[quote=spdrun]You’ve got to be kidding — when they started the construction on the riverfront near me (replacing the foot-overpass over the highway), my building’s back alley was suddenly infested with prime examples of R. Norvegicus. Thankfully ended once construction was done — hearing squeeeek, squeek, squ outside my bedroom window at 3 am got old.[/quote]
You can buy some pretty good rat poison. Just drop enough out the window that it will be gone by morning. Scatter it well so domesticated animals won’t by chance get a dangerous dose. Rats would be wiped out pretty quickly.
