When dealing with pests, many people turn to quick fixes or old wives’ tales before calling in professionals. Unfortunately, pest myths often make infestations worse. Believing these misconceptions can waste time, cost money and even allow pests to spread further. We want to clear up some of the most common myths, so you know when to take action.
Myth 1: cats always control mice
Many people think cats will remove a mouse problem. While some cats may hunt, many ignore mice entirely. Even the best hunters cannot reach hidden nests in wall cavities or lofts. Therefore, relying on cats alone will not solve an infestation.

Myth 2: pests only infest dirty homes
Another common pest myth you should know is that they only target unclean properties. However, mice, rats and cockroaches seek food, warmth and shelter wherever they find it. Even spotless kitchens and well-kept offices can attract pests if entry points remain open. So, hygiene is important but it is not the only factor.
Myth 3: DIY sprays remove infestations
You can buy many sprays and traps in shops, but they rarely solve an infestation. These products may kill visible pests, yet hidden colonies remain unaffected. For example, a wasp spray might reduce activity outside, but the nest still survives. Professional pest control uses targeted treatments that reach the root of the problem.
Myth 4: bed bugs are too small to see
Some believe bed bugs are invisible to the eye. In fact, adult bed bugs are about the size of an apple seed. You can spot them on bedding, mattresses and furniture seams. Because infestations spread quickly, professional treatment is essential to eliminate them fully.

Myth 5: ultrasonic devices repel all pests
Plug-in ultrasonic devices are widely advertised, but their results are inconsistent. Some pests may avoid the sound briefly, while others quickly adapt. Relying on these devices can give a false sense of security while infestations worsen.
Why myths are dangerous
Believing pest myths delays effective treatment. While you experiment with sprays, gadgets or “natural cures,” pests continue to breed and spread. Additionally, do-it-yourself methods may expose people or pets to harmful chemicals when used incorrectly.
