The answer to 'silverfish swarms' is that silverfish are small, wingless insects that can sometimes infest homes in large numbers. Common causes of silverfish swarms include damp, humid conditions, plentiful food sources like paper or starch, and lack of natural predators. Symptoms include seeing the insects themselves, especially at night, as well as signs of damage to paper, books, clothing, or other household items.
To address a silverfish infestation, start by identifying and eliminating the root causes. Reduce moisture by fixing leaks, using dehumidifiers, and improving ventilation. Remove food sources by storing paper, books, and other items in airtight containers. You can also try DIY pest control methods like using diatomaceous earth or essential oil sprays. However, for severe or recurring infestations, it's best to call a professional pest control technician who can properly identify the problem and apply targeted, effective treatments.
