All That For???

So FINALLY our landlord paid for an exterminator to come and set some traps for our little mouse friends. This is the funniest part ... he had those tiny tin plates (like muffin cup sized) that he filled with peanut butter and poison (set behind objects where the kids can't reach them of course). They're supposed to kill and dry up the mice from the inside. It seems way too simple but I keep thinking that sometimes the most simple things are the most effective! Should have I told the landlord that I think that maybe when Hubby chased Speedy into the bathroom and down the pipes into our heaters, that he finally trapped him and I don't think he's been back! Nah...
