Feed A Mosquito: How to Get Blood (Source & Steps)

If you're trying to work out how to get blood in Feed A Mosquito, the answer is simpler than it looks: blood isn't an item you find, buy or extract — it's your own health pool. Two things fill it: the life-gain seat in your base, and automatic regeneration. You confirm you have some by reading the on-screen health number, and you spend it by letting your placed mosquitoes drain you until their feed percentage hits 100%. That's the whole loop, and it works from the first minute of a fresh base.

What blood actually is

The game's resource called blood lives in your health meter. In a full playthrough, the narrator stands at his starting base's sit spot and concludes: "it seems like this health here will be my blood, in this case." Every mosquito you place then draws on that same personal pool: "every mosquito I put in my base, I'll need to be feeding it with my own blood."

One pool, two jobs — as the same player puts it, the health you gain "serves both for us to feed the mosquitoes at our base, but also as resistance every time we go to defeat the mosquitoes in the field. So, it serves two purposes." Building up blood before a boss fight isn't wasted prep; it's the same number you'll spend on feeding afterwards.

Where blood comes from

Sit on the life seat in your base

Every base starts with a sit spot that grants life — it's there in the first minute of a new save, already shown at level 1 and upgradeable ("we can already see that we can upgrade it because it's at level one"). Walk to it, sit, and stay: "we'll need to stay here for a while gaining health." The number climbs while you sit. Returning to the seat between activities is the game's standard rhythm, including sitting "a little longer" to gain life before a field fight you'd otherwise lose — "And every time we gain health, we get stronger."

Let it regenerate

The pool also refills on its own, even while a mosquito is actively draining it: "It sucks my health, but I recover it on my own. See that over there? It's automatic." During another feed: "our health fills up automatically." Regeneration is slower than a good seat, but it means a drained pool is never permanent — walk away, wait, come back.

Upgrade the seat to raise the refill rate

Upgrades are bought with the cash your mosquitoes earn ("we got more money, enough to make another upgrade to our life chair"), and the furniture gets progressively sillier. Across two playthroughs, the seat line includes a toilet ("We are literally gaining life sitting on a toilet" — the player calls it his IV after a heavy feed), a bench quoted at 40 health per second, a hot tub, a couch at 80 per second, and a bed.

Treat that order as an example, not a fixed ladder: the two runs show different upgrade lines, and only those two rates — the 40/s bench and the 80/s couch — are stated anywhere. Most tier prices never appear on screen; one run mentions needing 15k for a much bigger health pool without tying the figure to a named tier. One video also mentions paid 5x/8x multipliers without ever showing their effect on blood gain, so don't budget around them on this evidence.

How to collect blood, step by step

1. Return to your base. Feeding and field fights both drain the same pool ("every hit he lands on me, my health drains really fast"), so head home after either one.
2. Sit on the life seat and stay put. That's the entire action — the health ticks up while you sit.
3. Watch your health number rise. The total is readable on screen at all times; players quote exact mid-session values like "I ended up with 56 health," "I now have 600 health" and "We have 150k health."
4. Stop when the number covers your planned spend. Gate a big feed on the reading, the way one player does before hatching a large larva: "I'm just not sure if I have enough blood for it."
5. Repeat as needed. Between sits, automatic regeneration keeps topping the pool up, so a small shortfall can also just be waited out.

Those readings are session values from two recorded playthroughs, not universal targets — what matters is that your number visibly rises while you sit and that you can read it before spending.

Constraints worth knowing

• Blood behaves as a meter, not an item. You raise the number and spend it where you stand — nothing in the game's observed loop has you picking blood up, banking it or moving it around.
• One feed at a time. "Please tell me I can feed multiple mosquitoes at once. Why can't this game let me do that?" Expect to feed placed mosquitoes one by one.
• Drain scales with the mosquito. "The better the mosquito, the more life it will drain." A weak common barely pulls; a shock mosquito "literally instantly takes all my blood"; and even 1 million health wasn't enough to fully feed a Kraken-sized mosquito in one attempt. If a feed empties you, refill on the seat — or upgrade it — and retry.
• The same pool protects you in the field. Whatever you plan to spend on feeding, you'll also want in the tank for boss fights. Don't start one dry.

The basic route is free: the seat comes with your base, regeneration costs nothing, and you don't need to redeem any codes (our codes page tracks those) or spend Robux to refill.

From a full pool to feeding

Once the number looks big enough, walk over to a placed mosquito and start the feed at its spot — it latches on and drains you automatically while a percentage meter on the mosquito climbs, and 100% is the finished state ("fully fed up"), leaving it bigger and paying more cash per second than before. For the feeding side in detail — payouts, growth and what a fed mosquito is worth — see the feeding guide. And once your cash income supports it, the blood farming page takes over from there.
