[sci.bio] Brown Recluse Spiders

Mary.Lane@ofa123.fidonet.org (Mary Lane) (09/08/90)

Does anyone know something that would kill the Brown Recluse?  I don't have 
roaches; I have those mean, fast, big spiders, and I don't know where they're 
coming from.

     Are you sure (no flame intended) that what you have are Brown
Recluse spiders?  In my experience (7 years living outside of
Columbia, Missouri, AKA Brown Recluse Nirvana) none of the underscored
descriptors really fits the Brown Recluse well.  1)The consequences of
a bite are pretty mean, however, the spiders themselves are fairly ...
well reclusive.  They often have to be stepped on or otherwise
pressured into biting.  Most people get bitten by not shaking out
stored clothing or shoes.  You put them on, squish the spider and it
bites.  2) Most spiders can really move if disturbed, however the
Brown Recluse spends much more time sitting than running. 3)As spiders
go the BR is pretty normal size, rarely larger around than a quarter
(diameter, including legs).

     The best diagnosis of BRs is the body markings, which are rather
violin like in shape.  It sounds like what you have are some sort of
wolf spiders.  They are a bit larger than BRs, VERY fast (they are
"hunting" spiders which don't spin webs), and are aggressive in their
movements.  They are brown/grey in color as a rule.  They often eat
roaches, ants, and other household pests.  If you can catch one (dead
or alive) your county agricultural agent can get it identified so that
you know what you are dealing with.  Even urban counties have a county
agent.  We pay for them with our taxes, however few of us know that
they exist never mind use their services.

     If you have wolf spiders, I'd just leave them be (integrated pest
management, and all that).  If you want to be rid of them, good strong
bug spray around the baseboards should do it.  If they really are BRs,
you need to concentrate on spraying the closets, garage, basement and
other dark, usually undisturbed places.  Good luck!

       I think I know the ones you talking about.  I don't think
they're mean though.  They're certainly mean-looking.  We call
them (here in Florida) the brown mosquito spider.  They are
HUGE, they're a good 6" to 7" across (toe to toe, so to speak),
and when they run across your wall you can here the pitter-patter of
those toes.  I was told that they are harmless, however, I had one
run up my arm and I almost broke my leg when I knocked over the
coffee table trying to get my shirt off (not to mention the heart
attack I had).

       I sprayed 1/2 can of Raid on one of them, he passed out and
about 5 mins. later he got up and walked away.

As someone else posted, what you have are probably not Brown Recluse,
and non-venomous spiders can be real handy to have around to help out
with cockroach control and such.  I actually used to keep a couple of
tarantulas around for that job.  They worked great and I was never
bitten.

But if you really want to get rid of them, spiders are sensitive to
many of the same things that kill insects: bug bombs, massive over-
doses of Raid, combat boots, ball peen hammers, etc.

Raid, yes, but many other insecticides are not effective against spiders
because of their book lungs.  I can't tell you, off the top of
my head, which compounds are effective against which groups
and why, but Larry Lippman's cat could, I'm sure.

	My cats can most assuredly tell you three things about spiders:
(1) spiders are fun to watch; (2) spiders are fun to catch; and (3) spiders
are just *yummy* to eat.

	:-)

	I personally can't tell you much about spiders.  I can tell
you about the effects of various insecticides on *people*, but, alas,
not on spiders.  This obviously won't answer your questions.

	I can, however, tell you that in an indoor environment cats
are a good "natural" insecticide effective against spiders.  :-)

	Hmm, sure does sound like wolf spiders to me (or else thier close
relatives - the tarantulas).

	And the original poster is not the only one who has gotten wolf
spiders and brown recluses miced up.  When I was much younger I used to
think the enormously common, somewhat smaller, wolf spider of eastern
Kansas was the brown recluse.  After all, I had been told how nasty the
brown recluse was, and these were the *only* brown spiders I had ever seen.
I may not have been fully corrected on this until I took a field natural
history class at university.  There I got to know spiders quite well.

	I have also, since then, seen brown recluses.  They were rather
smallish, non-descript brown spiders huddling under some old boards.
(I didn't bother trying to get a closer look the see the 'violin', I
didn't relish the idea of getting bitten.)  As near as I can tell they
are rather similar to black widows in body shape and markings - except
for being a very dull color, and *much* smaller.  [A black widow is a very
stunning black with a distinct red marking]

 I spray Dursban (1oz/gal) (active ingrediant in the Rid-A-Bug spray but
I mix it from the brown bottle) inside every couple of months. Dead
spiders, millipedes, palmetto bugs, scorpions and earwigs appear along
the baseboards. So if you want to kill bug daid, try that.
