New to Catch Bugs? This beginner guide walks you from your first catch in the Grasslands to your first Royal Net (76,000 cash) and your first Secret Tomb run. Catch Bugs is a tycoon, not a shooter — most of your progress comes from the vivarium and net order, not from grinding harder. Follow the route below in order and you will avoid every common new-player mistake.
Once you're in Crawlwood the goal is the Royal Net at 76,000 cash. The Royal Net is the second-cheapest net upgrade and unlocks Moon Hollow comfortably. Most new players see Bone Net videos and try to skip ahead — don't. Royal Net first.
The vivarium is not a late-game system. It unlocks early and starts paying you passive cash from the moment you slot your first bug. The single biggest mistake new Catch Bugs players make is treating the vivarium as something to worry about later — by the time they remember it exists, they have already sold a dozen Rare and Exotic bugs that could have been generating income for hours. Here is exactly how to use the vivarium from minute one.
The moment you catch your first Rare bug in the Grasslands, open your vivarium and slot it. Do not sell it. A Rare bug in the vivarium generates passive cash every hour you are in the game and while you are offline. Over a single real-world night of offline time, that first Rare bug will produce more total cash than its one-time sell price — and it will continue producing every hour after that. Selling it for instant cash buys you a few thousand toward the Fast Net (8,000 cash). Slotting it funds the Fast Net in about 30 minutes of passive income while you keep catching more bugs, and it continues paying after the Fast Net is already bought. The math is not close.

Catch Bugs progression is gated by zone unlocks. Each new zone requires a certain net tier and sometimes a specific condition (time of day, bug count, quest completion). Knowing the unlock order before you start prevents wasting cash on nets that do not open the next zone you need. Here is the full verified zone progression from the starter Grasslands through the May 2026 Prehistoric update locations.

Zone unlock conditions for Grasslands through Desert verified from ProGameGuides, RoUniverse and community YouTube walkthroughs. Bonefern and Scorchden names verified from official Discord #updates message (2026-05-25); unlock requirements, spawn tables and bug names still need in-game verification.
With the Royal Net online, the route opens up. The mid-game is about banking the three Secret Tomb keys and growing the vivarium so it pays your endgame net upgrades for you.

Late-game splits into two grinds: pushing the Scorpion Net (250,000,000) for raw strength, and pushing the April-2026 Desert biome with the new Demon, Nuclear, Black Hole and Dark Matter nets for Zenith and Supreme bugs.
Catch Bugs cash progression follows a predictable curve. At each stage, a specific combination of vivarium income, duplicate selling and targeted grinding produces the fastest route to the next net upgrade. The table below maps each progression stage to its optimal income strategy.
Strategy: catch and sell every Grasslands common bug. 50–80 catches at 100–200 cash each funds the Fast Net in under 15 minutes. Do not slot commons — sell them all. Slot your first Rare immediately when you catch it, but sell all duplicates. Vivarium: 1 slot with your first Rare bug. Avoid: buying lures or saving past 8,000 — the Fast Net is the cheapest jump and unlocks Crawlwood.
Strategy: Crawlwood Exotic bugs sell for significantly more than Grasslands commons. Catch every Crawlwood spawn, slot the first copy of each Exotic, sell duplicates. A full Crawlwood session with a Fast Net typically funds the Royal Net in 45–90 minutes. Vivarium: 2–3 slots with the best Exotics you have caught. Avoid: moving to Moon Hollow before the Royal Net — the catch rate drop on a Fast Net in Moon Hollow wastes time.
Strategy: your vivarium is now your primary income engine. With 4–6 slots of Exotic or higher bugs generating passive income, each 24-hour offline period brings in millions. Grind the Secret Tomb for Undead Scorpion and Thousand Scorpion (both Exotic) to fill remaining slots. Vivarium: all slots filled with Exotic+ bugs. Avoid: buying the Scorpion Net (250M) before the Bone Net (200M) — the Bone Net costs 50M less and is enough to unlock the rest of the endgame. Buy Bone Net first, then save for Scorpion Net afterward.
During weather events, every bug you catch gets a mutation roll that multiplies its sell value. A mutated Exotic can sell for 2–3× its base price. The most efficient cash farming window in Catch Bugs is: Bone Net + matching lure + active weather event + Mutated Nectar Potion (2.5× mutation chance) — all stacked at once. Target the 5-minute window, catch everything you see, and sell mutated duplicates immediately. One well-executed weather window can fund a mid-tier net upgrade by itself. See the mutations and weather events guide for the full cycle timing and lure pairings.
The fastest Catch Bugs progression comes from avoiding the mistakes that experienced players watch beginners make every day. Here are the seven most costly errors, why each one sets you back, and exactly what to do instead.
Selling a Rare bug gives you a one-time cash boost of a few thousand. Slotting it in the vivarium generates that amount every 30–60 minutes forever. Players who sell their first Rare consistently take 2–3× longer to reach the Royal Net.
Bone Net videos on YouTube make the 200M endgame net look like the only goal. The Royal Net at 76,000 cash is the most cost-efficient upgrade in the entire game relative to what it unlocks. Skipping it means attempting Moon Hollow and Deeproot Caves on a Fast Net — the catch rate drop makes the grind 2–3× longer.
Common bugs in the vivarium produce negligible passive income. If you have a Common bug in any slot, replace it with literally anything Rare or higher — the difference in income is substantial. Never leave a Common bug in a slot overnight.
You need all three key bugs in your inventory to re-enter the Secret Tomb at any time. Sell or donate them, and you have to re-catch all three from scratch. Catch a second set for your inventory, slot the first set in the vivarium.
Weather events give every catch a ~1-in-3 mutation chance for 5 minutes, cycling roughly every 45 minutes. Players who ignore the weather indicator miss the highest-value catch windows in the game. Drop what you are doing and move to the matching biome the moment a weather event starts.
The Bone Net gives the highest luck stat in the game and costs 50 million less. For most endgame activities — Secret Tomb runs, cave biome hunting, rare and elusive chasing — the Bone Net's luck advantage matters more than the Scorpion Net's strength. Buy Bone Net first, then save the extra 50M for Scorpion Net afterward.
Codes in Roblox tycoons are one-time events with limited-time rewards. Your vivarium pays out every hour, forever, and compounds as you catch better bugs. Players who wait for a code to fund their progression fall behind players who built the vivarium first. Treat codes as a bonus, not a plan.
Carry three specific bugs at the same time — Crescent Wing Butterfly (Moon Hollow, after 6:30 PM), Wasp Moth (Deeproot Caves), and Spiny Harvestman (Dune Burrow) — then walk into the rocky tunnel between the Potion Traders and the waterfall in Dune Burrow. Inside, talk to Anpu to buy the Bone Net for 200,000,000 cash.
The best net depends on your goal: Bone Net (200M) for luck hunting rares, Scorpion Net (250M) for strength on heavy catches. See the full net comparison, upgrade route and best lure guide on our <a href='/nets/'>best net in Catch Bugs Roblox</a> page.
Every bug placed in your vivarium produces cash automatically while you are online and offline. The rarer the bug, the higher the income, and upgrading the vivarium increases slot count and the global multiplier. Always slot at least one rare or exotic bug before selling it.
