In the heart of Texas, where the warmth and humidity foster a fertile environment for numerous pests, mosquitoes emerge as a common concern for many homeowners, especially in cities like Austin and Houston. 

As a pioneering pest control service in Houston, Natran believes in creating a safer and cleaner environment for everyone. Our endeavor is to protect homes and educate homeowners about the intricacies of pests, their habits, and effective control measures. Today, let's delve into the often-asked question: Why do we still suffer mosquito bites even after using personal sprays?

Understanding Mosquitoes and their Behaviour

Mosquitoes are more than irritating pests; they are sophisticated insects that have honed their survival skills over millennia. Their primary motivation for biting isn't malice but survival; female mosquitoes need the proteins from our blood to help develop their eggs. Armed with heat sensors, they can detect the warmth of a potential host, while their refined sense of smell leads them to sources of carbon dioxide – like the breath of humans. This makes them exceptionally skilled at locating their next meal.

Overview of Personal Mosquito Spray

Before understanding why sprays sometimes fail, it's vital to understand what these products are. Personal mosquito sprays are repellents to deter these insects from landing on or biting humans. They work by confusing the mosquito's sensory mechanisms or creating an invisible barrier that masks the signals we emit. Their effectiveness can vary based on ingredients, concentration, and environmental factors.

Understanding Personal Sprays

Types of Personal Sprays

Personal mosquito sprays come in a plethora of types and formulations:

  • Chemical Repellents: These are made with synthetic chemicals. DEET (N, N-Diethyl-meta-toluamide) is the most popular and widely recognized active ingredient.
  • Natural or Plant-Based Repellents: Derived from plants known to repel mosquitoes, examples include oil of lemon eucalyptus and citronella.
  • Picaridin-based Repellents: A synthetic repellent modeled after a natural compound found in the black pepper plant. It offers a comparable level of protection to DEET. Still, it doesn't carry its occasionally reported greasy feel or potential to damage plastics.

How Do Personal Sprays Work?

Irrespective of the base, personal sprays operate on a similar principle. They confuse or repel mosquitoes by masking the odors that attract them. When applied to the skin or clothing, they form a vapor barrier. This barrier is what the mosquitoes detect instead of the inviting warmth and carbon dioxide we emit. Chemical-based repellents like DEET function by actively repelling mosquitoes, while natural alternatives might rely more on masking our scent or making it unappealing to the insects.

Now that we've set the foundational knowledge, in the upcoming sections, we will explore why personal sprays sometimes fall short of their promise and the factors that enhance your risk of bites despite their use. We suggest choosing the right repellent for your needs and additional protective measures.

The Limitations of Personal Sprays

Personal mosquito repellents, while effective, need to be foolproof. Understanding their limitations is essential to use them more effectively and manage your expectations.

Incomplete Coverage

One of the most common reasons for bites, even after using repellents, is incomplete coverage:

  • Missed Spots: While spraying, it's easy to overlook certain areas, especially if you do it yourself. Mosquitoes are adept at finding these untreated spots.
  • Thin Application: Spritzing the repellent without ensuring an even layer can render it less effective. It's vital to ensure that all exposed skin has a uniform coating.
  • Over Clothing: While it's essential to treat clothing, especially if it's thin, spraying over clothes and not on exposed skin might leave you vulnerable.

Sweat and Water Resistance

The Texas sun can be scorching, leading to sweating, which can affect the effectiveness of your repellent:

  • Sweat Dilution: Heavy sweating can dilute the repellent on your skin, reducing its efficacy.
  • Water Activities: If you're swimming or involved in any water activity, the repellent can wash off, even if it's labeled as water-resistant. Constantly reapply after coming out of the water.
  • Humidity Factor: High humidity, common in areas like Houston, can increase perspiration and reduce the duration of the spray's effectiveness.

Spray Concentration and Reapplication

All sprays are not created equal. Their effectiveness depends on the concentration of the active ingredient:

  • DEET Concentration: Sprays with higher DEET concentration tend to last longer. However, after a certain percentage, there's no significant increase in protection.
  • Reapplication: Over time, the effectiveness of the repellent wanes. Depending on the brand and formulation, reapplication times vary. Always follow the manufacturer's instructions.

Factors Increasing Exposure to Mosquito Bites Despite Using Sprays

Mosquitoes are persistent, and certain factors can enhance your exposure, reducing the protection offered by personal sprays.

Proximity of Mosquito Infested Areas

Where you are making a difference:

  • Breeding Grounds: If you're near stagnant water sources like ponds or marshes, you're closer to mosquito breeding grounds. This increases the number of mosquitoes you're exposed to.
  • Lush Landscapes: Gardens with dense vegetation provide mosquitoes with resting places during the day's heat. You might encounter more mosquitoes if your outdoor activities are near such areas.

Time Spent Outdoors

The duration and time of day you spend outside play a role:

  • Active Hours: Mosquitoes are most active during dawn and dusk. You'll likely get bitten if your activities align with their peak hours.
  • Duration: The longer you stay outside, the more you're exposed, increasing the chance of bites, especially if your repellent begins to wear off.

Clothing Factor

Your choice of clothing can either deter or invite mosquitoes:

  • Dark vs. Light Clothing: Mosquitoes are more attracted to dark colors. Wearing light-colored clothing can reduce your attractiveness to them.
  • Coverage: While wearing shorts and sleeveless tops in the Texas heat might be tempting, full-sleeved shirts and pants provide a physical barrier against bites.

