Beastmaster
* 
Reactive Armor is very effective against Beastmaster's summons during laning stage and entire game.
* Timbersaw can quickly clear Beastmaster's summons with his nukes.
* 
Lotus Orb item for Timbersaw can difficult for Primal Roar.
Broodmother
* Reactive Armor prevents Broodmother's spiderlings from being able to effectively harass Timbersaw in the lane.
* 
Timber Chain's high mobility makes Silken Bola's slow irrelevant, unless Broodmother already bought her Orchid.
* Silken Bola's miss chance doesnt affect Rizzrack that much because he does not rely on his autoattacks much.
* Lotus Orb items for Timbersaw make Silken Bola useless.
* Timbersaw's abilities can destroy any trees that Broodmother attempts to hide in and his AoE abilities can quickly clear her Spiderlings.
Additional:
* Spiderlings deal almost no damage against Reactive Armor. They also die quickly from Timbersaw's AoE abilities.
* Broodmother has no mobility ability except the movement speed buff from 
Spin Web, allowing Timbersaw to easily escape her 
Silken Bola with Timber Chain.

Phantom Lancer by their nature offer very good target for Splinter Blast and Winter's Curse.
Beastmaster
* Heroes who summon multiple units that are not spell immune. Nature's Prophet,
Lycan,
Beastmaster
Broodmother
* Your AoE abilities should make quick work of her spiderlings.
Beastmaster

Warlock, 
Wraith King.
Broodmother
* 
Ion Shell zones out Broodmother in the laning phase, and can kill her spiderlings if used on one Spiderling in a group.

Broodmother
* 
X Marks the Spot prevents Broodmother from escaping.
* 
Tidebringer can clear Broodmother's spiders if they get in range.
Additional:
* Kunkka's entire kit is great for taking out multiple units at once.
* Tidebringer's cleave will split through a wave of spiderlings.

* Even being initiated by Primal Roar, 
Borrowed Time can make Abaddon extremely difficult to kill.
Broodmother
* 
Echo Stomp can impede Broodmother's ability to push towers due to its low cooldown and long sleep duration.
* 
Astral Spirit can provide Elder Titan large amounts of damage, armor, and movement speed from her spiderlings.
* 
Natural Order negates Broodmother and her spiderling's base armor and magic resistance, increasing most damage dealt to them.
Broodmother
* Broodmother and her Spiderlings need to be very careful during the laning stage against Jakiro, as Jakiro can take down Broodmother's Spiderlings, preventing her from pushing as well as gaining a good amount of gold.
Broodmother
* 
Burrowstrike can be used as an escape or initiation against Broodmother.
* 
Sand Storm quickly kills any spiderlings caught inside if Sand King can manage to stun them.
Additional:
* Caustic Finale allows Sand King to easily kill Broodmother's Spiderlings throughout the game.
* Sand King can usually catch a split pushing Broodmother with 
Blink Dagger and Burrowstrike.
Broodmother
* 
Death Pulse can easily wipe out Broodmother's spiderlings if they're too close while also offering Necrophos a source of regeneration for Broodmother's harass in lane.
* 
Ghost Shroud prevents Broodmother or her spiderlings from damaging Necrophos temporarily until Broodmother buys 
Nullifieror 
Revenant's Brooch.
* 
Heartstopper Aura will regenerate lost health and mana for every spiderling or spiderite Necrophos manages to kill.
Broodmother
* 
Ice Blast prevents 
Insatiable Hunger lifesteal, Spin Web regeneration and quickly kills spiderlings.
Broodmother
* While Broodmother can hide in the trees with Spin Web, Primal Beast's ability to trample trees down can give him an edge in catching her.
* Insatiable Hunger will not do much vs Primal Beast's onslaught of disables.
* While Silken Bola can slow Primal Beast down, it's not enough to stop Trample from doing more damage than Broodmother can do back.
* 
Spawn Spiderlings will be destroyed by Onslaught and Trample very easily.
Broodmother

