First, you start inadvertently leaving bowls of tic tacs candy laying around the house. You know, like in a cubard, or under a sink. Make sure to use all the tic tac colors at first; then eventually whittle down to just the white ones. Span this out over a few weeks so no one thinks twice when they see a container of white tic tacs.
And then next thing you know, there's a tub of larvae under the bed, and no one thinks twice about it.
Excerpt from Robert Crais' "The Monkey's Raincoat:" "She took another microscopic bite of her sandwich, then pushed it away. Maybe she absorbed nutrients from her surroundings."
