Jejenes, sand fleas, no-seeums, misquitoes – cayo santa maria forum – tripadvisor how to get rid of canker sores in the mouth

I’ve been reading all the posts and links on these critters here on CSM forum and hope that you folks can clarify their differences. There are a lot of references that call these insects the same thing which appears to be confusing. Are Jejenes sand fleas ? Are no-seeums misquitoes ??

I travel in April / May and Oct. / Nov. and have been eaten alive my last couple of visits ( in contrast to posters who say that they don’t get bitten during this time) I do spend time at the beach during the day and have been bitten. I have walked around at dusk and early evening around the resort ( MCSM ) and been bitten. The thing is, I NEVER see any bug ? In my opinion they are all No-seeums !!!! At least in Canada you have a chance at swatting a misquitoe or black fly when your attacked. I use Muskol spray in the evenings, drop a anti-histimine and apply Hydrocortisone cream when I get any bite.


All of my bites ( by sand fleas at the beach ? or No-seeums at night walking around ? ) come up as a red welts the size of a loonie and are sore and very itchy for days. They then fester up into numerous small blisters on each individual bite. They last for a week and a half.

A sand flea is also known by many other names. For example, this crustacean (although it resembles an insect, the sand flea is actually not one) is also called a sand fly, beach flea, hop-a-long, no-see-um, biting midge, and punkie or punky. The sand flea is less than 1/8 of an inch (3 mm) long and is often difficult to see. It is a shrimp-like creature in appearance and ranges in color from pale to brownish. The body has seven segments and it has long legs that are used for swimming or jumping. They are known to jump to a height of at least 40 cm and therefore, it is unusual to experience a sand flea bite on upper body parts unless the victim was lying down. The bites are normally found in clusters around the ankles.

Sand fleas feed on organic and decaying plants. A favorite treat is seaweed on the beach. Whenever seaweed washes to shore, there will be a large number of sand fleas around and a sand flea bite is likely to occur. In general, the sand on the beach is a popular location for these fleas to live.

A sand flea bite is most likely to occur at dawn or in the evening and night time hours on the beach or other sandy areas that are near water. Wetlands, swamplands, creeks, and lakebeds are other areas where sand fleas can be found. Sand fleas generally stay close to their breeding ground. They never wander more than 350 feet or about 100 meters from their breeding area. Sand flea swarms produce a high-pitched wine. Therefore, if you are on the beach and you hear something like this, it is best to move or risk a sand flea bite.

The fleas will jump onto the feet, ankles, legs, and then bite. They are very persistent and quite annoying. Because of their small size, a sand flea bite occurs before individuals even know any sand fleas were in the area. Like a mosquito, a sand flea bites to suck blood. It is the female sand fly that bites. It does this in order to get the protein from the blood that is necessary for its egg laying. The sand flea bite involves the injection of saliva to thin the blood, making it easier for the flea to take blood from its victim. This same saliva triggers the body’s immune system to react.

Despite its size, the bite from a sand flea is quite painful. In fact, most of the time the bite is more painful than one from a typically larger mosquito. In addition to pain, the bite causes a large welt or rashes on the skin that can persist for several days. A fever may also occur. The welts or hives produced from bites are very itchy. Scratching the bitten areas should be avoided in order to prevent the development of an infection. Scratching will also prolong the symptoms of swelling, itch, and skin redness.

* Cutaneous: This is the most common form of Leishmaniasis and is characterized by numerous skin sores on the body that develop weeks or months after experiencing a sand flea bite. The sores usually leave scars that can be quite disfiguring.

Hey folks – well your going to get two types of bugs mainly down in Cuba. 1. Sand Fleas – they little guys are very hard to see but they mainly live in the sand and grass and come out at dawn to dusk. Do not walk on the grass at night and try not to walk on the sands either if you can. The other is the Mosquitoes which they spray for each night but they still seem to come out for their buffet dinner too. Best way to protect yourself from both is wearing closed toe shoes, high socks, long pants, and try not to wear perfumes as they seem to love that… You can tell the difference between the two bites as sand fleas are much smaller, less puffy, and red compared to mosquitoes which are larger bump like, less red, and more puffy in nature. One couple their little girl was laying on the grass at dinner time petting the stray cats/dogs and she ended up covered in sand flea bites – it was horrible as she was crying most of the next few days. If you have kids, bring some anti-itch lotion because it just may save your little ones and your own sanity !!
