Hi Mary & All,                                May 6, 2014
    With regard to the effects on Arthropods of wearing Permethrin =
treating clothing when in the woods it seems clear to me that, even if =
widely used, the effect would be vanishingly small because (if I =
understand this correctly) exposure must be by direct contact with the =
clothing, exposure will be transient and the area of exposure will be =
limited (a huge area of cloth is not left hanging in one place).=20
    The direct effect of motor vehicle traffic on flying insects would =
probably be at least one million times as great.=20
    A few years ago it typically took 2 decades for someone to get a =
clear grasp of even a narrow field of study so there was time for =
reflection. The internet now furnishes rapid access to vast amounts of =
information and exposure to countless instant experts. So one should =
welcome verifiable raw information and be wary of perhaps faulty ideas.=20
    Gulliver's travels in Laputa is a good place to start. Whatever =
happened to that project to breed hairless sheep ?

  I hope people will consider very carefully before applying such =
pesticides as bug b gon and others to their lawns and gardens. Google =
them and check their toxicity to pollinators and other beneficial =
insects. Surely at least those on this nature living list can be =
leaders, communicators and advocates for dealing with the less than 2% =
of insects considered pests in other ways rather than these incredibly =
poisonous treatments.=20
  As for ticks. Tuck your pant legs in your socks, wear bug jackets and =
gloves etc. Washing pesticide soaked clothing introduces these chemicals =
into our water.=20
  Pyrethroids have been found to be unaffected by secondary treatment =
systems at municipal wastewater treatment facilities. They appear in the =
effluent, usually at levels lethal to invertebrates.

  With kindest regards

    A minor correction, Jane, permethrin is the
    man-made analog of pyrethrin and permethrin is
    available in far more insecticides than pyrethrin
    (because permethrin has a longer shelf-life, a
    longer active period and is cheaper to include in
    insecticide formulation).
