When to Use a Bug Bomb to Control Pests

Bug bombs—also known as total release foggers or insect foggers—use an aerosol propellant to fill an indoor space with chemical pesticides. These products are often marketed as all-purpose extermination tools that are easy for a homeowner to use. But is a bug bomb always the right choice when confronted with a home pest problem? Learn when to use a bug bomb—and when you shouldnt. Bug Bombs Work Best on Flying Insects Bug bombs are most effective on flying insects, such as flies or mosquitoes. They dont provide much control at all for cockroaches, ants, bed bugs, or other pests that most concern homeowners. So unless you live in the Amityville Horror house, you wont find a bug bomb to be of much help with your insect problem. Consumers are often fooled into using bug bombs for roaches and bed bugs because they believe the airborne pesticides will penetrate every crack and crevice where these insects hide. Quite the opposite is true, though. Once these hidden pests detect the chemical fog in the room, theyll retreat further into walls or other hideaways, where youll never be able to treat them effectively. Got Bed Bugs? Dont Bother With a Bug Bomb Are you battling bed bugs? Entomologists at The Ohio State University say not to bother using a bug bomb. Their 2012 study showed bug bomb products to be ineffective for treating bed bug infestations. The researchers studied three brands of insect foggers that list pyrethroids as their active ingredient. They used five different bedbug populations collected from Ohio homes as their variables and a laboratory-raised bed bug strain known as Harlan as their control. The Harlan bed bug population is known to be susceptible to pyrethroids. They conducted the experiment in a vacant office building on campus. The OSU entomologists found that the insect foggers had little adverse effect on the five bed bug populations collected from the field. In other words, the bug bombs were virtually useless on the bed bugs that are actually living in peoples homes. Just one strain of the field-collected bed bugs succumbed to the pyrethroid foggers, but that was only when those bed bugs were out in the open and directly exposed to the insecticide mist. The foggers did not kill bed bugs that were hiding, even when they were only protected by a thin layer of cloth. In fact, even the Harlan strain—bed bugs that are known to be susceptible to pyrethroids—survived when they could take shelter under a piece of cloth. The bottom line is this: If you have bed bugs, save your money for a professional exterminator, and dont waste your time using bug bombs. Using ineffective pesticides inappropriately only contributes to pesticide resistance, and it wont solve your problem. Bug Bombs Can Be Hazardous Regardless of the targeted pest, a bug bomb should really be a pesticide of last resort, anyway. First of all, the aerosol propellants used in bug bombs are highly flammable and pose a serious risk of fire or explosion if the product is used improperly. Second, do you really want to coat every surface in your home with toxic pesticides? When you use a bug bomb, a chemical cocktail rains down on your counters, furniture, floors, and walls, leaving behind an oily and toxic residue. If you still feel a bug bomb is your best option for pest control, be sure to read and follow all directions on the label. Remember that when it comes to pesticide use, the label is the law!  If the bug bomb treatment doesn’t work the first time, dont try it again—its not going to work. Consult your county extension office or a pest-control professional for help. Sources Jones, Susan C., and Joshua L.

Teen Pregnancy A Product Of Social Pathology - 856 Words

Teen pregnancy is known as a product of social pathology: parental neglect, emotional deprivation, insecurity, poverty, ignorance, violence. Pregnancy and motherhood in adolescence have a high pejorative, both for the same young to your child if the pregnancy goes to term. The difficulties are numerous, short and long term: the teenager is fragile and becomes more fragile even at pregnancy; medical, school, family and professional prognosis is sober, like the future of the child and the mother-child relationship; They followed pregnancies too early and are a high risk factor and the young mother is unlikely to reach a stable form one day, or even get to obtain a social status of family autonomy. In addition for reasons of biological or psychological immaturity of young teenager, these maternity seem so hard to take because our social system keeps contradictions regarding adolescents. The adolescent mother can conceive a child and give birth, but not prepared by education, social maturity and sufficient autonomy to raise it without difficulty.

My Philosophy of Education Summary Free Essays

In most of today’s classrooms we the students are seated in rows of desks. We are forced to sit and listen to the teacher, be it in biology, math, English, and memorize line after line of information. We are â€Å"receptacles† to be â€Å"filled† by the teachers. We will write a custom essay sample on My Philosophy of Education Summary or any similar topic only for you Order Now We have attained â€Å"knowledge† as an absolute if we complete the course with a %100. As society is seeing today, students being given the stamp of approval aren’t really ready to enter today’s world. If you’re going to school to be a biologist, it isn’t just enough to know that water enters and exits the cell through a process called osmosis. You need to know why! You need to be able to see all of this information on a much broader scope than it has been presented to you. Students need to be taught to absorb this knowledge rather than to memorize it. The main problem of today’s educational system is that it most of the times does not teach how to think critically. I propose a system of education in which teachers are not just depositing information in students, in which students are not just passive observers in an active world and in which knowledge is not just an absolute. The first thing that needs to be done to achieve my system (philosophy) of education is to change the way teachers are teaching all together. How many times do students talking amongst themselves outside the classroom about how good their teachers are. They go to class and interact with one teacher, and are taught everything from that one teacher’s perspective. In order to give the students a much broader perspective, two or maybe even three teachers, depending on the subject, should be placed in a class room. Each teacher would then present the information to the class. The students would then have a much broader spectrum of information to learn from. I am not implying that these teachers should tag-team forcing information down the student’s throat, but take different approaches in helping them absorb the information through problem posing. The teachers are not placed in this system to stand high up on their pedestals throwing assignments at the students, but are to b e working hand in hand with them. They would be learning from the students almost as much as they would be teaching them. In an educational environment such as this one, the students should be able to stand in the teachers place and teach the teachers and their fellow students as well. The students are active participants here. They should be learning as much from their peers as their teachers, if not more. This system could create a lot more â€Å"work† for the students, but not as much of the â€Å"busy work† we receive, and tire of, today. For example, students could be asked to do reflective writings, in which they would share what they have learned in the lessons. Student lead discussions would also take up a large portion of the time in these classroom environments. What better test of one’s knowledge than being put in a position where you are required to teach your fellow student? After each session both the student and the teach will go home feeling not stuffed with information, but a new view on some things that they would ponder as they head out into the rest of their dail y routines. The basis of this system isn’t what the teachers are teaching, or what the students are learning. It is how we perceive this thing we call knowledge. In this world knowledge isn’t something tangible. It is not viewed as an absolute. Knowledge is an ongoing process that will never have a climax or an end. It is something that will continue to grow and change through the timeline of our people. Knowledge is not what the students are learning, or what the teachers are teaching. It is the process of self-discovery. A teacher could tell a student that when you mix chemical A and chemical B they make chemical C. That isn’t the knowledge. The student can then actually mix chemical A and chemical B and watch them make chemical C. That isn’t knowledge. Knowledge is that individual’s learning of how those to things interact and why when they mix they form chemical C. Knowledge is the process of education through self-discovery. This system I have shown you would change the way education is viewed in this world. If we had teachers that actually â€Å"taught†, and students that questioned the answers they were given, we’d be much better off as a whole. If we keep going the way we’re going†¦ where are all the creative minds going to be coming from in the next few years? If students continue saying that A + B = C, what are we going to do when the world poses us more complex problems that require ingenuity, creativity and drive to solve? We just need to understand that knowledge is not just some gold star, or trophy each of us can achieve, but a method of learning and understanding that our society needs t How to cite My Philosophy of Education Summary, Essay examples
