The phone rings. “Help, I have found a baby hedgehog but I can’t pick it up to put it in a box because it is full of fleas. The fleas will get onto my dog and I have a baby and the baby will catch fleas.”
It’s a myth that all hedgehogs are covered in fleas. I’ve been running a hedgehog rescue for over 5 years and I have seen around 6 hedgehogs in that time that have had fleas. That is out of over 350 hedgehogs admitted. Yet, you’d be surprised how many people say that they cannot help rescue a hedgehog due to the risk of fleas.
The very few hedgehogs that have had fleas have either been incredibly poorly or have been young hoglets that were orphaned some time ago and have been struggling on their own.
In the very rare instance that a hedgehog has fleas, the fleas will not infest your dog, your cat, your house, your baby….. The hedgehog flea (scientific name: Archaeopsylla erinacei) is host specific. That means that it can only live on hedgehogs. It cannot live on anything else.
“But” I hear you say, “I’ve got a resident hedgehog who visits every night and I often see it scratching….” Well, itches can be caused by many things, just like they can in humans. It is nothing to worry about unless the hedgehog is found out in the day, which is a sign that is is unwell. If it is only seen at night, leave it alone.
What you are more likely to see on a hedgehog, are ticks. These blood-sucking critters also affect other animals and there are many species of them. Hedgehogs are affected by the hedgehog tick (scientific name: Ixodes Heagonus).
Increasingly mild winters mean that ticks are not being killed off and it is quite common and normal to see a hedgehog with a few ticks. One or two will not cause any harm and will drop off naturally once they’ve had their feast.
Sometimes a hedgehog is found that is absolutely covered in ticks. The ticks can cause anaemia and pass on other infections. Sometimes this is an indication that the hedgehog is sick, likely to be the case if the hedgehog is found out in the day. But lots of ticks don’t necessarily mean that the hedgehog is sick because milder winters mean that fewer ticks are being killed off. The unlucky hedgehog may just have slept in a tick nest and been targeted. But, the ticks will need to be removed to prevent anaemia.
The treatment of fleas and ticks is a specialist job and you can do more harm than good if you try to treat them yourselves. Flea treatments for cats and dogs will kill hedgehogs. If you remove ticks the wrong way, it can lead to infection and disease.
if you find a hedgehog that you suspect to be ill, follow the advice here and remember that a few ticks are absolutely normal and fine…..