* 
Laguna Blade offers extensive damage that can kill Broodmother early on or before she is able to use Insatiable Hunger in attempts to salvage a fight.
Broodmother
* Quill Spray destroys spiderlings, and hits Broodmother even when she's regenerating in her webs. This makes Bristleback one of her hardest counters in lane.
Additional:
* 
Bristleback reduces most of Broodmother's and her spiderlings' damage.
* 
Quill Spray will hit any spiders in its proximity, hindering Broodmother's fighting and farming capabilities.
Broodmother
* 
Overwhelming Odds's damage stacks with each enemy unit in its radius. If this hits Broodmother and a large number of spiders it can deal significant amounts of damage.
* 
Moment of Courage has a high chance to proc if Broodmother and all of her spiders are attacking her.
* 
Duel can keep Broodmother in place long enough for Legion's team to kill her.
Additional:
* Overwhelming Odds is great at killing many stacked up spiderlings, thus giving Legion Commander a large buff.
* Duel is a reliable way to lock down Broodmother, preventing her from running into the treeline.
Broodmother
* Spiderlings are a good source of farm for 
Necromastery and can be quickly killed with 
Shadowraze.
* Shadow Fiend is a natural 
Black King Bar carrier, protecting him from any of Broodmother's abilities.
* 
Requiem of Souls combined with 
Eul's Scepter of Divinity can potentially kill Broodmother before she gets a Black King Bar.
Broodmother
* Alchemist can easily farm Spiderlings with Acid Spray and Greevil's Greed.
* Alchemist's Chemical Rage nullifies Broodmother's Insatiable Hunger
Additional:
* 
Greevil's Greed makes Broodmother’s spiderlings far more valuable to Alchemist making it important that he does farm them as opposed to other heroes where the spider's bounties are negligible.
* 
Acid Spray makes it difficult to attack Alchemist in lane without losing some spiderlings to the damage over time, potentially giving him farm he wouldn't have otherwise.

Storm Spirit, 
Magnus, 
Pangolier.
Broodmother
* 
Ball Lightning and 
Electric Vortex will catch Broodmother before she has a chance to retreat, and is able to catch her through the trees.
* Conversely, Ball Lightning also allows him to easily escape Broodmother, as she has no way to prevent him from using it before getting 
Orchid Malevolence.
Beastmaster
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: Storm Spirit, 
Ember Spirit, 
Queen of Pain.
Beastmaster
* Heroes with AoE abilities are a bane to Beastmaster's summons: Storm Spirit, Magnus, Pangolier.

