Sealing cracks and gaps in foundations, walls, and windows is a highly effective preventive measure against pest entry into buildings. These small openings can serve as gateways for various pests, including insects and rodents, to infiltrate the interior of a property. By meticulously sealing these potential entry points, property owners significantly reduce the likelihood of infestations, creating a more secure environment.

While natural repellents, planting pest-repelling plants, and rotating furniture can contribute to pest management, they do not provide the same level of physical barrier against entry. Natural repellents may deter some pests temporarily but do not block their access. Similarly, planting certain plants near entrances may have limited effectiveness and often requires specific conditions to work effectively. Regularly rotating furniture is primarily aimed at cleanliness and may help in spotting pest signs, but it does not physically prevent pests from entering in the first place. Thus, sealing cracks and gaps stands out as a crucial and proactive strategy in pest prevention.
