Ok so here goes: A splash of coffee fell out of my mug and may have touched the feeder insects I intend to give to my beardie. I looked over the container, it doesn't look like any coffee actually got in (just splashed the ground near it). Would the crickets die first or would feeding them (if they potentially got some coffee in them) harm my beardie?
My unprofessional opinion would lean towards they should be fine. If you're really concerned, feed the crickets their regular gut load diet for a day or two and you'll be safer than sorry.
Your beardie will suddenly become very productive and be able to whip out those reports left and right before finally crashing on their basking rock for a nap.
No I’m kidding, a secondhand splash of coffee won’t do anything. The cricket might start feeling super motivated, but your coffee connoisseur lizard is fine.