Luna, 
Sniper, 
Troll Warlord, Weaver, 
Clinkz.
Broodmother
* 
Earthbind prevents Broodmother from escaping Meepo's attacks.
* 
Poof will quickly clear any nearby spiders.
* Broodmother often picks off single target heroes. With Meepo's 
Divided We Stand, it gets a lot harder once every Meepo Poofs in.
Beastmaster
* Because only one clone needs to be killed in order to kill Meepo, heroes that excel at singling out enemies can also be a detriment to him, such as Batrider, Beastmaster, Pudge and 
Clockwerk.
Beastmaster
* 
False Promise effectively nullifies Primal Roar's single-target initiation on allies.
* 
Purifying Flames kills Beastmaster's Hawk instantly and Boar with two casts.
Broodmother
* Oracle cannot easily deal with swarms of units, making him weak against heroes like Phantom Lancer or Broodmother.
Broodmother
* Berserker's Call can catch Broodmother in her web, as well as groups of spiderlings. This is particularly effective when Broodmother attempts to push towers with her spiderlings.
* Counter Helix destroys spiderlings very quickly and earns Axe a good deal of gold.
Additional:
* 
Berserker's Call forces Broodmother and her spiderlings to attack, allowing for large amounts of pure damage to be done through 
Counter Helix.
Beastmaster
* Long lockdown is a great way to deal with Axe to prevent Berserker's Call from being used, heroes such as Legion Commander, Beastmaster and 
Primal Beast are good examples of this.
Broodmother
* 
Sleight of Fist keeps Ember Spirit invulnerable until he hits every unit in its area of effect allowing him to stall for large amounts of time against Broodmother and her large amounts of spiderlings, or potentially damaging them enough if equipped with an item to improve wave clearing such as 
Battle Fury or 
Maelstrom to prevent her pushes entirely.
* 
Flame Guard will damage any of Broodmother's spiders in an area, deterring her from attempting to kill him. It can also be used during Sleight of Fist to amplify damage done.
* 
Fire Remnant allows Ember Spirit an escape from Broodmother that is unaffected by her Incapacitating Bite.
Beastmaster
* Heroes who rely on high mobility are especially vulnerable to Primal Roar: Storm Spirit, Ember Spirit, Queen of Pain.
Beastmaster
* Wraith King's lack of area of effect spells makes him easily overwhelmed by Beastmaster's summons.
Broodmother
* Broodmother can easily clear Wraith King's skeletons with Spawn Spiderlings and summon spiderlings in their place.
* With 
Diffusal Blade, Broodmother can prevent Wraith King from reincarnating unless Wraith King has his Aghanim's Shard.
Beastmaster
* Wild Axes, Primal Roar and 
Drums of Slom can deal high damage to Chen and clear waves of his creeps.
* Even though Chen can take control of the Boar from 
Call of the Wild Boar at any time with 
Holy Persuasion, which could put Beastmaster in a disadvantage against Chen. Skilled Beastmaster can buy 
Helm of the Overlord to regain control of it to counter this problem.
* Smart Beastmaster can also buy 
Bloodthorn to prevent Chen from taking control of the Boar from Call of the Wild Boar and make Chen more vulnerable to Beastmaster.
Broodmother
* Chen's low mobility and lack of AoE abilities makes him an easy target for Broodmother and her Spiderlings.
* Broodmother can easily pick off Chen's creeps with Spawn Spiderlings, and by ambushing them through terrain in her web.
Additional:
* Chen has no area-of-effect spells to deal with Broodmother's spiderlings and must rely on his creeps to take care of them.
* Spawn Spiderlings can kill Chen's creeps and spawn spiderlings in their place.
* Spin Web allows Broodmother to disrupt Chen's jungling.
* Silken Bola will cause Chen and his creeps's attack to miss more often while also making them more vulnerable to magical damage, especially if Broodmother picks 400 AoE Silken Bola talent.
* Broodmother is a natural Bloodthorn wielder, which will allow her to prevent Chen from trying to save himself with 
Hand of God while also making him more vulnerable to damage, and when combined with Insatiable Hunger, it will spell a quick and certain death for Chen. Bloodthorn's passive ability will also reduce any spell damage Chen tries to inflict with his creeps.
* 
Spinner's Snare from 
Aghanim's Scepter allows Broodmother to create invisible lines on her webs from Spin Web that will root Chen and his creeps, deal damage over time to them and reveal them if they unwittingly steps on them, disrupting Chen's jungling even more while also alerting Broodmother on their attempts to ambush her and her allies.
Beastmaster
* Heroes with disables that ignore spell immunity will render Phantom Assassin quite useless in teamfights throughout the game: Axe, Enigma, 
Vengeful Spirit, 
Doom, Bane, Beastmaster, Pudge, Medusa, Warlock.
Broodmother
* Phantom Assassin's single target abilities make her very helpless against swarms of Spiderlings without Battle Fury.
* Because Phantom Assassin is always reliant on critical strikes, Broodmother will usually have enough time to use Spin Web to save herself.
* Silken Bola can cripple Phantom Assassin greatly due to her being 100% reliant on physical attacks.

Beastmaster
* The Hawk can easily find Monkey King while he is sitting on a tree.
* Wild Axes can knock out Monkey King from tree.
* Boars drastically reduce Monkey King's attack speed, making it harder for him to gain 
Jingu Mastery stacks.

