How do you try to capture people’s attention?
Loud sounds?
Vibrant visuals?
Dramatic effects?
You see, sometimes, the most effective way to capture attention isn’t with bright colors or flashy graphics but with something that makes you shiver.
Imagine a sound so familiar yet so unsettling, that it lingers in your mind long after you hear it.
In Indonesia, a country rich in folklore and cultural rituals, one deeply rooted fear permeates homes across the archipelago: the fear of cockroaches.
Known locally as katsaridaphobia, this fear isn’t just a quirk; it’s a cultural phenomenon… and it’s exactly this fear that pest control giant Rentokil leveraged to redefine the way Indonesians think about home pest management.
The Challenge: Breaking Through Ineffective Traditions
Despite Rentokil’s established reputation in professional pest control, its home service offerings were largely under the radar.
Many Indonesians relied on quick-fix sprays and homemade remedies, which proved largely ineffective against persistent infestations.
The challenge was clear: Rentokil needed to shift public perception and elevate awareness of its home services, convincing people that real, professional solutions were just a call away.
The stakes were high here. It wasn’t just about selling a service; it was also about changing ingrained habits and cultural attitudes toward pest control.
The Solution: Introducing “The Horroroach”
Enter “The Horroroach” campaign—a masterclass in guerrilla marketing that fused cultural storytelling with a healthy dose of fear.

Oh my…
These familiar tunes were layered with unsettling cockroach sounds, creating a spine-tingling auditory experience that resonated deeply with listeners.
By embedding the fear of cockroaches into culturally significant sounds, the campaign hit a nerve that simple ads could never reach!
-
Audio Broadcasting
These haunting soundscapes weren’t just online novelties; they were also broadcast directly into homes, immersing Indonesians in a familiar yet fear-inducing environment.
This innovative use of audio storytelling transformed cockroaches from mere nuisances into symbols of deep-seated dread, making Rentokil’s solution feel urgent and essential.
-
Social Media Amplification
The campaign extended its reach beyond homes through social media, encouraging people to share their “Horroroach experiences” with the hashtag, #KecoaHoror.
The result?
A viral phenomenon, driving engagement and conversation across Indonesia’s digital landscape!
The Results: Fear That Converts
“The Horroroach” campaign didn’t just generate buzz; it also produced measurable business outcomes:
- Rentokil saw a 300% increase in calls following the campaign launch, signaling a tangible shift in consumer behavior towards professional pest control services.
- #KecoaHoror became the number one trending topic on X, dominating conversations and expanding the campaign’s reach far beyond traditional advertising channels.
- The campaign achieved 8 million total impressions and 2.6 million total audio listeners, ensuring Rentokil’s message reached a wide and diverse audience.
- By integrating local traditions into the campaign, Rentokil repositioned itself as not only an effective service provider but also a brand that understands and respects Indonesian culture.
- The campaign earned multiple accolades, including Bronze at Spikes Asia 2024 (Radio & Audio) and several Silver and Bronze awards at Citra Pariwara 2023 for sound design, casting, and scriptwriting.
Congratulations, Rentokil!

Clearly, “The Horroroach” offers a blueprint for marketers aiming to create campaigns that resonate and convert:
-
Leverage Cultural Insights: Understand the fears, traditions, or habits unique to your audience. Cultural relevance creates emotional resonance that generic campaigns can’t achieve.
-
Transform Everyday Pain Points: Identify familiar annoyances or frustrations and elevate them into compelling narratives. The more relatable your strategy is, the more memorable it will be.
-
Experiment with Mediums: Rentokil’s innovative use of audio shows the power of unconventional storytelling. Consider formats that immerse and engage audiences in unexpected ways.
-
Encourage Participation: Interactive or shareable elements, like hashtags or challenges, can turn passive audiences into active campaign advocates.
-
Align Emotion With Action: Emotional triggers—fear, nostalgia, or humor—can drive behavior. Make sure your creative concept supports the desired audience response, whether that’s a purchase, signup, or awareness shift.
See?
By combining cultural insight, creative risk-taking, and multi-sensory storytelling, marketers can craft campaigns that not only entertain but also reshape perceptions, spark conversation, and drive tangible results.
“The Horroroach” playbook reminds us that marketing isn’t just about promoting a product.
More importantly, it’s about understanding people, speaking their language, and transforming ordinary experiences into unforgettable stories.
About The Dynamic Marketing Communiqué’s
“Fridays: Gorillas of Guerrilla Marketing”
Jay Conrad Levinson (1984) said that Guerrilla Marketing “works because it’s simple to appreciate, easy to execute, and inexpensive.”
Guerrilla Marketing is unconventional.
Looking beyond the traditional ways of advertising, marketers and advertisers need to spice things up in order for their brand to have campaigns that not only make an impact but also stick to their target market’s mind.
Guerrilla Marketing usually aims to have direct contact with consumers.
This type of direct contact should spark an emotional reaction that leads to consumers effectively remembering the brand.
It’s about making a big impression and making that impression last a long time (if not forever).
Guerrilla Marketing can be inexpensive.
The effect of this is being able to create a buzz around the brand, and the strategy used to market it. Almost everything is passed around through word-of-mouth.
Word-of-mouth is one of the greatest outcomes and it usually doesn’t cost anything.
This is every business’ or brand’s dream!
Every Friday, we publish tips, examples, and other useful content on unconventional ways of marketing and promotion.
Learn more about how to grab your target market’s attention and make an amazing first and lasting impression without having to spend a lot of money.
Businesses don’t really need to spend much for a guerrilla campaign. You do not need a big budget to be successful. You just need creativity and a good imagination.
Hope you find this week’s guerrilla marketing insight interesting and helpful.
Stay tuned for next Friday’s “Gorillas of Guerrilla Marketing!”
