House centipedes, also known as Scutigera coleoptrata, are common arthropods that live in homes across temperate climates. They are fast-moving and have long, slender bodies with 15 pairs of legs. House centipedes are nocturnal and prefer dark, moist locations. During the day, they tend to stay hidden in cracks, crevices, and undisturbed areas of a home.
Do house centipedes sleep during the day?
Yes, house centipedes do sleep during the daytime hours. They are naturally nocturnal creatures that are most active at night when hunting for food. During daylight hours, house centipedes will retreat to humid, dark places within a home to rest and sleep.
House centipedes do not have fixed sleep patterns like humans. They can enter periods of rest throughout the day, especially if undisturbed. Their sleep cycles tend to follow circadian rhythms tied to daylight. When it’s bright outside, house centipedes become less active and enter longer rest periods. At night, they wake up to hunt and forage.
Where do house centipedes sleep during the day?
House centipedes sleep in humid, sheltered spots around a home during daylight hours. Some of their favorite places to rest include:
- Underneath furniture
- Inside closets
- Behind baseboards
- Underneath sinks
- Inside bathroom cabinets
- Behind window and door frames
- Inside cracks in walls or floors
- Underneath floor coverings
- Inside attics and crawlspaces
House centipedes require humidity to breathe properly. They prefer resting spots that are dark, secluded, and moist. Cool, quiet corners of a home offer protection from light, heat, noise, and disturbances that might disrupt their sleep.
Do house centipedes hide all day?
For the most part, house centipedes remain hidden away in their daytime resting spots. However, they may cautiously come out on occasion for the following reasons:
- Searching for water if dehydrated
- Looking for new hiding spots
- Disturbed from resting place
- Tracking down food source
- Mating or laying eggs
Even if emerging during daylight, house centipedes will seek out protection and retreat back to seclusion quickly. They can sprint rapidly on their long legs to reach cover.
Do house centipedes eat during the day?
House centipedes are opportunistic eaters and will hunt whenever prey is available. However, they tend to forage and hunt mainly during nighttime hours.
If house centipedes come across easy meals during daylight, such as insects caught in spider webs or pest traps, they may pause to eat. But active hunting is rare. Instead, house centipedes prefer to wait until night to use their fast speed and venom to capture live prey.
What is the behavior of house centipedes during the day?
Here is a summary of typical house centipede behavior patterns during daytime hours:
- Resting – House centipedes spend most of the daylight hours motionless, resting in secluded spots.
- Sleeping – They sleep for large portions of the day, especially in warmer weather when activity levels are lower.
- Hiding – House centipedes stay hidden in cracks and crevices away from light and disturbances.
- Grooming – During brief activity periods, house centipedes will groom their legs and antennae.
- Cautious movement – Any daytime movement is slow and calculated to reach safety quickly.
- Brief feeding – If prey is available, house centipedes may eat during the day.
- Egg-laying – In warm weather, female house centipedes may lay eggs during the day near food sources.
Overall, house centipedes try to conserve energy during daylight hours. They prefer to rest in humid areas and wait for the relative safety of nighttime to hunt.
Do house centipedes come out when it rains during the day?
House centipedes may become slightly more active on rainy days. The humidity and lower daytime temperatures from rain provide favorable conditions for them to search for food and water.
However, heavy rain showers also expose house centipedes to greater dangers. While a light rain shower may elicit some curiosity, daytime downpours likely will keep house centipedes safely hidden away.
Too much rain flooding their hiding spots will force house centipedes to seek drier ground. Once the rain stops, they will quickly return to moist seclusion to avoid exposure during daylight.
How do house centipedes react to light during the day?
House centipedes strongly prefer darkness and avoid bright light. Exposure to light stresses house centipedes and alters their behavior:
- They freeze in place when exposed to light.
- Their activity levels decrease in brightness.
- They scurry quickly to escape illumination.
- They may abandon nests or feeding sites due to light.
- Too much light exposure can kill house centipedes.
If house centipedes are forced into the light, they will dart rapidly back to darkness. Inside homes, daylight from windows quickly drives house centipedes back into cracks and crevices.
Do house centipedes come out in the evening before nightfall?
House centipedes tend to wait until true nightfall before fully coming out of hiding to hunt. Their peak activity levels occur in complete darkness after sunset.
However, as evenings approach, house centipedes may begin stirring in preparation for nighttime activity. Cooler temperatures, lengthening shadows, and fading light provide ideal conditions for house centipedes to slowly emerge.
It is common to spot house centipedes cautiously venturing from their daytime retreats in the hour or two before darkness sets in. While not fully active, they begin tentative scouting as they wait for protective darkness.
Conclusion
In summary, house centipedes are adept at hiding during daylight hours when vision and activity levels are lowered. They prefer humid, enclosed spaces to rest safely. While house centipedes may occasionally emerge if conditions allow, they try to avoid exposure until the protection of night. Their cryptic behavior helps house centipedes survive light-filled days despite their preference for nocturnal hunting.
