    So How Do Roaches Get Inside Your House In The First Place?

    This is a common question among those who have newly discovered an infestation in their home. Most of the time, there’s a stigma attached to roaches: these insects only gather in filthy, unsanitary places where they can feed off of exposed food.

    While this is certainly the case in areas that are unkept and not properly maintained, it doesn’t mean that this is the ONLY way to attract roaches.

    More often than not, these pests just want a warm place to find food, and they end up sneaking in through minute cracks in the structure of a home. Roaches are able to flatten their bodies almost instantly in order to squeeze through a crevice, which means that even the smallest of openings can be a door for a cockroach. Unfortunately, not much can be done to prevent these pesky insects from entering a house or apartment, because it’s nearly impossible to search your home for any possible hole that could let roaches inside.

    Furthermore, once you’ve become host to a few roaches, it can be difficult to tell that they’re actually in your home. Roaches love the dark, and thrive in small cracks of home surfaces like inside walls, baseboards, and under furniture. Oftentimes, the only evidence of a roach is the unsettling twitch of antennae protruding from a small space. This is dangerous, however, because roaches leave a trail of potentially toxic secretion wherever they go. This means, essentially, that if you have roaches, they’re streaking a possible poison through your home.


    How Does Roach Spray Actually Work?

    Roaches are an unfortunate fact of life:

    After having survived many millennia without extinction, they’re often cited as some of the planet’s most resilient organisms. When faced with this fact, many people think they don’t stand a chance against this versatile type of bug. And yet, there’s a simple solution sitting right on the shelf of a local store: Roach spray.

    Undoubtedly, you’ve heard that sprays can do the trick to get rid of these household pests.

    But, you may be thinking, when roaches have outlasted other animals for thousands of years, how can a simple spray kill them in a home?

    Did You Know

    Roaches breathe through millions of microscopic pores in their exoskeletons, which create a perfect delivery system for poison.

    Roach spray uses a chemical agent that effectively stops the nervous system of the roach, either at first contact or via a slow-release weakening of the roach’s body. When you’ve got the proper spray and you’re using it correctly, you can cleanse your home of these unpleasant creatures.


    Why Should I Even Use Spray For Cockroaches?

    With so many different types of products to kill off roaches, it can be dizzying to know what to choose for a roach-free home.

    From cockroach-killing gels to roach bombs and even poisonous roach baits, the choice isn’t always clear to the average consumer, especially when strapped with the stress of knowing that you’ve got these insects crawling through your house or apartment.

    The primary reason that most people select roach spray over any other method of extermination is that it’s not toxic to humans. Secondly, roach spray can be found in nearly every grocery store, and is readily available from online retailers like Amazon.

    Most importantly, you don’t need to be a professional exterminator to be able to spray your home and kill off your roach problem. Most sprays are designed solely for at-home use, giving you the power to clear out the roaches yourself, with no exterminators involved.


    Are There Any Homemade DIY Spray Options Available?

    In a time where the notion of self-service is the way to go, it’s not recommended to take a “DIY Get Rid of Roaches” route. Despite the growing trend of all-natural, chemical-free cleaners and household agents, these types of homemade roach killers can end up doing more harm than good in your home by attracting EVEN MORE roaches.

    For example:

    If you search “how to get rid of roaches in apartment naturally” online, you’ll find a multitude of different homemade roach killers… Whether you’re using citrus extracts, spiced oils, or cucumber peels, you’ll achieve the same result: the roaches will crawl over these obstacles and scuttle away, leaving their trail of secretion behind them.

    This will only lure in more roaches, which compounds your problem. When you clean up the homemade cockroach killer, you’re exposing yourself to the secretions, which are rampant with biological toxins. It’s a lose-lose-lose situation.


    The Important Question, Are Sprays Safe For My Children & Pets?

    So, how can a chemical that’s deadly to roaches be safe for humans? Will my pets be safe in a home that’s been sprayed to kill insects? Do I need to evacuate my home in order to fully rid it of these unwanted pests?

    These common questions are completely natural. However, roach spray truly is the safest and most effective option for eliminating these insects in the home. How can that be?

    Well, the main reason lies in the sheer size of humans and pets. Of course, if ingested in a large quantity, roach spray would be harmful to larger animals and humans.

    However, roaches are small, and need only a small dosage of spray in order to die.

    Today’s Homeowner Tips

    The amount of the chemical agent that is present in roach spray would have to be multiplied thousands of times over to replicate the results in a body as small as a cat or a baby.

    Also, the holes in the roach’s exoskeleton deliver the poison faster than by way of ingestion, which in turn creates the fatal effect. In humans or pets, the journey from the mouth to the body would weaken the chemical agent to a point of uselessness. As long as you store the roach spray in a safe place away from pets and small kids, there’s no way that the amount of spray will reach toxic levels.


    What If The Spray Doesn’t Work?

    If you’ve been dealing with roaches for a while to no avail, it’s easy to think that these critters have already won the battle in your home. However, don’t give up hope! Sometimes, a little patience is key in keeping up the fight against household roaches.

    Many roach sprays will offer a kill-on-contact guarantee, but some species of roaches have evolved to repel this kind of poison. The underlying effectiveness of most roach sprays is to create a slow-release, long-lasting toxin that not only kills existing roaches, but creates a toxic barrier against new roaches from inhabiting your home.

    If a roach has laid eggs, these eggs will be resistant to roach spray. Because of this, it can feel as though a spray isn’t working when really, the original adult roaches are long gone and the roaches crawling around are from eggs that have hatched. Be persistent, be patient, and keep on spraying.
