Yes, spraying against cockroaches.
I thought maybe just as it is forbidden to plaster and paint during the Nine Days, maybe you also can’t spray the house during the Nine Days.

There’s no connection.

If I understood correctly, the Rabbi is saying that it’s permitted?
And I simply made a substitution between two things that aren’t related?
Because spraying is not connected to something that improves the house, but rather it is like cleaning the house?

As the Rabbi’s experienced troll, this time it didn’t come from me, but I have to point out and let the Rabbi know that this looks like trolling proper, and that questioner was fortunate to remain without the thread being deleted. And here the son asks: by what merit did that questioner deserve that his trolling should be displayed for all to see?

Questioner, correct, but this is not a substitution.

I wanted to update that I’m not trolling.
This really was a question I had.
Maybe to you it sounds ridiculous, but I don’t have the halakhic knowledge to understand certain things.

Questioner, do you know the custom that at the end of an episode of Impostors with Haim Etgar, or of The Swindlers with Adva Dadon, there’s a closing notice read by Haim Etgar in wording something like this: “On behalf of the troll it was stated: I wanted to update that I’m not trolling, etc.”
