What’s That Bug? A Quick Guide to Common Household Pests (and What Attracts Them)

Uninvited guests in your home don’t always knock—some crawl, scurry, or fly in without a sound. Whether you’ve noticed something skittering across the floor or found mysterious damage to food or furniture, pest activity often begins before you even know it. To help you get ahead of the problem, here’s a conversational breakdown of the most common pests, what draws them into your space, and what you can do about it.


Q: I keep finding small bugs near my windows. What could they be?

That’s a classic sign of seasonal invaders. Small insects like ants, cluster flies, or even gnats are drawn to the warmth and light coming through glass. In the spring and fall, they may sneak in through window cracks looking for shelter or food. Tiny entry points in window sashes, screens, or weather stripping can become easy access routes.

The key to preventing these intrusions is sealing gaps with silicone caulk, replacing worn screens, and avoiding moisture build-up on sills. If you’re already seeing more than a few bugs, it might be time to consult a pest control expert to stop the problem before it spreads.


Q: I heard scurrying in the ceiling. Could it be rodents?

Absolutely. Mice and rats love attics, crawlspaces, and wall voids because they provide safety and insulation. Once inside, they can multiply quickly. Rodents are drawn to warmth, food sources like dry pantry goods, and even pet food left out overnight.

Rodent infestations aren’t just gross—they can also lead to serious property damage. Chewed wiring, insulation damage, and contamination from droppings are common side effects. It’s often necessary to work with a rodent exterminator who can assess hidden access points and prevent reinfestation.


Q: Are cockroaches only found in dirty homes?

Not at all! This is one of the biggest myths in pest control. Cockroaches are survivalists and opportunists. While they do thrive in unclean conditions, even tidy homes can have them. Warm, damp areas like behind the fridge, under sinks, or in basements provide perfect shelter.

They’re mostly nocturnal, so seeing one during the day is often a sign of a larger infestation. Eliminating leaks, cleaning up food crumbs, and securing garbage containers are solid first steps. For larger issues, professional pest control services—such as those provided by companies like Modern Pest Solutions—are recommended to target both the bugs and their eggs.


Q: What’s the difference between an ant and a termite?

They may look similar at first glance, but their habits—and the damage they do—are very different. Ants are more surface-oriented, often appearing in lines near food sources. Termites, on the other hand, prefer to remain hidden and can chew through wood, drywall, and insulation quietly and destructively.

If you’re finding small piles of sawdust, hollow-sounding wood, or discolored drywall, those are red flags for termite activity. Early intervention is crucial, as termite damage can be both structurally dangerous and expensive to fix.


Q: My pet keeps scratching, but I don’t see fleas. Could pests still be the problem?

Definitely. Fleas can hide in carpet fibers, bedding, and furniture—making them hard to detect in the early stages. Plus, their eggs and larvae may not be immediately visible. It’s also worth noting that other pests, like mites or even bed bugs, can cause itching for pets and humans alike.

Deep cleaning your home and bathing pets are good starting points, but infestations often require the help of pest control professionals. If symptoms persist, scheduling an inspection is a safe bet.


Q: How do pests get into clean, modern homes?

Even the most modern construction isn’t immune. Bugs and rodents can enter through:

  • Tiny foundation cracks
  • Gaps in door seals
  • Roof vents
  • Dryer and plumbing exhaust lines
  • Open chimneys or soffits

Many pests are incredibly small or agile—cockroaches can squeeze through openings the width of a dime. That’s why integrated pest control, which combines prevention and treatment, is so important.


Q: What attracts pests into my home in the first place?

Here’s what pests are looking for:

  • Food: Crumbs, spills, uncovered trash, and pantry items.
  • Water: Leaking faucets, pet water bowls, or standing moisture in bathrooms or basements.
  • Shelter: Insulated walls, cardboard boxes, storage bins, and fabric furniture are all appealing hiding spots.
  • Entry Points: Any opening the size of a nickel or smaller is fair game.

Understanding what’s attracting pests gives you the advantage of removing the incentive for them to stay.


Q: How often should I get professional pest control treatments?

It depends on your environment. For homes in wooded or humid areas, quarterly treatments can be a proactive approach. If you’ve dealt with a serious issue in the past—like termites, cockroaches, or rodents—more frequent inspections might be warranted.

Whether you’re managing a single-family home or an office space, ongoing protection can prevent small issues from turning into major headaches. That’s why businesses like Modern Pest Solutions often recommend custom pest control plans tailored to each property.


Q: Are over-the-counter sprays effective?

They can provide temporary relief but typically don’t address the full problem. For example:

  • Sprays may not kill eggs or larvae
  • Surface sprays don’t treat inside wall cavities
  • DIY users often misapply products, leading to resistance in pest populations

When used improperly, some over-the-counter products can even pose health risks to children or pets. That’s why many homeowners opt for targeted professional treatments instead.


Final Thoughts: Be Proactive, Not Reactive

Identifying what pests you’re dealing with is only half the battle. Knowing what draws them in—and how to keep them out—is what makes the difference in long-term results. A combination of preventive steps, regular cleaning, and professional guidance is the most effective approach.

If pests have already made themselves at home, early intervention is your best defense. Whether you’re facing a minor nuisance or a major infestation, understanding the source of the issue will help you reclaim control of your space.
