When identified, it’s important to get familiar with the behavior patterns of different pests so preventive and control measures can be applied appropriately.

    This guide will talk about the behavior patterns of different pests–including eating habits, reproductive cycles, behaviors related to environmental factors–and how this knowledge can help you better manage pest populations in your home or business environment:

    • Eating habits
    • Reproductive cycles
    • Behaviors related to environmental factors

    Common Household Pests

    Common household pests are different types of insects and rodents that can cause health risks and damage. Depending on where you live, fleas, bed bugs, cockroaches, ants, moths, and spiders may be common. Flies can also become a problem. Each pest has its own characteristics and behavior, making them hard to control.

    Different types of pesticides may be needed for the type of pest encountered. Sticky traps, baits, and other methods can help in pest control. Identifying the pest is important to determine the most effective treatment. Knowing the behavior patterns and eating habits of these pests can help eliminate them from a property.


    Ants are a common pest. They leave a trail of pheromones as they search for food. Working together, they build mounds and roads.

    To get rid of them, you need to know the species and their life stages:

    • Egg
    • Larva
    • Adult

    Also, their size differs depending on the species.

    Most ants eat sugars, proteins and fats. This is why they are attracted to kitchens. To remove them, use poison or insecticides. Plus, remove sources of food near your home.

    Bed Bugs

    Bed bugs are a troublesome pest. They are hard to spot and hard to remove. It’s important to get regular pest inspections to detect them.

    Bed bugs are small, about the size of an apple seed. They hide in tiny places like mattress seams or floorboard cracks. They feed on blood at night when we sleep. Bed bug bites cause itchy welts that can last days.

    Regular inspections can identify them before they become a problem. Treatments can then be put in place to quickly get rid of them, before they spread any further.


    Cockroaches are small, dark insects. They live in warm and moist places, like kitchens, bathrooms and basements. They can be different sizes and colors. Some have wings, some don’t. They eat glue and fabrics, ruining furniture.

    They also contaminate food with their droppings. To keep cockroaches away, limit access to food sources. Seal cracks around windowsills, door frames, and baseboards. Clean floors, counters, and sink drains regularly. That way, you can avoid a cockroach infestation.


    Fleas are minuscule, wingless bugs that suck blood from humans and animals. These pests multiply rapidly and bite often, causing serious discomfort. They typically originate outside, for instance from wild animals or stray pets.

    Recognize fleas by pet scratching, or red bites on skin from petting animals or being in an area with flea activity. Flea eggs are white to yellow, in small clusters on the floor or furniture. Also, flea droppings look like black pepper flakes when you press them between two fingers, or put them on a wet cloth.

    To fend off infestations,

    • groom pets regularly
    • vacuum inside

    If an infestation has already happened, call a pro exterminator to treat and remove any nests or colonies in the home.


    Flies are a common pest in homes and businesses. House flies, fruit flies, and drain flies are the usual culprits. These small, winged creatures can spread disease and contaminate food.

    To control their presence, it’s important to check your inside and outside for entry points. Seal them if necessary. Use fly traps or insecticides, which target the type of fly invading. To prevent them, keep a clean environment that is unappealing to flies. Eliminating food scraps and moisture may be enough to deter them.


    Mice can be a nuisance in crops – they eat the plants and contaminate them. Young mice eat up to the third order of leaves. Older mice like fruits, grains and seed heads. They tend to prefer juicy new growth over mature plants and feed at night.

    Mice have a special smell that can be sensed in places where they live or pass through. Droppings and gnawed marks on foliage, stems and trunks of fruit trees are signs of their presence. Additionally, they may dig tunnels in mulch or soil and often construct nests using grasses or other materials.

    Mice are among the most widespread pests in agriculture, making it difficult to control them. However, prevention is the best way to protect crops. Inspect your farm regularly for mouse activity and get rid of any food sources that might attract them. Traps can also be used to catch mice if signs of their presence are found:

    • Regularly inspect your farm for mouse activity.
    • Get rid of any food sources that might attract mice.
    • Use traps to catch mice if signs of their presence are found.


    Spiders can be scary creatures. But most are harmless and can help control other pests. Yet, some species, like black widow and brown recluse spiders, can be a nuisance. They can even be dangerous if they find their way into your home.

    So, make sure to research the spider species you want to use for pest control. Also, check if it’s legal to release that kind of spider in your area first.

