I don't remember the episode, but its about writing checks and one of them is to the bug man.

What type of bug killer would they have sprayed at the Cleaver home?

There is an episode where Beaver comes out the front door, and Gilbert says, Beaver, you have bugs. Beaver says he just took a bath, or close to that. And Gilbert says no, he meant on the bush. And there's another episode where Beaver asks Eddie to help him pick the bugs off--Eddie relents and helps because he wants Beaver's help to make up with Wally, probably when he accused Wally of stealing his girl in a season 4 episode.

But those aren't the episode. There's another one W&J are talking about a guy coming over to spray for the bugs on the plants. Maybe later Ward was writing a check. It's probably a season 3 or 4 episode.

They sure had a lot of problems with bugs on the shrubs and plants. Maybe the guy used DDT--it wasn't banned back then.

I think it’s the one when Beaver walks in and hears them talking about winding up in the poor house with all the bills. Ward is writing a check to a guy named Hogan who kills bugs.

There’s another episode when Ward asks June to describe the bugs because he has the exterminator on the phone and she goes into detail about having small wiggly things coming from their head. Don’t know the episode but it’s the new house.

In that second episode I think they decide to spray the bugs themselves because the guy wants to charge too much.

Instead of painting they should have had Andy spray bugs.
