Why Are There Crawling Insects in My House?

Unless uninvited guests arrive carrying a free cake or a large check, you’re probably not a fan. When uninvited visitors have six or more legs and creep across your floor, they’re even less welcome. Nobody wants crawling insects to infest their homes, but how do you keep them out? What causes them in the first place? Why won’t they leave you alone?

First: you keep them from happening by taking preventative measures. Second: the things that cause them are usually easily fixed. Third: they won’t leave you alone because there’s something at your home drawing them in. Today we’ll cover the four most common crawling insect invaders people face. We’ll also arm you with the easy fixes and preventative measures you can take to keep them away.


Ants are one of the most commonly-faced crawling pest problems for both home and business owners. There are over seven hundred different known species in the United States. Of those, there are a few ant varieties that are best known for infesting homes. Those include carpenter ants, pavement ants, odorous house ants, and field ants. Ants typically live in large colonies that work together to build and maintain their nests.

How can I keep ants out of my home?

  • Practice regular perimeter maintenance. Ants like to sneak in through small breaches or holes in your home’s perimeter. Make sure to regularly give your home visual inspections and seal any gaps, cracks, tears, or holes you find as you go. 
  • Keep a watch out for scouts. Single ants are scouts. They come up from their nests to look for food, water, or shelter. Get rid of any solo ants you find so they’re unable to share that information with the rest of their colony.


Despite their name’s disturbing implication that centipedes have one hundred legs, the crawling pests usually don’t. Instead, they have one pair of legs per body segment and can have, on average, between fifteen and seventy total pairs. There are many varieties but they all have flat, elongated bodies. They can measure from one-sixth of an inch to six and a half inches in length. Coloring varies but usually stays between shades of brown, red, and orange.

How can I keep centipedes out of my home?

  • Eliminate their food sources. Centipedes mainly consume other insects. If you’re practicing the rest of the prevention tips listed in this post to keep other pests away, you’re doing well. 
  • Reduce and remove clutter. A tidy home is a home that doesn’t have places for insects to hide. That includes but isn’t limited to centipedes.


Everybody knows about roaches. They’re one of the hardiest creatures on the planet, able to survive in temperatures at both spectrum extremes. The most common pest cockroaches are the German cockroach and the American cockroach. German cockroaches are brownish-black, measuring between ½ and ⅝ inches. American roaches are darker in color and large, measuring between one and two inches. They’re both active throughout the year, are nocturnal, and are drawn to decaying organic matter.

How can I keep roaches out of my home?

  • Wipe up crumbs and spills as soon as you make them. Cockroaches love organic matter. They especially love decaying organic matter. Don’t leave it out for them to find. Wipe up spills and crumbs as soon as they happen and don’t leave dirty dishes in the sink. 
  • Pay special attention to cleanliness. This tip is mentioned more than once, but that’s because it’s important. Insects like cockroaches thrive in unkempt spaces. Take the garbage out regularly, remove grease from the stovetop, and keep your floors clean. These small efforts will go a long way toward preventing roach infestations.


Let’s start out by dispelling a popular earwig myth. No, they won’t actually crawl into your ear while you’re asleep and eat your brain. They won’t even crawl into your ear and take a nap, leaving your brain alone. They won’t go inside your head. What they will do, however, is infest your home. Earwigs are typically a quarter-inch to one inch in length with elongated, flat bodies. Their color can vary between different shades of tan, brown, and red. Their most distinctive physical characteristic are the pincers located on the back of their abdomens.

How can I keep earwigs out of my home?

  • Eliminate the places they like to hide. Earwigs love dead and distressed outdoor spaces. They hide in these spaces and use them as jumping off points for interior infestations. Take away their hiding spots by removing leaf piles, overgrown vegetation, and untended woodpiles. 
  • Make sure your gutters are working properly. Moisture build-up from gutters that are clogged pointing in the wrong direction will draw in earwigs. 
  • Use dehumidifiers. Once more with feeling: earwigs love moisture. Make sure you’re policing the moisture in your home and removing any standing water as you notice it.

If your question is, “Why are there crawling insects in my house?,” the answer is, “Because you’re not keeping them out.” Luckily, with the help of this blog post and other useful tips and tricks, you’ll be able to turn things around.

What are House Centipedes?

House centipedes (Scutigera coleoptrata) are rather unique centipedes. For one thing, they don’t really look like what you picture when you think of a centipede. They look… creepier. More importantly, unlike almost all other centipedes, they can live in your house (hence the name). If you see a centipede in your house, it’s almost certainly a house centipede.

Like most pests, the scariest things about these centipedes are the things you don’t know. If you don’t know what you’re looking at, they look like your worst nightmare. They’re all legs, fangs, and antennae, and they’re fast. Learning about centipedes probably won’t mean you’re not afraid of them at all, but it’ll certainly help. At the very least, you’ll know what that freaky thing you saw darting around your bathroom was. 

