What home improvement finally helped with your cockroach problem?

Cockroaches are honestly one of the most frustrating things to deal with at home. You can keep the kitchen clean put food away take the trash out and still end up seeing one crawling around when you least expect it.

The frustrating part is that getting rid of the ones you see does not always seem to solve the problem. Sometimes there is something else going on like moisture under a sink a small leak food getting into a hard-to-reach spot or a tiny gap they are using to get inside.

It seems like finding out why they are there in the first place can sometimes make a bigger difference than just dealing with the ones you happen to see.

For anyone who is dealt with recurring cockroaches at home what ended up being the thing that finally made a difference?

Was it something you found around the house a repair you made or just a small change in your routine?
