Spider eating mulch

[PinkMetal]

My avicularia metallica is eating a cricket with substrate stuck to eat. He is ingesting the mulch as well. What should I do?

He won't be able to ingest the mulch. The mulch provides no "liquid" to the tarantula. When a tarantula bites a cricket, the inside of the cricket turns to liquid from the venom. When a tarantula bites mulch, it does nothing because mulch isn't an insect. Your tarantula will consume the liquid from the cricket and leave a bolus behind. This is what's left once the cricket is drained dry. The mulch will be with it or dropped along the way.

Actually tarantulas will suck the moisture out of the substrate in the wild and in a enclosure if thirsty.

tarantulas have been eating dirty bugs for millions of years. I suspect your's will be fine doing so, too.
