If you’ve spent any time in Rust, you know survival is brutal. Blood is a resource you don’t usually think about—until you need it. Whether you’re crafting medical syringes or stocking up for trades, getting blood in Rust isn’t exactly straightforward. Here’s how I do it.

Animals: The Primary Blood Source
The most reliable way I get blood in Rust is by hunting animals. Here’s what works best:
- Bears and wolves yield the most blood per kill
- Deer and boars are easier to take down but provide less blood
- Chickens and other small animals give minimal amounts
When hunting, I always make sure to use a bone knife for harvesting. It significantly increases the amount of blood collected compared to using other tools.
Human Sources of Blood
Yes, you can harvest blood from other players. When you kill another player in Rust, their body can be harvested for blood using the same tools you’d use on animals. However, I’ve found this method to be less reliable and obviously more dangerous.
Collection Tools
Your harvesting tool makes a huge difference in blood yield:
- Bone knife: My go-to tool, gives the most blood
- Metal hatchet: Decent option if you don’t have a bone knife
- Rock: Will work in a pinch but provides minimal blood
Blood Farming Tips
If you’re specifically looking to farm blood efficiently:
- Find an area with high animal spawns
- Set up a small base nearby
- Hunt in cycles, allowing animals to respawn
- Always use the best harvesting tool available

Common Mistakes to Avoid

You might be making these errors that reduce your blood collection:

- Not prioritizing larger animals
Is There Another Way to Get Blood?
Not really. You can’t just harvest blood from animals or players like some survival games. It’s all about looting, fighting, or raiding.
