The two most common words to describe sand flea bites are painful and uncomfortable this is considered by many who have suffered fro these flea bites as an understatement. As the name might suggest the sand flea likes to live in sand, so the outdoors and beaches in particular are most likely places to find them, rather than in your home where the most likely cause of a flea infestation would be the cat flea.
The bites from a sand flea can be more dangerous than those of a cat flea, although if you have an allergic reaction to a cat flea bite or are infected by one of the many diseases they carry then these can be incredibly dangerous and you will need to seek medical treatment as a matter of urgency. So you must protect your self from sand fleas when you are out in areas such as the beach where they are likely to be.
Sand fleas are quite like mosquitoes in the approach they take to feeding on their pray, they bite and while biting they inject you with a chemical that slows the clotting process of the blood, this enables them to get the maximum blood for the least effort, however the chemical that you are injected with can cause an allergic reaction, and this can be quite dangerous, if you suffer from an allergic reaction to mosquito bites the chances are that you will suffer from an allergic reaction to the sand flea bites, you will need to take this into consideration when you go to the beach or other sandy areas and if you are at a higher risk you should have a plan prepared should you get bitten.
Sand fleas tend to gather in large numbers, like ants or mosquitoes, this means if you are unlucky enough to be in an area where they have gathered you will often suffer from multiple bites in a short period of time, and this can be very painful and extremely dangerous if you do have an allergic reaction as the amount of the chemical injected can be increased dramatically.
If you are going to the beach it is important to protect yourself from the effects of the sun but also the chances of getting bitten by sand fleas. Going at the hottest part of the day will reduce the chances of being bitten as the sand flea does not like hot dry conditions. The wearing of replants can also help as many are designed to reduce sand flea bites as well as other bugs.
It does not happen often but sometimes a sand flea when it has bitten will burrow beneath the skin on a host, they are tiny when they do this, around a millimeter in size and so extremely difficult to spot, however as they feed they grow, to around ten times the size, you will notice the lump below the skin.
If you do notice this type of thing and you have been bitten you will need to see a doctor and get the sand flea removed as doing it yourself will be difficult, painful and you will probably suffer from an infection so it is best a professional does it, this is one of the dangers of sand flea bites that you need to be aware of.
