Went to get bikes out of the shed today and whilst I was unlocking the door, my ankles became covered in ravenous fleas, the ground outside the shed was "alive" with the tiny hopping friends.
I would like to get rid of the little hoppers, but would rather not use a nasty insecticide that would harm the rest of the wildlife of the garden- pond nearby. Any ideas other than use of a flame-thrower (can't risk burning shed down!!) ?
Some sort of bottle trap maybe ?, but theres likely to be thousands, and they breed very quickly.
Id stick to some sort of pesticide and just make sure you keep it within the bounds of the shed. You may have little choice.
Kill them with fire.

You can get flea specific sprays look in the pet aisle in the supermarket or pet stores
Sure they were fleas? Thought they only lived on animals/humans.

Fleas only need animals/humans to feed on, mostly animals. Indoors they tend to live and lay eggs in fabrics, carpets and stuff. They can live outdoors too.
You can get sticky flea traps, I assume there's no wildlife in the shed?

Only live ones. Quite possibly, their previous host has expired under said shed.
They won't last long without a host if you can avoid them in the meantime.
Yeah they can lie dormant for long periods of time, then when disturbed or they sense warmth from an animal they’ll leap to try and land on them.
Yeah we had a flea infestationt hat lasted 2 weeks without any animlas. The previous owners had dogs, fleas left eggs in carpets. Fleas all hatched in late summer and it was horrible.
You can buy sprays, poweder etc, or call local council who often have an exterminator.

They can stay dormant for months.
They can no doubt lay dormant for months during the cold winter months but in hot summer months their life cycles will be pretty quick.
Sheds get quite hot this time of year, I would expect them to die off pretty quickly without a host to feed on.
Water bowls with a drop of fairy liquid will help thin the numbers.
Anything soft and washable do so and keep it clear of the shed until things are sorted.
Contact a pestie to do a quick spray treatment is the most surefire way to clear.
Whereabouts are you?
Best spray is Indorex - can get it off Amazon - spray just the infected area. The buggers (eggs) can lay dormant for years. We had issues for ages with the odd flea (we have cas) and indorex was the best stuff - just dose any soft furnishings. Even having the cat's fully 'frontlined' didn't stop the odd one hatching until we zapped the places the cat's mainly sat.
bah
Thanks for ideas and advice. It is a strange one, as the shed (and house) are flea free. The fleas seem to be in the gravel and compacted rubble that makes up my hard-standing outdoor work area. I’ve never encountered fleas outside before and the sprays and potions all seem to be for indoor use. I really don’t want to poison the area with stuff that may harm the other nice creepy-crawlers.
Will contact professional flea killers tomorrow 🤓
If they’re just on the gravel then pour bowling water over it.
Boiling water is a genius idea.
The kettle is boiling….
Wellies donned….
