My Recommendation On How To Use This Article

Choosing from all of these ways can get confusing so here are my recommendations.

  • Lets say if you’re using insecticides as the main choice then you can just spray insecticide and pesticides whenever you feel there is too much infestation. The effects of insecticides and pesticides remains for many days. So, till then you don’t need to do anything else. Do, remember insecticides and pesticides are  chemically made and can be harmful to humans so use it carefully..
  • If you’re thinking to use natural ways to get rid of bugs then you can use neem oil, essential oils, lemon spray to keep bugs away. It can be hardwork but it’s good for your plants and is also good for you. You need to look for infested plants individually and then spray these natural made pesticides so, that’s why it can be time consuming.
  • If you’re having slugs problem then use beer. Beer is a lot less time consuming since you can target the areas where there is more infestation and just keep the beer and you don’t have to work yourself to keep slugs away. Beer will attract slugs and will kill them.

Some Additional Information That You Should Know

During heavy infestation it is always better to spray all of your plants with strong insecticides as it is the fastest way to kill dangerous bugs but it also kills good bugs and during pollination time it is better to avoid using insecticides and pesticides as it will kill the helpful bugs that is very necessary for your plants survival and also for the ecosystem. You can use other ways mentioned in this article during pollination times that will keep bugs away. They are all very effective.

Fertilizers And It’s Effects

Along with these solutions you need to also use proper fertilizers and  water to keep your plants healthy. Without these two elements it will be difficult for your plant to survive no matter what you do. You need to check the soil occasionally to know whether there is sufficient fertilizer or not. Sometimes due to fertilizer problem you’ll see increase in bug infestation. If that happens then you should immediately change the fertilizer all together. Don’t check by spraying insecticides or pesticides as it can solve the problem temporarily but the infestation will again increase once effect of insecticides and pesticide are gone. So, without thinking put your efforts in changing the fertilizer if that happens before it’s too late. You’ll see your plants turning yellow, losing it’s green glow and leaves may start falling if that happens then check the fertilizer and if you find some problem in it immediately change it.

Climate Change Effects

Due to climate change infestation can also increase if you feel like the infestation is not decreasing then use the above mentioned ways to get proper result. These bugs often disappears after that particular season is over but during the season they can cause sufficient harm to your plants so you need to make sure your plants are properly taken care of.

Dangerous Effects Of Flying Bugs And How To Get Rid Of Them

There are also flying bugs that can also totally destroy your plants and it’s a little difficult to get rid of flying bugs attack. So, the best way to get rid of them is to note the time when the attack is high and then use any one or mixture of the solutions to get rid of them. You can also personally go and spray insecticides and pesticides over their group of those flying insects to get rid of them. This is often often done by many people and it’s very effective. You can use natural ways that are also effective. If you can’t spray the natural solution directly over flying bugs then just spray the solutions over the plants and whenever those bugs comes in contact with the plants they will perish.

The conclusion is both chemical and natural ways are very effective you choose what you want to use and how comfortable you are using it then use it accordingly.