* 
Call of the Wild Hawk can scout Monkey King when he is perched on top of trees.
* Primal Roar can stun Monkey King for a lengthy duration even with spell immunity.
Broodmother
* Heroes with blind of some sort can be a bad choice for Monkey King to go on: Broodmother, 
Riki, 
Keeper of the Light.
Beastmaster
* Long ranged disables, especially those that pierce spell immunity, cancel Black Hole: Beastmaster's Primal Roar, Bane's 
Fiend's Grip, 
Faceless Void's 
Chronosphere, Magnus's 
Reverse Polarity, Axe's Berserker's Call, Pudge's
Meat Hook.
Broodmother
* Broodmother can kill Enigma's Eidolons with Spawn Spiderlings, and spawn her spiderlings in their place. But remember that Enigma can do the same to Broodmother's spiderlings with 
Demonic Conversion and 
Midnight Pulse.
* Without the protection from Black King Bar, Broodmother can cancel Enigma's 
Black Hole with Bloodthorn and make him more vulnerable to damage. Broodmother can also buy 
Abyssal Blade to cancel Enigma's Black Hole even through Black King Bar.
* Silken Bola causes Enigma's attacks to miss a lot and renders him more vulnerable to magical damage. And if Broodmother takes 400 AoE Silken Bola, then she will be able to use to cause Enigma's Eidolons to miss their attacks as well. In addition, Enigma does not like to buy items to provide him true strike such as Bloodthorn, 
Monkey King Bar, 
Witch Blade and it's upgrade Revenant's Brooch.
* If Broodmother is lucky enough to survive being trapped in Black Hole, she will be able to recover her lost health with Insatiable Hunger.
* Aghanim's Scepter gives Broodmother access to Spinner's Snare, which allows her to create invisible lines on her webs from Spin Web that will root Enigma, deal damage over time to Enigma and reveal Enigma if he unwittingly steps on them, disrupting his attempts to initiate with Black Hole, prevent him from using Blink Dagger, while also alerting Broodmother on his attempts to ambush her and her allies.
Additional:
* Broodmother can kill Enigma's Eidolons with Spawn Spiderlings, and spawn her spiderlings in their place. And Enigma can't use 
Demonic Summoning to instantly kill spiderlings at once.
* Without the protection from Black King Bar, Broodmother can cancel Enigma's Black Hole with Bloodthorn and make him more vulnerable to damage. Broodmother can also buy Abyssal Blade to cancel Enigma's Black Hole even through Black King Bar.
* Silken Bola causes Enigma's attacks to miss a lot and renders him more vulnerable to magical damage. And if Broodmother takes 400 AoE Silken Bola, then she will be able to use to cause Enigma's Eidolons to miss their attacks as well. In addition, Enigma does not like to buy items to provide him true strike such as Bloodthorn, Monkey King Bar, Witch Blade and it's upgrade Revenant's Brooch.
* If Broodmother is lucky enough to survive being trapped in Black Hole, she will be able to recover her lost health with Insatiable Hunger.

Beastmaster
* Illusion or summon-based heroes can be a problem to Viper due to his lack of AoE damage: Naga Siren, Phantom Lancer, Beastmaster

* Broodmother can bring Viper down quickly with Insatiable Hunger activated.
Beastmaster
* Heroes with summons or illusions can counter Flux, such as Beastmaster , 
Chen, or 
Shadow Demon.
Broodmother
* None of Arc Warden's abilities are very effective against Broodmother and her spiderlings.

* Arc Warden has no innate disables to stop Broodmother from lifestealing with Insatiable Hunger and shredding through his relatively lower armor.
Beastmaster
* Heroes with illusions and summons can manfight Night Stalker: 
Terrorblade, Beastmaster, Broodmother.
Broodmother

Beastmaster
* Attacks from Boars and the attack speed boost from Inner Beast will quickly wear down 
Refraction.
Broodmother
* Though Mirana can clear waves of Broodmother's spiderlings with 
Starstorm, Broodmother will often stick with her spiderlings from Spawn Spiderlings, which in combination with the huge speed provided by Spin Web can make it hard for Mirana to hit her with 
Sacred Arrow.
* Broodmother commonly buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to prevent Mirana from escaping with both, 
Leap and 
Moonlight Shadow and from fighting back with Starstorm.
Additional:
* Though Mirana can clear waves of Broodmother's spiderlings with Starstorm, Broodmother will often stick with her spiderlings from Spawn Spiderlings, which in combination with the huge speed provided by Spin Web can make it hard for Mirana to hit her with Sacred Arrow.
* Broodmother commonly buys Orchid Malevolence and it's upgrade Bloodthorn, which allows her to prevent Mirana from escaping with both, Leap and Moonlight Shadow and from fighting back with Starstorm.
Broodmother
* Drow Ranger's lack of mobility makes her easy prey for Broodmother and her Spiderlings.
Broodmother
* Sniper is completely helpless against Broodmother's abilities, and can be seriously damaged by Spiderlings in lane, especially when 
Shrapnel is on cooldown.

