Dennis M; Hazelhurst, GA asks: I live in an old house with a two foot high crawl space under it. The crawl space is infested with spiders. I tried those bug bombs, but they didn't help. What else can I do?
Dear Dennis: If the insect foggers didn't work it means the aerosol pesticide didn't touch the spider. An insect fogger will kill the spider if it the insecticides reach where the spider is hiding. You need to carefully read the label of the aerosol bomb. Make sure it lists spiders as one of the insects it is meant to control. If spiders are not on the label, you're using the wrong product. Most home and garden stores like Home Depot or Lowes carry the products. You can find them at grocery stores like Kroger's, too.
Second, read the label to see the cubic footage the "bomb" is meant to cover. If you're trying to treat 4,000 cubic feet, but the label says it's meant to cover 3,000 cubic feet, you're going to be 1,000 cubic feet short of your goal.
Remember, when figuring cubic feet you need to multiply the width times the length times the height of the area to be treated.
Foggers do best when set standing straight up or propped up at an angle not to exceed 45 degrees. With only two feet of height in the crawl space the aerosol spray won't be able to float all the way to the back of the crawl space. The spiders are running from the pesticides and are hiding in the back corners.
A pest control professional would use a fogger machine that would properly fill the space with aerosol or with a pesticide dust or both. You may want to consider calling for help.

I have a problem with spiders inside my car. Could I use a bomb in my
little scion?
Thanks for your help.

Hell yeah! Bomb the scion with two bombs, one on the center console, one
under the car. However, i would cover all vinyl and leather surfaces with
cloths, and i would leave the car on the acc. position so you can set the
fan to recirculate low. Also doing it inside your garage would be good
because it will hopefully chase buggies out of there too.

My husband is going to set off a Hot Shot No-Mess Fogger (all that Home
Depot had) in our spider-filled garage before he starts rearranging
everything. The garage is reached from the house through a door in the rec
room. The rec room is where my aquariums are. We are locking and taping
the door. Is there any chance of that stuff being tracked in from the
garage or seeping through the wall (the wall between the two is
waterproofed) or chimney?

Foggers work best on flying insects. The spiders will simply move to more
secure hiding places as soon as they get a whiff of the pesticide.
Elimination of clutter is your best spider defense.

Can you use a fogger in just a bathroom? There are so many gnats in my
bathroom and I don't know where they are coming from. They seem to die
pretty fast. They're all over my tub, shower and floor. Only the bathroom
seems to be a problem.

The pesticide fogger will knock down the adult flies, but it won't solve
the problem. Please read the article at this link:

I have bird mites and need to fog the entire house. I wanted to us Hot shot
bedgub and flea fogger in my garage. Will it hurt my paint on my car. The
car does not run so it must stay in garage.

Cover the car with a tarp before using the fogger.

I killed two mice inside my house and have had something biting me for 3
months. Think it is the mites from the mice but no exterminator in my area
deals with this type of thing and treat me as if I am delusional. Have
used Ortho Home defense but not getting rid of them. What else can I do.
I am willing to get rid of stuff as they were in a chest of drawers what do
they like to hide in, have lots of books. I boil my clothes to get rid of
them, haveen cased mattress, need some direction. Also have them in my car
really bad, what do I fog with and hnow.

If you cannot produce an insect specimen you will have no luck trying to
work with a pest control company.

Hey, I was considering bombing my crawlspace to rid it of spiders (they're
everywhere!). I rent, and the house is small, but I hate fighting them off
every time I head under there for some wiring changes (cable, etc.). I
also think it will help keep them out of the house itself. My main concern
though is will the fogger leak into the house and potentially hurt my dogs?
I have two large size dogs and don't want the fogger to poison them. They
like to lick things and it wouldn't be beneath them to lick the floor every
once in a while, in true dog-like fashion. Will the fogger harm my pups?
I bought it from Kroger and it's rated for spiders.

Jordan - That is exactly my question. Did you figure out what to do?
Thanks. K

There are these really tiny bugs on my window sill and sometimes in my
bathroom sink. They are really tiny. About the size of a tip of a needle.
What are they and is there a way to get rid of them? My bed is right next
to my window. Should I move my bed?

We have a modular home with no basement. My husband said their are tons of
spider eggs under the house and we do see spiders in the house more than I
would like. Could we use a fogger or a bomb? I was thinking of setting one
off under the house and one in the house at the same time as I am worried
if we just do one under the house, they will all come inside. Is that a
good plan? Also, will the fogger or bomb even harm spider eggs?
Thank you.
