I grab my Bug Net two ways, both of which are more efficient than searching blindly. Early on, I craft one at a Loom using 8 Wood plus 3 Silk (spun from 7 Cobwebs each at that same Loom, which itself needs 12 Wood at a Sawmill). No Sawmill yet. I’ll hunt underground cabins for a pre-placed Loom. Alternatively, once I’ve built a valid house with walls, light, and furniture, and stashed 50 silver, the Merchant moves in and sells the net during daytime hours (4:30 AM to 7:30 PM). Either path gets me catching fireflies for portable glow or butterflies for bait before my first blood moon hits, and using these critters effectively improves early game survival.
Where to Find the Bug Net in Terraria
Wondering where you’ll snag your first Bug Net. You can grab this essential tool a few ways, depending on your platform, as mobile and console players sometimes get lucky with starting gear. Otherwise, you’ll need to do some legwork. Smash a Grasshopper and you might score one. More reliably, though, you’ll want to focus on crafting. That means gathering 1 Wood (chop any tree) and 1 Silk (spun from 7 Cobwebs at a Loom, or found in chests).
Once you’ve got your Bug Net, head to forests and grassy biomes where butterflies, fireflies, and caterpillars flutter about. Corruption and Crimson zones work too, though critter variety gets weird there. Catch them, release them, or stash them for later quests.
How to Craft the Bug Net From Scratch
If you’d rather skip the hunt and build your own Bug Net from nothing, you can do so with relative ease. Assembling it yourself requires 8 Wood and 3 Silk, plus access to a Loom (which you can craft yourself with 12 Wood at a Sawmill, or find one in underground cabins). Gather Silk by hunting Spiders in caves; they drop it directly, no Cobweb processing required. Once you’ve got your materials, stand near that Loom and open your crafting menu. The Bug Net appears instantly. No Merchant needed, no gold spent, and you’ve completed the task through self-sufficient crafting.
| Material | Quantity |
|---|---|
| Wood | 8 |
| Silk | 3 |
| Loom | 1 (crafting station) |
| Spider hunting | Patience |
| Satisfaction | Unlimited |
When the Merchant Sells the Bug Net
I’ll walk you through exactly when you can grab that Bug Net from the Merchant, since timing’s everything here. First, you need at least one valid house (a room with walls, a door, a chair, a table, and a light source; basically 10 tiles wide and 4 tiles high, give or take) and 50 silver coins in your inventory to make him show up. Once he moves in, you can buy the net during daytime (roughly 4:30 AM to 7:30 PM in-game). Don’t waste your night waiting around.
Minimum Housing Needs
Where exactly does the Merchant set up shop, and what does your town need to look like before he’ll sell you that shiny Bug Net? Your housing needs to hit 8 valid units before he’ll stock it.
Here’s what you’re building toward:
- That cozy 60-tile space (10 wide, 6 tall minimum) with proper walls and light, so he feels welcome.
- A valid house with a table, chair, and light source—no shortcuts here.
- An empty inventory slot, because nothing stings like missing the purchase.
- 25 copper coins saved up, which is the baseline cost for belonging.
Once your merchant moves in and sees you’ve built a real community, he’ll hand over that Bug Net.
NPC Spawn Timing
Now that your town has those eight houses built and the Merchant has moved in, you’re probably wondering when you can actually buy that Bug Net. The merchant won’t stock it immediately. You need to wait two full in-game days (48 minutes of real time, give or take) before his inventory refreshes with the net. It feels long when you’re eager to catch fireflies. If you’ve rushed into Hardmode or shuffled your NPCs around, double-check that he’s actually present and not crowded out by events like goblin invasions. Sometimes you’ll need to let him respawn or visit fresh the next morning. The wait allows his inventory to refresh properly.
Daytime Purchase Window
When exactly can you snag that Bug Net once the Merchant finally has it in stock? Timing matters because missing the daytime window means waiting through another long night.
The Merchant only sells his wares during daylight hours, roughly 4:30 AM to 7:30 PM in-game time. Once dusk hits, he shuts down shop completely. I always rush to find him the moment morning breaks, coins in hand, because that Bug Net won’t wait for stragglers.
Here’s what I’ve felt during this chase:
- The panic when I realize it’s almost sunset and I’m three biomes away
- The relief spotting his hat bobbing over that hill at dawn
- The frustration of nighttime inventory checks with zero options
- The triumph finally clicking “buy” as birds start chirping
Get to him early in the day to secure your purchase.
How to Catch Critters With Your Bug Net
Why fumble around while butterflies dart past your nose. Grab your Bug Net and catch some critters. Equip it in your hotbar, walk right up to a fluttering target (fireflies at night in forests, butterflies during daylight in grasslands), and hold the action button to swing. Timing matters, especially with fast movers like moths that love the Hallow at night. You’ll miss less when you press against walls or corners, trapping them. Higher-tier nets, like the Golden or Lavaproof varieties, swing faster with bigger hitboxes and represent a worthwhile investment. Caught critters go straight into your inventory, ready for the compendium or release. No bait needed, no complicated setup. Just you, your net, and whatever skitters across your path.
Crafting Uses for Your Bug Net Critters
Once you’ve filled your pockets with wriggling treasures, you’ll realize these little guys are more than just collectible cuteness. Each mob you snag opens new crafting doors, letting you turn fireflies into functional gear.
These wriggling treasures open crafting doors—turn fireflies into gear that actually does something.
Here’s what you can craft:
- Bait for the hook — Transform worms and butterflies into fishing ammunition (apprentice bait, 15% power, stacks to 999).
- Glowstick substitutes — Fireflies craft into portable light, 5 per bug, lasting 5 minutes each.
- Terrarium trophies — Bottle your favorites and build that personal museum to display your collection.
- Bestiary completion — Every catch fills entries, unlocking rewards that connect you with the community.
Gathering bugs becomes a way to build something with tangible progression.
Best Early Critters to Catch First
The hunt for your first catches feels like stocking a tackle box before the big fishing trip, so let’s talk about which critters deserve your net’s attention right out the gate.
Grab worms first. Desert and Jungle variants work best, using basic traps set 2-3 blocks deep with active stone mechanisms. They serve double duty as both bait and crafting material. Fireflies swarm forest biomes at night and are easily caught with a net for light sources. Grey Slimes are worth catching since they’re common everywhere, drop gel, and work as passable bait when you need it.
Bunnies hop through grassy areas and make solid starter pets for vanity slots. Grasshoppers and butterflies fill daytime hours, providing cheap fishing fodder or decoration. Each catch builds your collection, your confidence, and your practical understanding of Terraria mechanics.
Fix: Bug Net Missing or Unavailable
You might’ve filled your pockets with worms and fireflies, but what happens when the tool itself goes missing? I’ve been there, staring at my empty inventory, wondering where my trusty Bug Net vanished. Don’t panic; we’ll get you back to catching critters.
When mine goes missing, I check the following:
- Dig through every chest – that sneaky net loves hiding in storage when you’re rushing through multiplayer sessions with friends.
- Scan your inventory slots carefully, especially if you’ve been swapping tools fast, as it slips between rows sometimes.
- Verify your world progression – certain modes like special seeds restrict early item spawns until you hit specific milestones.
- Ask your multiplayer crew – someone might’ve grabbed it by accident, or it dropped during a chaotic fight.
Still empty-handed? Start fresh, or use the console if your group allows it.
