I can't imagine spraying Drano around on my walls, ceilings, or floors. It might kill lots of things. What if it dried on the ceiling, flaked off, and fell into my coffee?

It would be a little safer to use a commercial insecticide, but you, your family members, and you pets might absorb the neurotoxins that are used in these insecticides. There are some organic insecticides that would not endanger people so much.

If you kill all of the Spiders in a house then there is a chance that some species of spider that is actually a problem biter will be in the first wave to recolonize your house, and then you will have an unchecked population of something you don't want. Previously, the many other kinds of spiders (most all of which will eat other spiders) would have kept the numbers of the problem species down.

If you find some spider that you do not want where it is, perhaps because it likes to make a web right in front of your security camera, the best thing is to put a drinking glass down over it, slide a 4 x 6 card under the glass, tip the whole thing right-side up, take the spider outside, and let it go far enough from the house that it will be unlikely to wander back in. Drano is a cruel way to kill anything.
