Ant control collars

This started off as bionic legs for ants, but here's a simpler option:

Ants, if I remember correctly, establish trails with smell. For every ant that finds a good source of food, a trail gets established, and then reinforced as all the other ants follow it - until eventually they're all marching merrily along to your larder, eating the popcorn and leaving footprints in the butter. (Or is that elephants?)

Anyway. The solution is simple - establish an alternative route which avoids your larder and sends the ants out to more healthy, outdoor-type foraging grounds. But since you don't smell like an ant (apologies to any literate giant ants reading this), how do you do it?

With the power of magnetism! The AntCollar(TM) is a little magnetic ring which fits around a worker ant's midriff. Simply catch a few of these little chaps, attach the AntCollar, and then place a few of the carefully calibrated AntWalk(TM) MagnetPads on top of the existing trail. These U-shaped channels have repelling magnets on either side, so once the ant is on it, he can't simply climb over the edge. Instead, by using a few non-magnetic offramps, you get to choose where he gets off (interestingly, if the cheeky fella decides to try and go round the back, he'll get stuck to the back of the magnets. Flick him off - he'll learn.). The more times your collared ants use the track, the more established it will become and eventually they'll all be trekking off into the garden! Yay! Pour encourager les autres, we suggest that you put a bit of sugar out at one of your chosen offramps to start with, just to give him something to take back.

Now, all we have to do is wait for someone to invent the AntCollar applicator. And find some ants. Here, little ant...
