They're in my pants

Whilst making a bottle for His Highness the Baby I noticed a few mini-ants running around the surface. It was 3 am so I didn't want to pay much attention to them.

At 8 am when I made Her Holiness's coffee I noticed them again, this time around the sugar bowl.

Normally I'd just call the exterminator and have them chemically removed but we're moving house in less than a month and I don't want to spend the money.

So my question to you, dear reader, is;

Short of hiring an anteater from the local menagerie, do you have any cheap and easy ways to abate the flow of ants into an apartment?

Answers in the Comments please.
