A few weeks ago, I had a surprise one morning when I opened my mailbox to put in a letter. Inside were dozens of medium-sized black ants busily tending a nursery of a hundred or so cream-colored eggs.

Well, thank goodness for the Internet! I quickly scanned the Web to see if anyone else had this trouble, and sure enough, quite a few people did. They had recommended some courses of action and I tried several, just in case. Whether it was one method in particular or the combination of all that did the trick, the ants have not returned.

In case you ever have this happen to you, here is what worked for me:

  1. Clear out the ant nursery (Not a pleasant task. I felt sorry for the ants, but it had to be done).
  2. Wash the interior and outside of the mailbox, and upper part of post, with a liquid disinfectant.
  3. Wash with vinegar.
  4. Wash with soap and water (I used liquid hand soap).
  5. Place a fabric softener sheet inside the box, over any entrance holes (The mail certainly smelled fragrant the first day, but the scent faded after that).

Ants in the mail

I had the same problem. My reaction was to put one of those small plastic ant products that you can place around your house to attract the ants. They take it back to the colony and it sends them to their final farewell. I've had the same one in there for over a year and they have not returned. Just place it in the back of the box. Problem solved!

ANTS IN THE MAILBOX

You may want to notice if they appear during a heavy rain. It rained hard last evening. Thousands ants were in the mail box 2 hours ago when I checked the mail. I went back a few minutes ago to clean up after reading about it. They are gone, just a few were left. They left on their own after the rain. It may take a few hours including overnight. I am glad no killing was involved.

Let the Ants do the Work

No need for you to clean out the nursery. Simply leave the mailbox open for an hour and the ants will relocate it themselves. (But they will try to move in again and again if other measures aren't taken to prevent them from doing so.)

my neighbor lady saw me

my neighbor lady saw me spraying poison in my mailbox and came over with a medicine cup with two mothballs in it, she said she had the same trouble with ants but just put the cup w/mothballs in the back of the mailbox, the ants won't colonize there. it worked!! they haven't come back, but the mail will be stinky. haven't tried a dryer sheet, good idea & less stinky! :)

So I've retrieved my mail,

So I've retrieved my mail, cleared out the ants, washed the mailbox with a disinfectant and now have left the mailbox open. Tomorrow, when George delivers my mail, will he then close my mailbox? Or, will my mail be visible to all passers by?
