Terminator Pest Control can also treat Silverfish outbreaks in your home, however silverfish infestations are fairly uncommon. Silver fish are an unusual insect silver grey in colour and between 12mm. to 25mm. in length. They are flat, and easily able to slip into small gaps and cracks, and are also wingless. They are sensitive to moist damp places, and need 75% humidity to survive. They can survive short periods in lower Humidity. They love warm dark places, with temperatures ranging from 70 to 90 degrees, and while doing rodent jobs in ceilings, I often find them in insulation above built in wardrobes. Silverfish feed on carbohydrates, like pasta, cereals, flour, oats, so keeping that range of food in air tight containers, will certainly help. Silverfish also eat protein such as pet food, and dead insects, but also will eat paper, glue in book bindings, and starch. Other steps the homeowner can take would be using dehumidifiers around damp warm areas.
