Gotta do some work in crawlspace. Lotsa critters naturally live there
- some creepy, some dirty nasty, some poisonous (Recluses & Widows
popular here).

It would be nice if I could bomb the crawlspace like with those ones
they have for inside the house where you set and vacate for a few
hours. Trouble with those is they spray high and I believe must be
vertical to empty.

Of course I would not do anything Darwin like go under house and try
and set and back out the 25-30 ft over pipes and ductwork. My thought
is fortunately at the far end is a dryer vent hole in the floor. I
could reach down from in the house and set a couple off. At the near
end (near to crawlspace entrance) I could discharge a couple there.

OK, beat me up here on this not thought through very much scenario.


Thanks for all the replies and input.

Followup:

The dasterdly deed was done today. First sprayed all room/closet
perimeters, outlets, vents, etc. Raid does make some short fogger cans
putting 4 in a box. Crawled to my waist through the crawlspace door.
Directed a couple by hand away and deep. Can tilt can pretty far when it
first starts to empty. Gradually tilt more vertical as it empties. Got a
whif and a couple of coughs just as I was backing (quickly!) out the half
body length. Boy I tell ya if anybody tried that going fully in just a
few feet they'd be a gonner.

Went inside and stuck my arm in the dryer vent hole at the far end of the
crawlspace with one and unloaded that on an angle in a circle. Pulled arm
out and covered hole.

Fortunately there was no invasion inside from those trying to escape.
Found a few later on in the day that made it up and croaked. While
working just outside after, I did see one actually severely limping away
next to the foundation.

So, no coroner or ambulance had to be called and no explosion.
