I am getting large spiders in my shop . I mean huge hairy ones. What kind of
spray works the best that I can mix up an put in my spayer to kill these
Just wondering what you guys have used with succes ?
What would like a professional use , say like Orkin or other contractors ?
You might try Talstar or Bifen but spiders are a different breed, not sure
it will kill them it might just make them stay away. Do a search on Ebay for
Talstar so you will know what to expect for a price.
I would imagine using an aerosol bomb or fogger:
You may want to cover plastic seats on atv's before setting off bombs or
doing extensive spraying as finish may be affected.
I'm not fond of the large spiders that pop up in my family room and lay
down some of the sticky mouse traps that will also catch bugs.
Remember that spiders are not insects, so the common insecticides made
to control roaches, ants, etc will kill spiders on contact, but not so
effective as a residual control. Foggers will only kill what spiders the
fog contacts, there is no residual left behind. Micro encapsulated forms
of insecticides will have the longer residual for them, but with the
larger spiders even though they have enough insecticide on them to kill
them it can be hours if not days before they may die. Also treat a band
around the perimeter of the structure to help reduce some of the population.
Generally, I leave spiders alone. In my house, in my shop, in my garage, in
my garden. They don't generally setup housekeeping unless there's adequate
food supply. Otherwise, they move on. They are nature's version of insect
"roundup". Generally, you leave them alone, they pay the same favor. You
probably need something more than to kill the spiders if they've been there
for a couple of weeks. Hopefully, you'll figure it out without chemical
I haven't seen Garden spiders in a few years, but this year they seem to
have had a resurgence.
I had this big beautiful intricate web strung between a Japanese Maple
and a Rhododendron. It was about 2' across. My wife accidentally walked
through it and destroyed it.
The next day, there was another great web between the rear view mirror
and the door latch end on my truck with an anchor going down to the
driveway. I felt bad destroying it so I could move my truck. I'm
looking around for another that I can photograph.
Got a spider that had a 6 foot web between the top rail and ceiling on front
porch. He was there for about a month. He moved to the fence. Made web
between the fence top and the fence post that extends up 8' at the gate
entry. He's about 3" across at the legs, black and yellow in color. Same
species spider made web between the ground and the top of the front tire on
my parked pickup. Both have been out those locations for about a month. I
will have to drive my pickup soon, hope he moves okay.

This time of the year is spider breeding season, so the males are
wandering around looking for a mate. These spiders most likely have been
in the shop the whole time and now your seeing them out in the open.
Before you bomb the place or lay down a bunch of chemicals that will kill
the spiders and otherwise harm you, I would highly suggest that you look
at spider traps. These have worked very well for me and this is a great
time of the year to use them. They have a pheromone that attracts them to
their sticky demise!
The garden article database.
I did forget to mention that I had a lot of crickets in the early summer so
I sprayed for them. I have swept the ones up in the middle of the florr but
I haven't moved things around from the walls to sweep all the dead ones.
Could this be attracting the spiders ? and keeping them alive ?
Spiders catch live prey. An urban acre is supposed to have a population
of over a million spiders...an acre of meadow land can be between 2-5
million spiders. Along with if you are in a part of the country that has
been extra wet this year there will be extra foods for spiders thus
allowing even higher spider numbers in a given area.
HHHHMMM lets see , we got record rainfall this year and I live on an acreage
. I guess this might be my problem . But I have lived in tow many years and
won't ever go back. So, I guess I can live with the spiders but I would
still rather not.
I use the hedgeapples every year. I place them on Aluminum foil in corners
and under the open countertop sections of my workbench. I can't say that
they work but I don't see very many spiders...of course I don't see any
elephants at all so they must work for them also...:>)
Big question is, what kind of spiders are they. Mostly all spiders if
left alone will not be a problem. Some of which can easily be handled
Have you looked into what type of spiders they are?
If they're BIG, they could be wolf spiders;
Rather harmless and will avoid you.
Or are they this one;
Which gives good reason to destroy them since they will bite on contact
and cause medical issues in 25% of their bites or so.
I've got the latter in my house actually. Just moved in a month ago and
the place was infested. Haven't done much to kill them however. In fact,
just general cleaning and living in the house keeps them away since they
are indeed recluse.
At any rate, see if you can ID the type of spiders they are before
stomping on them. They may be providing a nice service to you by keeping
the insect population in your shed in check.
Oh, if you DO seek a pro, they will do a 2 or 3 step process. First will
be a toxic bomb that will kill anything living on contact. The second
will be a powder based product.
Problem is, spiders breath through their abdomen, which alot of spiders
keep off the ground. Without that contact the common sprays do not work.
Have crawl space access under the shed? Try sevin dust at the edge of
the crawl space or just under it. Just make sure kids and pets can not
get to it.
