Can we track a wormhole?

Worms that create wormholes - can we find and track them underground?

In a future earth, it was discovered that earthworms can actually create wormholes.

There's a lot more, and I'll ask other questions, but for now I just want to know if there is any way worms can be found and tracked underground.

For example, they could have a miniature radio transmitter or radioactive material implanted.

question

My story requires volunteers around the world to search for and discover tagged worms that once released can reappear anywhere and then go through a wormhole.

I don't know if or how far a radio signal from a tiny, low-powered transmitter can travel through damp earth.

The scientific question is: could electronic means be used to find and track electronically tagged worms underground, and if so, how far below that Earth and from how far away (for example, from a helicopter searching over a wide area)?

Note

Some Lumbricus terrestris can do this. We mark people with a transmitter and release them in a known place in a worm-proof box. They disappear from the box (and we know when they disappear because their signal disappears), but we don't know where they will reappear - maybe hundreds of kilometers away. That is why we have to discover them underground at their destination. There will be volunteers everywhere looking for them with recipients. When you see the approximate landing point of a worm (it will be underground), send us an email with its radio signature. This way we can track their wormhole journeys.

To prevent people from cheating (and likely boasting on YouTube that they found a worm) thereby messing up our records, they are asked to return them to us at our expense.

Confusers

Unfortunately, without knowing how wormholes work and what types of emissions they cause, we can't really track them as they appear.

How can they have a transmitter when they jump out of a wormhole?

The answer is either a trivial "yes" or far too broad. How far should we pursue them? What precision? Do you want to track them in real time or just know where they are? Can you catch them beforehand or not ...?

@Bewilderer - We recognize the worm, not the wormhole. See edit to ask a question.

Typical VLF radio transmissions can travel between 300 and 500 feet through soil and rock. This isn't exactly far (walk in a straight line for about a minute) - soil and rock will absorb very good radio signals. A tiny, low powered transmitter designed to be injected into a snail has one far shorter range

To be detected, a worm would have to be either very close to your receiver or very close to the surface. So I doubt you would get much in the way of the valid results
