Why are pesticides harmful?
They are designed to be, but only for the targeted pest. They are safe to use provided used responsibly. Pesticide poisoning is possible, but the people at greatest risk are those with repeat exposure (that work with it routinely)

Pest controls are people who are educated in bugs area. They get rid of any types of bugs or pest. This cost a lot of money because they use chemicals to get rid of all pests.
Advantage and disadvantage of traditional farming?
Advantages to traditional farming include there not being as much interference with the crops. This makes the crops healthier, because of fewer pesticides. Disadvantages to traditional farming include the fact that a lot more work is involved in everything from planting to harvesting.
What would happen if you light a hand warmer on fire?
it depends. If you just get the soil, it will work as an alternate gunpowder.(don't try it!)However, if you light the paper or whatever too, it will make a small detonator that just make smoke that could kill you.
How do pesticides work?
Depends on the type and some work in more than one way. For example boric acid is a stomach poison most bugs ingest when they groom, however, dusts can also clog the spiracles (holes in abdomen they breathe through) or dry out their exoskeletons (dessicants) Organophosphates act on their nervous systems and eventually they freeze (are unable to move) and starve. Contact sprays are simply absorbed through their bodies in most cases. Some insects eat the droppings of adults are are poisoned from adults who ate and passed poison bait, killing more than one generation.
Aims and objectives of pesticides?
The aim is to kill or control pests, with the objective being better conditions in which to live-work- or eat.
What do farmers use instead of pesticides when growing textile crops like cotton?
The first steps to protecting any crop from the pests which can damage or kill it should always include cultural controls. These are agronomic methods which can help reduce or control various kinds of pest species. Pesticides should always be the last resort when all other methods prove insufficient for economic control. US cotton farmers have found that cultural controls are rarely enough to prevent serious damage to the crop, so they are left with little choice but to use the pesticides. The only alternative is extremely expensive and frequently unavailable hand labor, which doesn't work on all kinds of pests.
What is the difference between biological control and pesticides?
Pesticides.Pests that affect human health and crops are a major problem.However, one possible consequence of using pesticides is that beneficialorganisms living in the same environment as the pests could also beharmed. This can happen because many pesticides kill more than justthe pest. For example, the lygus bug are pest that feedson alfalfa and canola plants and causes severe damage to these crops.However, pesticides that are sprayed to kill lygus bugs also kill bees.Another downside to using pesticides is that they can also harm thebeneficial insects that normally prey on the pests. This can result inthe populations of pests actually increasing because there are fewerorganisms to prey on them!Biological control.Another way to control insect pests is to use their natural enemies.This method, called biological control, can be very effective and limitsor eliminates the need for pesticides. For example, leafy spurge is aweed that was accidentally introduced into Canada in the late 1800s . Leafy spurge grows faster than naturally occurringpasture grasses. Cattle will not eat leafy spurge, so land that is infestedwith this weed cannot carry livestock. The black dot spurge beetle is asmall beetle that feeds on leafy spurge. The beetle was introduced into Alberta in 1983, and has been very successful incontrolling the spread of leafy spurge. Desirable plants, such as pastureand rangeland grasses, are returning to the areas where leafy spurgeused to grow. Although biological control can work very well, there can be risks.Whenever a new organism that is not native to the area is introducedto an ecosystem, there is always a risk that it will cause harm.
What do pesticides have that kills pests?
Most pesticides contain some form of chemical or organic compound in them that is toxic or detrimental to insects; sometimes there are a combination of compounds. This is referred to as the "active ingredient" of the pesticide.They are able to kill insects in a number of ways depending on the insect and the formulation.Some ways that pesticides work inlcude:Stomach poison (via ingestion)Fumigants (via inhalation)Neuro-toxins (via ingestion or inhalation)Metabolic disruption (via ingestion or inhalation) - here the product works by preventing some part of the natural life-cycle of the insect - e.g. preventing it from pupating, this is a slower action than other pesticides.
How does systemic circulation work?
systemic circulation - BETWEEN the heart and lungs
How do organophosphate pesticides work?
Organophosphate pesticides attack the nervous system of insects and animals leading to death. These are dangerous.
Humans can't adapt to toxic pesticides?
No. Insects do it by natural selection. The pesticides kill the less resistant and the more resistant go one to produce more resistant off-spring. This would only work for humans if several generations were exposed. Eventually we would get there but probably not in the time frame you are considering.
Are pesticides dangerous in treating bedbugs?
almost all pesticides are dangerous. You can use pesticides to kill them if washing your sheets doesn't work. Either way be sure and wash the sheets before putting them back on the bed. You don't want to sleep in pesticide residue.A2:One of the best ways to treat bed bugs is to use a combination of bed bug steamer, bed bug mattress encasement and diatomaceous earth. Some bed bug pesticides are non-residual in nature so they are not as dangerous as those that leaves a residue.
Ther are lady bugs coming in house appear to be headed towards devils ivy plant will they hurt plant?
on the contarary, lady bugs eat the pests on the plant and are even grown commercial for use in organic farming as biological pesticides. they pray or aphids mostly though the larva stage does most of the work
What are the pros and cons of using Pestacides?
Pesticides can be both beneficial and harmful. On the pro side, they help crop yield by eliminating pests that would eat the crops, such as the boll weevil, or various worms that attack corn, carrots, cabbage and other produce. This provides more food for the population. The con side is that pesticides often contain toxic chemicals that work their way into the food supplies and ground water. These chemicals can cause disease and death in humans.
Why are goats pests?
Goats are not pests!! They have whole lot of uses:meat, wool, dairy, and work! And by work I mean pulling carts and carrying packs. And the rumor about them smelling, only the males smell! You should definitely get one. :D:P
How do you kill ants and spiders?
You could simply step on them, or use some kind of pesticide. Look at your local home depot to find out what kind of pesticides they have. An exterminator would also work, but it would cost much more.