Importance of Mosquito Repellents and Sprays

Using repellents is not just about avoiding the itch or discomfort. The stakes are much higher when you factor in the potential diseases that mosquitoes can transmit.

Health Risks Associated with Mosquito Bites

Mosquitoes are vectors for various diseases, some of which can be life-threatening:

  • West Nile Virus: A significant concern in many parts of the US, including Texas. While most infected people show no symptoms, some might develop fever, headache, and other symptoms. Severe cases can lead to neurological diseases.
  • Zika Virus: This virus can cause congenital disabilities if pregnant women get infected. Symptoms are generally mild and include fever, rash, and joint pain.
  • Dengue: While rare in the continental US, cases have been reported. Dengue causes flu-like symptoms and can lead to severe complications in some patients.
  • Chikungunya: Another virus that can lead to fever and joint pain. It's found in many countries and has recently made its way to the US.
  • Malaria: Once prevalent in many parts of the US, it's now rare. However, travelers might bring it back from endemic regions.

Personal Comfort

Apart from health concerns, there are reasons related to comfort and peace of mind:

  • Itchy Bites: A single mosquito bite can lead to itching and discomfort that lasts for days.
  • Sleep Disruption: If you've ever tried to sleep in a room with even one mosquito, you know the challenge. The buzzing sound and the potential for bites can disrupt your sleep.
  • Outdoor Activities: Mosquitoes can ruin outdoor activities like picnics, barbecues, or just relaxing in your garden.

Additional Measures for Mosquito Protection

While personal sprays are a frontline defense, complementing them with additional measures can offer more comprehensive protection.

Use of Netting and Protective Clothing

Layering your defense is wise:

  • Bed Nets: Especially for nighttime protection, mosquito nets treated with insecticides offer dual protection.
  • Protective Clothing: Wear loose-fitting, long-sleeved shirts and pants. Some clothing lines are pre-treated with repellents for added protection.
  • Head Nets: A head net can be beneficial if you're in an area with a dense mosquito population.

Mosquito Control in the Environment

Your surroundings play a pivotal role:

  • Eliminate Stagnant Water: Mosquitoes breed in still water. Regularly check and empty containers, blocked gutters, and unused pools.
  • Use Larvicides: For large bodies of water that can't be emptied, like ornamental ponds, using larvicides can control the mosquito larvae.
  • Landscaping: Trim shrubs and tall grasses that provide resting places for adult mosquitoes.

The Role of Natural Repellents

Beyond commercial products, nature offers some alternatives:

  • Citronella Candles: Useful for outdoor activities, the scent of citronella can deter mosquitoes.
  • Lavender and Lemon Eucalyptus: Planting these around your garden or using their oils can offer some repellency.
  • Other Essential Oils: Oils like peppermint, tea tree, and geranium have some repellent properties.

Choosing the Right Personal Spray

While many mosquito repellents are available, picking the right one tailored to your needs ensures adequate protection. Let's dive into the factors that should guide your choice.

Considerations When Buying Personal Sprays

When selecting a repellent, consider the following:

  • Duration of Protection: Depending on your activity, you might need a repellent that offers extended protection. Always check the label to see how often reapplication is required.
  • Activity Level: If you're involved in high-energy activities or sports, you might sweat more, reducing a repellent's effectiveness. Opt for a water-resistant and sweat-resistant formula.
  • Age and Skin Sensitivity: Some repellents might not be suitable for young children or people with sensitive skin. It's always good to do a patch test before completing an application.
  • Environmental Considerations: If you're conscious about the environment, look for eco-friendly options that don't harm aquatic life or the ecosystem.

The Role of DEET

DEET has been a standard in mosquito repellents for decades:

  • Effectiveness: It remains one of the most effective repellents against many mosquitoes.
  • Safety: DEET, when used as directed, is considered safe for adults, pregnant women, and children older than two months.
  • Concerns: Some people are concerned about potential side effects, especially with high concentrations of DEET. Always follow label instructions, avoid over-application, and choose the proper attention.

Eco-Friendly Alternatives

For those seeking greener options:

  • Oil of Lemon Eucalyptus (OLE): Recognized by the Centers for Disease Control (CDC) as an effective natural repellent, OLE offers protection comparable to low concentrations of DEET.
  • Picaridin: A synthetic repellent inspired by the black pepper plant. It's as effective as DEET and is more friendly to plastics and fabrics.
  • Plant-Based Oils: While oils like citronella, peppermint, and tea tree have repellent properties, they often need frequent reapplication.


Mosquito protection, especially in regions like Texas, is not just about comfort; it's a health imperative. Understanding and employing the right strategies allows everyone to enjoy the outdoors with reduced risk.

Personal Responsibility in Mosquito Control

While services like Natran GREEN PEST CONTROL play a crucial role in controlling the mosquito population, personal responsibility is paramount:

  • Stay Informed: Be aware of your area's current mosquito activity and related health advisories.
  • Adopt Preventive Measures: From wearing the proper clothing to using repellents effectively, your actions can significantly reduce the risk of bites.
  • Household Control: Regularly inspect your property for potential breeding sites. Even a small amount of stagnant water in a discarded can can become a breeding ground.

Further Research and Developments in Mosquito Repellents

The quest for the perfect mosquito repellent is ongoing:

  • Nano-technology: Researchers are exploring nano-emulsions, tiny droplets that can slowly release repellents, ensuring extended protection.
  • Genetic Control: Some scientists are considering genetically modifying mosquitoes to reduce or eliminate their ability to transmit diseases.
  • Vaccines: While still in the experimental stage for diseases like malaria, vaccines can offer another layer of protection in the future.