    Pest Behavior

    Pest behavior is a phrase used to explain what bugs and mammals do that can be devastating to crops or plants. Over time, pests have adapted to get what they need to live and reproduce – food, shelter and water. It’s important to know which pests are frequent in a certain area and how to manage them.

    Usual pest habits involve:

    • Scouting an area to find food.
    • Breeding quickly.
    • Adapting quickly to changes in the environment.
    • Hiding during the day or resting close by to avoid predators.
    • Invading homes or other structures for warmth during cold seasons.
    • Moving around quickly when given the chance.

    Understanding these behaviors allows us to use better pest control methods, such as traps and baits, controlling access points, monitoring populations, vacuum cleaning, destroying nests, etc.


    Ants can be pesky pests. To get rid of them, you need to know their behavior and the best treatment options. Ants are social bugs that live in colonies with different castes, like foragers, soldiers, nurses, and workers. These colonies can be small or large.

    Ant nests can enter buildings through cracks and crevices around baseboards, windowsills, doorframes, or vents. To treat ants, set up bait stations or traps with material to attract them. Also, spray insecticides near entry points or trails. For severe cases of ant infestations, tenting and fumigation may be necessary to eliminate any nests inside buildings or hard-to-reach areas.

    Bed Bugs

    Bed Bugs are a nuisance. They are reddish-brown and 1/4 to 3/8 of an inch in length. These pests feed on blood and can survive up to 18 months without food. They tend to hide near bedrooms, in places like headboards, mattress seams, furniture creases, electrical outlets, curtains, and carpet edges. At night, they are active and will bite exposed skin that touches their hiding spots. Bed Bug bites may cause skin irritation and sometimes require medical attention.

    To pest-proof your home against these bugs, you should:

    • Vacuum regularly.
    • Use a steamer on furniture and carpets for eggs.
    • Wash bedding in hot water (130 ° F) for 10 min. per load.
    • Keep sleeping areas free of clutter.
    • Inspect second-hand furniture for infestation.
    • Avoid used mattresses or box springs.


    Cockroaches are common household pests. They like dark, moist places like kitchens, bathrooms, and basements. They eat food scraps, waste, pet food, and more. Cockroaches are nocturnal and can adapt quickly to their environment.

    They can be hard to spot, but they leave droppings which are usually black or brown. You may also smell a musty odor if they are in your home.

    It’s important to know their habits so you can stop them entering your home. Knowing where they hide, and what attracts them, can help you get rid of them. If an infestation is suspected, treat the area with an insecticidal spray or bait.


    Fleas are tiny bugs that live off mammal and bird blood. They are reddish-brown, without wings, and have long legs. Fleas breed fast. They love warm and moist places, like carpets and pet beds.

    Fleas go through four stages in their life: egg, larva, pupa, and adult. Each stage takes 1-2 weeks. Adult fleas lay eggs on their hosts or furniture.

    To fight fleas, it’s important to know how they act. Ways to control them include:

    • Grooming pets
    • Using insecticides on carpets


    Flies are a pesky sight in pest inspections. They come in different forms: houseflies, flesh flies, blowflies, and various fruit fly species. It’s key to recognize them by their features, behavior, and living areas.

    They feed on a variety of items, including animal waste, trash, and rotting organic matter. Also, they can spread diseases, like typhoid fever and dysentery, by contaminating food with their droppings.

    Typically, flies get in a building through wide-open windows and doorways. But, the most common way is through cracks in walls or roofing materials. To avoid fly infestations, seal off any potential entry points and dispose of or cover up food sources.


    Mice are a common pest in homes and businesses. They are small, grayish-brown rodents with long, slender bodies and large ears and tails. They have different behaviors and habits, making them tricky to identify and stop.

    Signs of mouse activity include:

    • Droppings
    • Tracks or footprints
    • Gnawed objects or walls
    • Evidence of nesting material like shredded paper or fabric near entry points or inside buildings.

    It’s important to know the habits of mice before a pest inspection. For example, they nest in dark places like crevices, attics, and tight spaces. They prefer foods high in fat and protein. So, keep food off counters, clear up after meals, and store food in airtight containers. Keeping your home clean will help keep mice out and avoid other pests.


    Spiders are arthropods. They have 8 legs and two body parts. These body parts have varied colors and textures. They range in size from tiny to large. Some can make webs up to 3 feet wide! Most spiders eat other insects, but some capture them in their webs.