* Wild Axes destroys large amounts of trees specially upgraded with Aghanim's Scepter,
Beastmaster
* Primal Roar and the slow from Boars makes kiting Ursa very easy.
Broodmother

Beastmaster
* Inner Beast helps Beastmaster's team destroy

Beastmaster
* Primal Roar allows Beastmaster to keep Lycan in place after he used his Shapeshift.
Broodmother
* Spiderlings melt away 
Living Armor almost instantly.
* The vision from 
Eyes In The Forest may prove dangerous for Broodmother, however.
Broodmother
* Heroes who can summon illusions and summons because Terrorblade has no abilities to deal with multiple enemies at once outside Reflection: Shadow Shaman, Naga Siren, Broodmother, Lycan, Enigma, Chaos Knight, Phantom Lancer, Shadow Demon, 
Dark Seer, Nature's Prophet, 
Invoker, Morphling, Visage, Grimstroke with Aghanim's Scepter.
Broodmother
* Support heroes with low mobility can be slowed further by Incapacitating Bite, and swarmed by Spiderlings for an easy kill: Shadow Shaman, Visage, 
Dazzle, 
Rubick, 
Lich.
Broodmother
* Heroes with summons like Broodmother, Enigma, Nature's Prophet; or illusions, like Naga Siren, Terrorblade are effective at keeping the choke points and rune spawns safe from Proximity Mines.
Broodmother
* Clockwerk lacks burst damage, and that makes him vulnerable to heroes who can recover themselves and turn the fight around to their advantage after Clockwerk finishes his initiation. Additionally, Clockwerk hates buying 
Dagon and 
Ethereal Blade, which are the only itmes that can help him deal with heroes who can recover themselves and turn the fight around to their advantage: Faceless Void, Terrorblade, 
Ursa, Weaver, Broodmother, Slark, Abaddon, Wraith King, 
Lifestealer.
Beastmaster

Jakiro with Aghanim's Scepter upgraded 
Macropyre.
Beastmaster

Beastmaster
* Heroes with Linken's Sphere as core item: Weaver, Morphling, Medusa.
Broodmother
* Webbed areas can be used to hit and run, covering distance hastily weakening her on the way and initiating ganks.
* Even though Medusa can hunt down Spiderlings easily when given enough range, Silken Bola will cause her attacks to miss and get her swarmed in no time.
* Medusa usually does not build a Black King Bar to benefit from 
Mana Shield fully while Broodmother can fit a Diffusal Blade to burn away all of Medusa's mana.
Additional:
* Spin Web will allow Broodmother to pick her own fights and sometimes slip away to ambush Medusa.
* Though Medusa's Split Shot and Mystic Snake can help Medusa deal with Broodmother's spiderlings, Broodmother will create too much of them for her to handle, allowing her to outnumber Medusa's targets from Split Shot and shield her team in process.
Beastmaster
* 
Untouchable negates Inner Beast's attack speed bonus, making her hard to kill even if stunned by Primal Roar.
* Enchantress can also take control of Beastmaster's summons.
Additional:
* 
Enchant can control Beastmaster's boars, mitigating his effectiveness during the laning stage and teamfights.
Broodmother
* Enchantress's lack of AoE abilities allows Broodmother to swarm her with Spiderlings.
* Spawn Spiderlings can kill enchanted creeps.
* However, keep in mind that Untouchable makes it harder for Brood to actually hit Enchantress, even if Broodmother is spell immune.
Additional:
* Enchantress can be easily overwhelmed with Broodmother's spiderlings from Spawn Spiderlings and Enchantress can only control one of them with Enchant and she has no good waveclear (Spawn Spiderlings can also kill creeps controlled with Enchant).
* However, Untouchable's attack speed reduction can make it difficult for Broodmother to kill Enchantress even with any form of spell immunity.
Broodmother
* Tiny can quickly clear Spiderlings with his active abilities and cleave.
Beastmaster
* Primal Roar and the slow from Boars make kiting Tiny very easy.
Broodmother
* 
Great Cleave cleans up Spiderlings quicker than most spells, as it ignores their magic resistance.
* Sven is a natural Black King Bar carrier, protecting him from Silken Bola, Spawn Spiderlings and Orchid Malevolence.
*
