharmaceutical cream, respectively, is 450 to 2300 times greater than the combined exposure from the dietary and other non-occupational sources of permethrin. FDA has reviewed these estimates and determined that pesticide exposure in patients receiving treatment with a pharmaceutical permethrin drug product would fall within the expected range of exposure following treatment with permethrin drug product alone, and would not present an increased safety risk.
    Occupational

    The majority of occupational handler risk estimates were below the Agency’s non-cancer LOC at baseline personal protective equipment (PPE) (long-sleeve shirt, long pants, no gloves, and no respirator). For all other scenarios where the LOC was exceeded considering just baseline PPE, all occupational risk estimates were below the Agency’s non-cancer LOC with additional PPE or engineering controls.

    The estimated cancer risks for the majority of grower scenarios were also within the negligible risk range (≤3 x 10-6) or less with baseline PPE and gloves. However, a number of scenarios result in risk in the 10-5 to 10-6 range at this level of PPE, and either require additional PPE before the cancer risk estimates were below the negligible risk range, have no data available to estimate risk, or further mitigation measures were not feasible.

    For all agricultural post-application scenarios assessed, the non-cancer risks do not exceed the LOC (MOEs > 100) on the day of application, approximately 12 hours following application. Most of the post-application cancer risk estimated for both hired hands and commercial/migratory farm workers were in the 10-5 to 10-7 range. The highest risk estimates, in the 10-4 range, were for conifer seed cone harvesting and thinning of certain fruit trees.

    All non-cancer post-application exposure scenarios for military personnel and garment workers exposed to permethrin-impregnated battle dress or fabric, respectively, do not exceed the Agency’s LOC. Further, all of the postapplication cancer risk estimates for both populations were in the 10-6 range.
    My experience is that Permethrin, though sold as a pesticide/insecticide, has some noticeable repellent effects especially after a recent treatment of clothing. I have done the same day hikes in heavy mosquito-prone areas with and without permethrin treated clothing. BIG difference, enough so that the insects (when I wore treated clothing) were not especially bothersome.
