Finding house centipedes in your home can be unsettling, but discovering their eggs means you’re dealing with an established population. These fast-moving arthropods with their 15 pairs of long legs aren’t just occasional visitors – they’re likely breeding somewhere in your house.
Over my four years as a registered technician, I’ve seen countless homeowners surprised to learn that house centipede eggs are often hiding in plain sight. Our family business has been serving the DMV area for over 50 years, and centipede issues have become increasingly common as homes provide the perfect breeding environment.
Understanding house centipede reproduction is crucial because these creatures can live up to 6 years and produce hundreds of offspring. Additionally, their presence often indicates you have other pest problems they’re feeding on.
⚠️ Infestation Warning: A single surviving female house centipede can lay up to 150 eggs in one season. Finding even one young centipede with 4-7 pairs of legs means you have an active breeding population that’s been established for months.
House centipede reproduction follows a unique pattern that homeowners should understand. Males don’t mate directly with females. Instead, they perform a courtship “dance” around the female, tapping and moving in specific patterns.
When the female is receptive, she picks up a spermatophore (sperm packet) that the male deposits. The female stores this sperm until she’s ready to lay her eggs, typically during spring and early summer when indoor temperatures reach the mid-60°F range.
Individual females lay between 60-150 eggs over a season, which means even one female surviving winter indoors can create a significant population problem.
According to the University of Arkansas Arthropod Museum, house centipede reproductive capacity varies significantly based on environmental conditions. Studies show females can lay an average of 63 eggs per reproductive cycle, with some producing up to 150 eggs when conditions are optimal. The museum’s research indicates that indoor environments with stable temperatures between 65-75°F provide ideal conditions for multiple reproductive cycles per year.
House centipede eggs are incredibly small and difficult to spot. They’re about the size of a pinhead (roughly 1 millimeter) and appear glossy white to translucent. The eggs are often coated with maternal secretions and debris, making them blend into their surroundings.
Because of their tiny size and protective coating, house centipede eggs are easily overlooked during routine cleaning. They don’t have the waxy coating that many insect eggs possess, which means they must stay in humid environments to prevent drying out.
In my experience inspecting homes, I’ve found that homeowners typically discover the young centipedes before they ever notice the eggs themselves. The eggs are simply too small and well-hidden to catch most people’s attention.
House centipede eggs are always deposited in humid, protected locations. Female centipedes specifically choose sites that will keep their eggs moist throughout development. Here are the most common egg-laying locations I’ve encountered:
The University of California IPM research confirms that all egg sites share one characteristic: they’re humid and shaded to prevent egg desiccation.
House centipede eggs take several weeks to several months to develop, depending on temperature. At typical indoor temperatures around 72°F, eggs hatch in 2-4 weeks. However, in cooler basements below 65°F, development can take 8-12 weeks.
Interestingly, female house centipedes display parental care behavior that’s unusual among household arthropods. According to Animal Diversity Web, mothers remain with their egg clutches for approximately 14 days after hatching to protect the young from mites and springtails.
This extended development time means that by the time you notice young centipedes, the eggs were laid months earlier. This is why finding even small centipedes indicates an established breeding population rather than recent invaders.
House centipede development is fascinating and helps explain why populations can grow so quickly. When house centipede eggs hatch, the tiny larvae emerge with only 4 pairs of legs – quite different from the 15 pairs adults possess.
Young centipedes add legs through a series of molts:
After reaching 15 pairs of legs, centipedes continue molting four more times before becoming reproductive adults. This entire process takes 2-3 years under typical Mid-Atlantic indoor conditions.
Once mature, house centipedes can live 5-6 years according to University of Florida IFAS Extension. This exceptional longevity for household arthropods means generations overlap, allowing populations to build steadily over time.
Discovering house centipede eggs or young centipedes indicates two significant issues. First, you have an established population that’s been breeding in your home for months or years. Second, you likely have other pest problems providing food for the centipedes.
House centipedes are exclusively predatory. They don’t eat plant material or household crumbs – they hunt other arthropods. Their common prey includes:
A surge in centipede activity almost always follows an increase in their prey populations. During my inspections, I typically find that addressing the underlying pest issues is crucial for long-term centipede control.
