Home remedies: which of them actually work
An honest look at popular home methods — some aren't useless, just miscast.
Home pest control methods are discussed more readily than commercial products, and it would be wrong to dismiss them out of hand. Some of them really do have an effect — just not the one people expect.
Lavender, cedar, and wormwood against moths. The repellent effect is real, but it works only on adult moths and only while the scent remains strong — in other words, for a few weeks. It has no effect at all on the larvae that damage clothing. It works as a preventive measure in an already clean wardrobe, but not as a way to control an existing infestation.
Boric acid against cockroaches. It works, and that is no myth: it formed the basis of homemade bait long before gels appeared. The problem lies in the dosage and format — a homemade ball dries out, loses its appeal, and works only if a cockroach happens to approach it. Commercial gel solves precisely this problem by combining a stable bait base with delayed action and a chain effect.
Ultrasonic repellers. There is no convincing evidence that they are effective against rodents or insects. An initial response to a new stimulus is possible, but animals quickly become accustomed to it.
Mint and bay leaves against rodents. Mice do dislike strong smells, but a hungry mouse will tolerate them. This does not work as the sole control measure.
The overall conclusion, without condescension: home methods are useful for prevention, before a problem has begun. Once an infestation is present, they create a sense that something is being done while time is lost — and the larger population then becomes more difficult to control.