    Spiders can be helpful by trapping pests. But they can also be a nuisance. Most bites come from spiders that feel threatened. To keep them away from home, it’s best to understand their behavior. That way, we can let them exist without fear of harm.

    • Don’t hesitate to call an exterminator if you suspect pests – better safe than sorry!


    Ants are a common pest, both indoors and outdoors. They often follow a leader’s pheromone trail to search for food and water. Varieties of ants include carpenter, odorous house, little black, and pavement.

    To stop ants from entering your home, seal gaps and cracks near windowsills and doorframes. Also, store food properly and use water and vinegar to wipe down counter surfaces. This removes any residue which may attract them.

    Bed Bugs

    Bed bugs are a parasitic insect that feeds on humans and warm-blooded animals’ blood. They are reddish-brown in color, and can range from a few millimeters to 1/4 inch long. They have flat, oval bodies, six legs, antennae but no wings. These pests prefer dark places and crevices, making them hard to spot.

    Signs of bed bug infestations are itchy welts or bites on your skin, dark spots on mattresses or sheets (bloodstains from crushed bugs) and a musty smell near hiding spots.

    To prevent an infestation, inspect for them in areas you suspect may be hiding places (including furniture cracks). Regular monitoring is also important as bed bugs are hard to detect until they reach later stages or reproduce quickly. When travelling, always check hotel beds for any signs of bed bugs before bringing luggage into the room. Finally, vacuum and use hot water to wash laundry often, as both help reduce the risk of a bed bug problem.


    Cockroaches are a common sight in homes and businesses. They’re active at night and scavenge for food. Eradicating them can be difficult, so prevention is key.

    Sanitation is essential for prevention. Sweep, mop, and vacuum to remove food sources. Keep storage containers sealed. Moreover, identify potential entry points around the house, and seal them with caulk or weather-stripping. This will provide extra protection against these unwelcome guests.


    Fleas are a common pest. They reproduce quickly and can live in any climate. They have even become resistant to many insecticides. To avoid an infestation, you need to know their features, habits, and where they hide.

    Fleas are small insects with long hind legs that let them jump far. They have an oval-shaped body covered in tiny hairs. Their color ranges from light brown to dark reddish-brown.

    To keep your home flea-free, regular cleaning is key. Change bedding often, vacuum carpets and furniture daily, mop floors weekly. Also, wash pet beddings with hot water frequently. Use insect repellents both inside and outside your home in areas where pets go. This will help keep pests away from your property.


    Flies can bring diseases and cause issues in your home. Different types of flies exist, like houseflies and fruit flies.

    • Houseflies eat garbage, pet food, and other organic material, both inside and outside.
    • Fruit flies feed on sugars from decaying fruit, wine, beer, and other organic material.

    To protect your home, you must identify potential sources of attraction or entry points. Seal cracks and small openings around doors, windows, and ventilation systems. Keep the areas around windows clean, to prevent flies from having an easy source of food or breeding ground.

    Make sure to practice good sanitation. Dispose waste materials properly to help minimize factors that attract lots of flies. Consider using fly traps with natural insecticides to reduce populations, when necessary.


    Mice can be a real nuisance! They can eat our food, bring disease, and cause other problems. To minimize their impact, we must understand their behavior.

    Mice are nocturnal and hide in dark, tight spaces like cracks and crevices. To reduce their population, seal all potential entry points into your home and store food in airtight containers.

    Also, use traps or bait stations near areas where mice have been seen. Check them regularly and discard dead pests properly. Regular cleaning helps reduce areas where mice nest and gain access to food.


    Spiders get a bad rap, but they’re actually beneficial to the environment. They eat other insects, meaning they can reduce indoor pests. Common spiders like house spiders, wolf spiders, and jumping spiders help regulate outdoor insect populations.

    Plus, they help pollinate flowers by trapping pollen on their bodies as they move from flower to flower. And their webs trap flying insects like gnats and mosquitoes, helping reduce their numbers in certain ecosystems.


    In summary, it’s critical to grasp the assorted forms of pests and their behavior. Knowing common pests, their stages of life, and habits enable pest control technicians to accurately identify and eradicate them quickly and safely.

    Being knowledgeable of pest behavior is vital for proficient and effective pest control, as well as a way of preventing future infestations.