The most effective approach to house centipede eggs focuses on eliminating suitable egg-laying environments. Because eggs require consistent moisture, controlling humidity is your primary weapon.
Maintain indoor relative humidity below 45% whenever possible. In the DMV area’s humid climate, this often requires:
Sealing potential egg-laying sites prevents centipedes from accessing prime breeding locations:
Additionally, similar to the moisture control strategies discussed in our termite mud tubes guide, eliminating conducive conditions prevents multiple pest problems simultaneously.
Professional treatment of house centipede eggs requires understanding their biology and development patterns. At Better Termite & Pest Control, our approach targets both eggs and the conditions that support them.
Our registered technicians use flashlights and mirrors to examine cracks as small as 1 millimeter around sill plates, baseboards, and foundation joints. We also lift stored materials, inspect potted plants, and check behind appliances in damp areas.
Finding even one young centipede with only 4-7 pairs of legs signals active reproduction. These discoveries guide our treatment strategy and follow-up scheduling.
Effective treatment combines multiple approaches:
Because house centipede eggs are relatively resistant to contact insecticides, combining chemical control with habitat modification is essential for success.
Preventing future house centipede egg-laying requires ongoing attention to the conditions that attract these arthropods. Based on our 50+ years serving the DMV area, successful prevention focuses on three key areas.
First, maintain consistent moisture control throughout your home. This means addressing not just obvious leaks, but also condensation issues, poor ventilation, and seasonal humidity changes that create micro-environments suitable for egg development.
Second, implement integrated pest management for the insects and arthropods that centipedes prey upon. Controlling silverfish, spiders, and oriental roaches removes the food sources that support centipede populations.
Finally, regular professional monitoring helps detect early signs of centipede activity before populations become established. Our quarterly pest control plans include inspection of prime egg-laying sites and treatment adjustments based on seasonal patterns.
Understanding the connection between different household pests – much like the relationship explored in our house centipede vs silverfish comparison – helps create comprehensive prevention strategies that address multiple issues simultaneously.
If you’re dealing with house centipede eggs or want to prevent future infestations, professional inspection and treatment provide the most reliable results. Our family has been protecting DMV homes from centipedes and other household pests for over five decades, and we understand the unique challenges posed by our region’s climate and housing types.

House centipede eggs are tiny, about 1 millimeter in size, and appear glossy white to translucent. They’re often coated with maternal secretions and debris, making them very difficult to spot with the naked eye. Because they’re so small and well-camouflaged, most homeowners discover young centipedes before they ever see the actual eggs.
House centipedes lay eggs in humid, protected areas like hairline cracks behind baseboards, under basement slab edges, in houseplant soil, and near plumbing in bathrooms or kitchens. They specifically choose locations that stay moist because their eggs don’t have waxy coatings and will dry out in low-humidity environments.
House centipede eggs typically hatch in 2-4 weeks at normal indoor temperatures around 72°F. In cooler areas like basements below 65°F, development can take 8-12 weeks. Temperature is the main factor affecting how quickly the eggs develop into larvae.
Female house centipedes lay between 60-150 eggs over a breeding season, with an average of about 63 eggs per female. They don’t lay all eggs at once but deposit them in scattered locations throughout spring and early summer when conditions are favorable.
Yes, finding house centipede eggs or young centipedes indicates an established population that’s been breeding in your home for months. It means at least one female survived winter indoors and found suitable conditions to reproduce. This suggests you have ongoing moisture issues and likely other pest problems that provide food for the centipedes.
The best prevention focuses on moisture control – maintain indoor humidity below 45%, fix leaks, improve ventilation, and seal cracks where eggs might be deposited. Also address other pest problems since centipedes need prey to survive and reproduce. Regular professional inspection helps catch issues before populations become established.
House centipede eggs can survive winter if they’re in protected indoor locations with stable temperatures and humidity. Eggs laid in late fall may overwinter and hatch in spring when temperatures warm up. This is one reason why indoor centipede populations can persist year-round in heated homes.
House centipede eggs themselves are not harmful to humans – they’re simply too small to cause any direct problems. However, their presence indicates conditions in your home that support various pest populations, including the prey species that centipedes feed on, which may include more problematic pests.
