Pest problems are a common concern for homeowners and renters in Alberta, but many people rely on outdated or incorrect information when trying to deal with infestations. While some home remedies may seem effective at first, they often fail to address the root cause of the issue. Worse, some myths can make pest problems even harder to control.
In this article, we’ll debunk some of the most common pest control myths and explain what actually works when it comes to eliminating and preventing infestations.
Myth #1: Ultrasonic Pest Repellers Keep Rodents and Insects Away
Many homeowners purchase ultrasonic pest repellers, believing they will drive away rodents and insects by emitting high-frequency sounds. However, research shows that these devices have little to no long-term effect on pest populations.
What Actually Works:
- Sealing cracks and entry points to prevent pests from entering.
- Using properly placed rodent traps for effective control.
- Hiring professional pest control services for severe infestations.

Myth #2: Bed Bugs Only Infest Dirty Homes
A common misconception is that bed bugs only infest dirty or cluttered homes. The truth is that bed bugs do not discriminate—they are drawn to any environment where humans sleep. These pests spread easily through luggage, secondhand furniture, and clothing, making apartments, hotels, and homes all susceptible.
What Actually Works:
- Washing bedding and clothing in hot water and drying on high heat.
- Regularly inspecting mattresses and furniture for signs of infestation.
- Contacting a professional exterminator at the first sign of bed bugs.

Myth #3: Mothballs Repel Mice and Other Pests
Mothballs are often suggested as a DIY rodent repellent, but they are not effective for keeping mice or rats out of homes. Mothballs contain naphthalene, which can be toxic in large amounts, but the concentration in household mothballs is too low to have any impact on rodents.
What Actually Works:
- Using snap traps or live traps to capture mice.
- Sealing all gaps, holes, and vents where rodents could enter.
- Keeping food stored in airtight containers to eliminate attractants.

Myth #4: DIY Vinegar Sprays Kill Ants and Cockroaches
Some people believe that spraying vinegar around the house will eliminate ants and cockroaches. While vinegar can disrupt an ant’s scent trails, it does not kill them or prevent them from returning. Similarly, vinegar has no real effect on cockroach populations.
What Actually Works:
- Identifying the source of the infestation and using bait traps.
- Keeping food sealed and cleaning up spills immediately.
- Sealing cracks and crevices where pests can enter.

Myth #5: Cats are an Effective Way to Control Mice
While cats are natural hunters, they are not a reliable solution for controlling a mouse infestation. Mice reproduce quickly, and one or two cats in a home may not be enough to control an entire colony. Some mice may even learn to avoid areas where a cat is present, leading to an infestation in less obvious places.
What Actually Works:
- Placing multiple traps in areas with high mouse activity.
- Using rodent-proofing techniques to block entry points.
- Consulting professional exterminators for large infestations.
Myth #6: Leaving Lights on at Night Keeps Bugs Away
Some people believe that leaving lights on at night will prevent pests like cockroaches and rodents from coming inside. However, this is a common misconception. While some pests, like cockroaches, prefer dark spaces, others—including mosquitoes and moths—are actually attracted to light.
What Actually Works:
- Keeping outdoor lights away from entry points to prevent attracting insects.
- Using screens and weather stripping on windows and doors.
- Reducing moisture buildup, as many pests are drawn to damp environments.

The Best Way to Handle a Pest Infestation
Many DIY pest control methods provide temporary relief but fail to eliminate the source of the problem. The most effective approach is to:
- Identify the pest and determine its entry points.
- Eliminate attractants, such as food, moisture, and shelter.
- Use targeted solutions, such as traps, exclusion methods, or professional treatments.
- Seek professional pest control services for severe or recurring infestations.
