 How to Treat Bed Bug and Flea Bites

What to do when you are bitten by fleas

Do not rule out the possibility of having fleas in your home if you don’t own any pets. Some wildlife species that pass near your home or garden could also carry the pest. Fleas can jump from or fall off the animal and enter your home seeking hosts.

The most common flea species that attack both animals and humans are the Cat fleas or Dog fleas. These blood-sucking bugs are widespread in the UK and can quickly become a great nuisance as their numbers grow.

Here is what you can do if a flea bites you:

• Wash the bitten area with soap;
• Apply an ice pack or an antiseptic creme;
• If the bite marks discharge any pus, seek medical attention immediately.

Keep in mind that treating your bites does not solve the problem entirely. Contact your doctor as soon as possible, but ensure that your bite treatment goes hand in hand with a pest treatment.

What to do when you are bitten by bed bugs

However, inspecting your home and bed area thoroughly and finding what bugs have infested it is the only sure way to know what has bitten you. Below are some of the signs you should look out for near your bed.

 Differences Between Fleas and Bed Bugs

Bed bugs and fleas can look very similar, but there are a few key differences that set both apart. Let’s examine what these are below.

Both bites can cause allergic reactions, especially in children or people sensitive to allergies. When bugs bite you, they release saliva into your bloodstream. However, there are no records of bed bugs ever transmitting a disease to a human being. Fleas, however, are similar to ticks in that they can carry and transmit diseases from one host to another. If you conclude that you were bitten by fleas, contact your doctor immediately!

Comparison between fleas and bed bugs

Bed bugs do not fly or jump, but can only crawl. You will hardly ever see the insects while they’re biting you because this always happens while you are asleep. Should you spot a tiny bug crawling next to your bed, make sure to inspect it closely.

Fleas can jump approximately 30cm high. You can occasionally see them jumping on the surface of your furniture or away from your lying pet.

Fleas mainly feed on animal hosts but can bite humans as well.

Fleas live on pets or in areas where your pets like spending time the most (on bedding, a specific room corner, etc). They can also live in upholstery and carpets for a brief period of time.

 What Bit You − Bed Bugs or Fleas?

If fleas have infested your home, expect you, your family, and your pets to be bitten every single day. Flea bite marks usually appear immediately after the bite has occurred.

Bed bugs, on the other hand, will only bite you at night while you are sleeping and can feed on you for as long as ten minutes. After feeding for a couple of nights in a row, they will suddenly stop until its time to feed again.

It is important that you begin an exhaustive house treatment for these pests as soon as you receive your first bites. If you don’t do that, you’ll be stuck dealing with the symptoms over and over since their source will always lurk nearby. You should also consider the possibility of having dust mites.
