Chemicals previously known to block mosquitoes’ carbon dioxide receptor can’t be used around people because of unpleasant odors and health safety concerns. To identify more suitable compounds, the team developed a computer simulation method to screen almost half a million chemical compounds in search of structures that might interact with the receptor. They identified 138 compounds that were pleasant smelling, inexpensive, and considered safe for human use. Does mosquito have 47 teeth? Instead of teeth, they have a 6-pronged Micro-needle system, which allows them to pierce the skin and find blood vessels. Two of their outermost needles have 47 tiny “teeth,” which they use to saw through skin Penetration time corresponds to the insertion of the stylets into the host skin and usually lasts <10 sec.

When shown an array of colors from the visible spectrum, the mosquitoes also responded strongly to red, orange and cyan. They showed no interest in the colors violet, blue, green, and green-yellow. What four colors attract mosquitoes? The study found that when exposed to carbon dioxide, a gas humans constantly produce via exhalation, yellow fever mosquitoes (Aedes aegypti) developed heightened sensitivity to particular colors like red, orange, black, & cyan . Exposure to a chemical that shut down the mosquitoes’ carbon dioxide receptor rendered them unable to react to carbon dioxide from exhaled breath. The scientists tested the response of these mosquitoes to skin odorants by placing them in a wind tunnel with a plate of glass beads that had been worn in socks for several hours to give them the scent of human foot odor. Both Aedes aegypti and Anopheles gambiae mosquitoes — which transmit dengue and malaria respectively — were much less attracted to the scented beads after being exposed to the chemical. These results showed that the receptor responsible for detecting carbon dioxide also detects skin odorants.
Colors like red, orange, black, & cyan attract mosquitoes.
Mosquitoes use to detect both carbon dioxide and skin odor, and they identified compounds that interact with the receptor. The findings may help guide strategies to control mosquitoes and the diseases they transmit. Mosquitoes have an amazing ability to zero in on us from afar and head straight for our bare skin. Unfortunately, mosquitoes are much more than an itchy annoyance. They transmit several serious diseases including malaria, one of the most common infectious diseases in the world. Nearly 1 million people die of malaria every year. Mosquitoes also transmit Dengue viruses and filarial worms. Female mosquitoes have nerve cells called cpA neurons that have a receptor to detect carbon dioxide. This enables them to sense the plumes of air we exhale. But mosquitoes are still attracted to human skin even in the absence of carbon dioxide

The most effective treatment for cockroach allergies is prevention by removing the cause. Taking measures to keep cockroaches out of your home is essential for allergy relief. Tips for doing this include: *keeping a clean and tidy home *getting rid of dirty or dusty piles of clothes, dishes, papers, or other belongings *cleaning counters, stoves, and tables of food and crumbs regularly *sealing up damp areas or leaks where cockroaches can access water *keeping food containers tightly sealed in the fridge *tightly sealing all garbage cans *sweeping floors regularly to remove food crumbs and dust *using traps, exterminators, or other measures to kill or repel cockroaches. *If you see or suspect cockroaches in your home and you’re experiencing allergy or asthma symptoms first go to doctor. Then call us for Cockroach Treatment. Among the many cockroach species, it is the American cockroach Periplaneta americana and the Periplanetaaustralasiae which are the most likely to bite humans. German cockroaches have also been known to bite humans. It may be dangerous if not treated.

A cockroach allergy is also known to trigger, exacerbate, or even cause asthma in adults and children. It may affect children worse than adults, especially in urban areas where cockroaches are more common in larger numbers. Allergies to cockroaches may be one of the top causes of asthma in children in inner cities. Cockroach allergies have also been shown to increase typical asthma symptoms in children more than in those with asthma not caused by cockroach-related exposure. Asthma symptoms in both children and adults may include - whistling or wheezing while breathing, difficulty breathing, chest tightness, discomfort, or pain, difficulty sleeping due to the above symptoms.

Salmonellosis, Typhoid Fever, Cholera, Dysentery, Leprosy, Plague, Campylobacteriosis, Listeriosis. Symptoms of cockroach allergies are similar to those of other common allergies. They’re most similar to symptoms of dust, mites, or seasonal allergies. People with cockroach allergies may notice their symptoms last beyond the time seasonal allergies would naturally lessen. They may also occur when dust or mites aren’t present. Common symptoms of cockroach allergy include – coughing, sneezing, wheezing, nasal congestion, nasal or sinus infections, ear infections, skin rash, itchy skin, nose, throat, or eyes, runny nose or postnasal drip etc.
Data: Based on the research study
About one week after mating, the female produces an ootheca. On average, females produce one ootheca each month for ten months, laying an average of around 14-16 eggs per case. The pregnant cockroach will carry an egg case for a few days before placing it in a safe location. Female cockroach can produce 9-10 ootheca and each ootheca can give rise to 14-16 eggs. Collaterial glands are present in female cockroach as part of reproductive system. These glands are branched tubular glands opening independently on the dorsal side of the genital chamber.
On an average, females produce one ootheca each month for ten months, laying an average of around 14-16 eggs per case.
Your food is main attraction of both German & American cockroaches. So put your foods & vegetables in safe places where cockroaches can’t reach. We use Herbal base Pesticides for removing Cockroaches in your Residents and organizations. Mainly removing cockroaches & eggs from hidden places and entry points will drive cockroaches away and prevent future infestations. Inside the home, seal cracks in dark places like cupboards or building cracks with caulk, repair water leaks, and remove moisture in crawl spaces and other dark areas by increasing ventilation. Time to time cockroach treatment is required. Because cockroach eggs can’t be seen in hidden places. After hatching they come out and increase their populations. For this reason we treat 3 to 5 times between 15 days gap. Sometimes we use nontoxic chemical and special type of Gel for removing Cockroaches. Cockroaches are scavengers, so they will crawl around until they find what they need. Smell is a sense cockroaches rely heavily on. While scavenging, their antennae will move from side to side to smell the food in the air. Once they have identified what they want to eat, they will use their mouth to consume it.
Dr. Bhattacharyay use Herbal & non-toxic system to control Cockroaches.
Cockroach infestation in Indian homes and other places is a significant problem. They’re not the best companions but we often find ourselves stuck with Indian cockroaches. India is the world’s second most vastly populated country after China. It’s understood that this land will then not only be populated by humans. We have plenty of animals and annoying insects, pests like cockroaches and reptile species in this country.
Cockroach infestation is a significant problem.
Bedbugs don’t have wings, so they rely on animals or humans to carry them from one place to another. They typically get into your home after an overnight trip — by hitching a ride in your luggage or clothing. Or they can enter your home if you bring in secondhand furniture that’s infested. They can also travel from one apartment to the next if a building or hotel has an infestation. Although bedbug bites are rarely dangerous, they can be very itchy. In some cases, they become infected or cause an allergic reaction. What attracts bed bugs? Reality: Bed bugs are not attracted to dirt and grime; they are attracted to warmth, blood and carbon dioxide. However, clutter offers more hiding spots. What is the biggest cause for bed bugs? They can come from other infested areas or from used furniture. They can hitch a ride in luggage, purses, backpacks, or other items placed on soft or upholstered surfaces. They can travel between rooms in multi-unit buildings, such as apartment complexes and hotels. Bed bugs are not a sign of a dirty home or poor personal hygiene. Bed bugs are not known to spread disease, but can be an annoyance because their presence may cause itching and loss of sleep. If you think you may have bed bugs, it's very important to do a thorough inspection by a non toxic Pest Control Organization and to begin treatment as soon as possible.
