Not yet had to deal with silverfish......ants from time to time including this week.....just suck them up with the little hand vac and relocate them outside......two mice which I caught and released although one did perish in a neighbours lavender bush when it caught fire.....
Not in my nature to squish and squash......but I can see why some would do that....x
We used have alcoholic neighbours, they were hilarious, really nice but drunk, and we have adjoining leans twos, but they rarely took their bin bags out so we had rats coming into our house. We had no option but to deal with them.
Silverfish are harmless but they will eat through carpet and wallpaper. They can be dealt with with ant powder.
I find ants quite fascinating though so I really don't like killing them. They just can't live in my house.
I used to obliterate them into many thousand pieces. Now I put a glass over them and slide paper underneath and put them outside. I'm quite proud of my progress.
