Moth balls and rats: the truth - A box of      mothballs won’t stop rats. Mothballs are a clever mixture of pesticides      and deodorants compressed into t a tiny, vaporous, white ball. They will      effectively keep moths and moth larvae at bay, but mothballs will do      nothing against larger, nuisance animals. The vapors off mothballs are      toxic but they cause more issues for the humans in the household than they      do for the rodents you’re trying to get rid of. Rats are difficult to get      rid of once they’ve declared an area desirable. Instinctually, a rat will      not leave its territory unless the need is dire. Venturing beyond the      established scent markings and safe pathways may mean exposure to      predation. Mothballs are not a strong enough deterrent to force a rat out      of its comfort zone. When trying to get rid of rats, you need to make sure      any clean-up around your home or business has been taken care of and that      areas allowing the rats access inside are sealed off. These little rodents      can chew, so metal is the most advisable patch for external holes. Instead      of putting down mothballs, consider placing some baited, snap traps in the      areas of frequent rodent travel. 
             Do mothballs or ammonia help repel rats?
             Do mothballs or ammonia help repel rats?      Rat problem is surely complicated and disturbing for all members of the      family. It is hard to find anyone who will think that rats are cute      otherwise majority hates their presence because of the obvious reasons.      They will damage the walls of your house, make a lot of disturbance and      worst of all rats are responsible for spreading a number of diseases so it      is better to get rid of them as soon as possible. You must be thinking      about finding easy and simple solutions for dealing with the rat problems,      but the hard part is that getting rid of them is not that much easy. Rat      repellents are commonly found in the market and sellers usually associated      big claims with them. However, we strongly suggest that you should stay      alert towards the fact that majority of repellents are not that much      affective and thus it will be unwise to associate high level of utility      value with them. The best way of getting rid of rats is to trap them and      relocate them to distant and safe places and after removing them you      should seal all the holes and entry points. In simply words for getting      rid of rats you will have to stop their access towards your property. Rat      repellents are extensively found and among different types of products      that are available ammonia and mothballs are the most popular ones, but      the big question is that do mothballs or ammonia help repel rats? Let’s      try to find the answer in this section.             
Mothballs      These are actually small balls which have been made using pesticides and      deodorant. These are also used for storing clothes and other items from      the damage, which can be inflicted by mold or larvae of moth. Different      uses are associated with mothballs, but important point to highlight here      is that people also regard them useful for repelling rats. In reality      mothballs are not considered as affective for driving away rats in fact      they bring many harms and damages because of the fact that pets and      children can find them and if they consume them then there are many      adverse affects to face. In simple words, these are not useful for getting      rid of rats in any case so it is better that you should not depend upon      them.             
Ammonia      Ammonia it surely has a bad smell which even humans can’t bear. Actual      concept present behind its use is that bad smell will force the rats to go      away, but this is a weak concept. Only because of bad smell rats are not      going to leave their homes for dying outside by the hands of predators.      Therefore, it is better that you should avoid using these products because      they will not provide any decent result to you.             
 
             There are some really bizarre things thrown around on the internet when      you research how to get rid of rats. Mothballs and ammonia are two things      that we often hear homeowners using in a big to ‘repel’ or ‘deter’ these      animals, but generally, most of the time, we are told they do not work.      That’s why we are called in - to do the job that these so-called      repellents just don’t do.       
      Mothballs, for example, are designed to repel moths. They contain a      mixture of ingredients, one of which is insect repellent, and a rat isn’t      an insect … That’s probably why it doesn’t work.       
      We can come up with three reasons why mothballs aren’t a good idea when it      comes to trying to get rid of rats. In fact, we can probably come up with      a hundred, but we’ll start with three:       
1 - They are designed to get rid of moths, not rats.       
2 - They are actually quite dangerous to the environment.            
3 - They contain known carcinogens, and these cause      cancer.       
      If that wasn't bad enough, you might actually poison your poor household      pets by using mothballs, because, as we said, they’re dangerous to the      environment. You certainly wouldn’t want Patch the dog or Jess the cat to      come into contact with them. If you're a household with pets, neither      ammonia or mothballs are a great idea. They are quite the opposite.       
      The mothballs that you can buy from stores in the US contain      paradichlorobenzene and naphthalene. Both of these ingredients are      volatile, and slowly transform into a gas from a solid - the form of      mothballs. Just short term exposure to either of the two ingredients can      cause adverse effects in humans - irritation to the eyes, nose and lungs,      even causing coughing, and it could also lead to nausea and vomiting, and      also headaches and an upset stomach. If you are exposed to these two      compounds for a long period of time, more serious effects can start to      happen, and this can include permanent damage to the kidney and liver.       
      Ammonia really is no better either, often bringing pretty negative side      effects, yet homeowners are still using it as a way to somehow repel or      deter rats. Even short term exposure to this gas, both colourless and an      irritant, can cause a number of problems, including irritation to the      eyes, nose and throat, a cough, tightness to the chest, a scratchy throat,      and more. Long term exposure to the poison can be very dangerous, and even      fatal in some cases, and that’s what you’ll want to avoid having the      hanging around your home. If it could damage you and cause serious harm to      your health, imagine what it could do to a much smaller human - a child,      or even a pet.      
      These ‘homemade remedies’ might be cheaper and easier than the more      traditional ways of getting rid of rats, mice and other rodents, but they      certainly aren’t good for you or the environment. Trapping is the best way      to deal with this problem - lethal snap traps that deal with the problem      immediately, and without causing any undue stress or harm to the animal.      We would love to recommend live cage traps, but unfortunately these often      prove ineffective also. Relocated rats very rare survive anyway.
