Controlling Flea Beetles In The Vegetable Garden: How To Get Rid Of Flea Beetles
Fleas are small blood sucking insects which are found all over the world. They are not dangerous unless they bite humans or other animals. Most of them don’t cause any harm to humans but some species like the Asian Tiger Mosquito ( Aedes albopictus ) can transmit diseases such as dengue fever and yellow fever . These mosquitoes are very common in many parts of the world and they can even carry malaria.
The Asian tiger mosquito is one of the most destructive pests in tropical areas. It bites during the day when it’s active and then hides at night to avoid detection. If bitten, its bite causes severe itching and pain for up to three days afterwards. Thereafter, symptoms become progressively worse until death occurs within two weeks if untreated.
In addition to being a nuisance, these mosquitoes can also spread several diseases including malaria, encephalitis and yellow fever. In fact, there have been cases where the disease has caused death due to lack of proper medical treatment. Another reason why these mosquitoes are dangerous is because they breed in stagnant water sources and feed on animal blood. Water from human or animal waste is another source of breeding sites for the mosquito.
This means that they can breed in very dirty water and then spread diseases to humans and animals when they feed on them. It can also breed in very clean water and will still spread the diseases. These mosquitoes love to live around humans and their animal livestock where there is an abundant food source, so disposal of waste is a very important matter in mosquito control. Because they breed in dirty water, the best way to get rid of them is to get rid of the water where they breed.
When treating areas where mosquitoes can breed, remember that these pests can lay eggs in very small amounts of water. A bottle cap or a piece of wet paper is all that it takes for a mosquito to lay its eggs. Even treated water may not be safe since the eggs can survive in the bottom or even top layers of the water. For this reason, it is important to drain all water in containers or pools where mosquitoes can breed.
Some say that adding a little chlorine to the water used for treatment is enough to kill the eggs; however, it is still better to drain all standing water since this will be safer and more effective. For this purpose, it is best to use water that can easily be drained or will take longer to evaporate like a flooded field.
Traps are also a very important means of controlling mosquito populations. These traps attract male mosquitoes and prevent them from breeding so that there is no chance of these insects producing offspring. A good example of trapping is the use of ultra-violet lights at night time. These lights are designed in such a way that only male mosquitoes are attracted to them.
When the males get too close to these lights, they are trapped so that they cannot breed. There are also a few traps which can be bought over the counter but these are not very effective or only work for a short period of time.
Last but not least is the use of toxic chemicals as a means of controlling mosquito populations. These chemicals are applied in different ways like sprays and foggers. The chemicals can also be added to water sources where mosquitoes breed. These chemicals are very effective but they have the disadvantage of being harmful to humans and animals if used in large quantities or if the person is exposed to them for a long period of time.
It is best to only use these methods when there is an imminent threat of disease from mosquito-borne illnesses in an area.
Mosquito bites can be very irritating and itchy, especially if the victim has an allergic reaction to the mosquito saliva. A small lump will appear where the bite occurred which may itch for several days after the actual bite. For some people, this is the extent of their reaction while others may have more of an allergic response. For these people, the itching can be so severe that it interferes with sleeping or other daily activities.
The bite area may swell and even turn red. In some cases, a rash or hives may appear.
There are a number of home remedies which help to soothe the itching and reduce the swelling of bites. Before trying any of these, make sure to clean the bite area to reduce the chances of infection.
One method is to apply a paste made from fresh onions to the bite area. This helps to reduce the swelling as well as relieving some of the itchiness.
Another remedy is to crush an aspirin and mix it with water to create a paste. Apply this paste to the bite area to help reduce the swelling and itching.
It is also possible to get relief by making a paste using calamine lotion or a hemorrhoid cream and apply this to the bite area. These are commonly available over the counter at any pharmacy or grocery store.
If these methods do not provide relief, it is best to speak to a physician who can provide the correct treatment for bite related allergic reactions. They will be able to provide medication or other treatment which will help relieve the itching.
Once the itching and swelling has lessened, it is important to take steps to avoid getting bitten again. One of the best methods is to use insect repellent containing Deet on all exposed skin. While this is not a guarantee against getting bit it will definitely help. There are also different types of sprays which can be used inside the home to keep mosquitoes away; these are mainly used around windows and doors.
Some companies also make plug in devices which can be used to keep mosquitoes away from certain areas.
There are also many alternative methods for keeping mosquitoes away from the home or yard. One of these is planting Marigolds in and around the property. This is said to help keep mosquitoes away due to the scent given off by this flower. Garlic is another popular plant said to repel mosquitoes.
There is also talk about a herb called “Mugwort” being able to control or repel mosquitoes. There are also electronic devices on the market which are said to help keep mosquitoes away from certain areas.
Getting rid of mosquitoes is as easy as filling up a small plastic jar with water, adding in 2 tablespoons of yeast, and 1 tablespoon of sugar. Put the lid on the jar and shake it up. Now just go outside and hang the mosquito jar in a tree where you won’t see it, but the mosquitoes will. The next morning you’ll have fewer mosquitoes to deal with.
This mosquito trap should last you about a week.
The only thing that seems to work is plain old DEET, which not only keeps mosquitoes away, but also gnats, no-see-ums and other biting bugs.
