Is it a weevil? Those come from hay.

Have you seen any of those bugs in his pellet bag/container? Do you have a lint roller? That would be a lot wider than a piece of tape, and you could roll it really quickly (but carefully) across Breintje’s fur next time you see it.

Hmmmm, does have a hard carapace that covers the whole abdomen, with a split down the middle? That would mean some sort of beetle. If it is a beetle then it prob is coming from the hay or pellets, even if it’s not a weevil specifically.

It sounded like a tiny beetle to me, too.

Some sort of grain beetle maybe? They can be attracted to hay.

It does sound like it could be a grain beetle, I looked up the types that are common here, their latin names are Tribolium or Tenebrio. But they’d have no business in Breintje’s fur.

Yes, but they could get “lost” on him if he dives into the hay.

I agree. I have found tiny oval black beetle like bugs in their food when I get their cubes from the outdoor farm store.

It must be a common pest for sweet grasses.

I’ll try to post a photo sometime.

I am comfortable using  a little diatomaceous earth when I vacuum or in their box/ fur if I see a health issue.

Many owners worry about aspiration and intestinal safety.

Diatomaceous earth is safer than powdery dirt in the yard; sand in the dig box  and ‘bedding’ sold at pet stores which has been proven to cause lung cancer, asthma and more respiratory issues.
