What Temperature Do Silverfish Like?

Silverfish are one of the most common household pests. They are nocturnal creatures that typically live in moist environments. Although they prefer damp, cool spots, they can also thrive in hot, dry conditions. In fact, they can even survive in winter, as long as they have sufficient warmth.

Silverfish are about one and a half to three inches long with thin, silvery bodies and tail-like appendages. They have two antennae. The female lays eggs in cracks or crevices. These eggs develop in about three months and then hatch in about two to four months.

Most silverfish species prefer warm, moist environments. Some varieties of silverfish are highly sensitive to temperature changes, while others are more tolerant. For instance, the four-lined silverfish can thrive in a cold climate. However, these pests can’t handle extremely high temperatures.

If you are looking to control silverfish, a dehumidifier can help. This can help maintain a moisture level between 30 and 50 percent. Other techniques include caulking holes and sealant around doors and windows.

Keeping your home clean can also discourage silverfish infestations. You should maintain a weekly cleaning routine that includes vacuuming and dusting. Also, remove bedding and other materials that are considered attractive to silverfish.

A dehumidifier can also help prevent silverfish infestations. Be sure to keep a room temperature between 70 and 80 degrees Fahrenheit. When the temperature rises above 75 degrees, silverfish will begin to mature and become adults.

Using a freezer to kill silverfish can also be helpful. Silverfish are often found in bathrooms and basements.