Take away a house centipede’s sources of food, shelter, and moisture, and you’ll take away their reason for entering your home. If you want some help removing centipedes from your home, get in touch with Griffin Pest Solutions. We’re always ready to help remove creepy crawlies and keep them from getting in again.

Which Bugs Come Out at Night?

Mosquito at Night

Numerous common household pests are most active during the night. Bed bugs, house centipedes, crickets, and even mosquitoes fall into this category. They emerge in the dark to forage for food, search for mates, and seek sources of moisture. Mosquitoes, in particular, thrive during cooler nighttime temperatures.

It’s no surprise that these “children of the night” can be quite unsettling, especially when they decide to feed on you while you’re trying to sleep. But despite their creepiness, these nocturnal creatures are, in the end, just another type of pest. And like any pest, they can be prevented, controlled, and eliminated. Let’s explore the most common nighttime household pests and what you can do to address them below.

Why Do Bugs Come Out at Night?

Bugs come out at night for a variety of ecological reasons related to temperature, predation, sensory adaptations, food sources, and reproduction. These adaptations allow them to thrive in their respective environments.

Are Bed Bugs Nocturnal?

No surprise here, right? Yes, bed bugs are nocturnal, which means they come out at night. Bed bugs can neither extract the blood they need quickly nor latch onto people forcefully. Instead, they wait until their prey is immobile–like when they’re sleeping–so they can gorge themselves at their leisure. Bed bugs become more active at night both because it’s when their prey is vulnerable, and because the darkness gives them cover.  

How to Protect Yourself From Bed Bugs 

We’ve covered preventing bed bugs a couple of times before. The best thing you can do is to make sure you inspect everything you bring home after traveling. Make sure you don’t bring any unwanted hitchhikers home. Wash and clean your bedding and the bed itself frequently, and inspect it for fecal matter or eggs. Heat kills bed bugs, so if you suspect you have them, throw contaminated items in the dryer. If you have an existing bed bug problem, contact your local exterminator for a professional bed bug treatment.

Why Do Centipedes Come Out at Night?

Centipedes are sneaky daytime hiders who venture out at night for hunting. You might spot them in damp spots or kitchens. They’re drawn to humid, dim, cozy places where they can stay moist and soak up warmth. 

How to Prevent House Centipedes 

Even though they don’t pose any severe harm to humans, they can in fact sting with their two front legs, and they’re just freaky! That’s why preventing them is a good idea. 

To keep them away, reduce indoor moisture, close windows at night, and seal off entry points like gaps between utility lines and walls.

Crickets become active at night - Which pests become more active at night?

Why Are Crickets Most Active at Night?

The reason why crickets are most active at night is because it offers them favorable conditions for feeding, temperature regulation, and mating while minimizing their exposure to daytime predators. With that said, crickets may sound pleasant when they’re outside, but when they’re inside your walls they sound less than pleasant. Crickets are loud, and they love to start chirping right around the time you want to go to sleep, which can get very annoying. They simply do not belong inside your home! 

How to Keep Crickets Away From Your Home

Crickets are attracted to light, heat, humidity, and moisture. Turn off your house lights at night and draw the blinds. Look for and patch up plumbing leaks and other sources of moisture, such as puddling or condensation. Like most other pests, crickets sneak in through gaps in foundations, siding, and window and door frames. Look for places where your noisy foes might squeeze in and seal them up.

Mosquitoes tend to become more active at night - Which pests become more active at night?

Are Mosquitos Most Active at Night?

Mosquitoes are most active during the evening and at night, making them nocturnal or crepuscular insects. They tend to be most active around dusk and dawn, with their activity increasing during the early evening and into the night.

Several factors contribute to their nighttime activity:

  • Temperature: Mosquitoes are cold-blooded insects, and they become more active in the cooler evening hours. Warm temperatures are conducive to their activity.
  • Light Sensitivity: Mosquitoes are attracted to light, and their vision is adapted for low-light conditions. They are less active during daylight when the sun is bright.
  • Feeding Time: Many mosquito species feed on the blood of warm-blooded animals, including humans. These animals are more accessible when they are active, which often coincides with dusk and nighttime when people are outdoors or asleep.
  • Predator Avoidance: Mosquitoes have numerous predators, such as birds and bats, which are more active during the daytime. Being active at night helps mosquitoes avoid some of their natural enemies.

It’s important to note that while mosquitoes are more active at night, there are some species that are active during the day. The behavior of mosquitoes can also be influenced by environmental factors, such as temperature and humidity.

How You Can Prevent Mosquitos in Your Home

To prevent mosquitoes from invading your home, take a few proactive measures. Ensure that all windows and doors have properly fitted screens to keep them out. Remove any standing water sources around your property, as mosquitoes lay their eggs in stagnant water. Using mosquito nets over beds and applying insect repellent on exposed skin can help reduce bites indoors. Also, consider using mosquito traps or citronella candles to deter these pests from entering your living spaces. Regularly maintaining your yard, keeping it well-trimmed and free of debris, can also minimize mosquito breeding grounds.
