DE and Ants

This might just be a coincidence but it has already happened twice. I have a pretty bad flare up on my hands at the moment and the dried up fluids coming from my flare ups is annoying to clean up so I put on a piece of tissue on my mouse when I'm using it. There has been an ant infestation near my desk that I have yet to resolve. It has now happened TWICE that ants gather on the tissue (with the fluid). Is it a sign of something like maybe too much sweets may be a trigger or is it all just a coincidence?
