About This Product

Musca domestica, the common house fly, are a delicious enrichment food for your reptile, amphibian, or invert friend! The flight of house flies will keep your reptile or amphibian friend entertained and stimulated as well as provide a suitable food source.

House flies are about 8-12 millimeters in their adult form, making them a great size for a variety of reptiles, amphibians, fish, and birds. Josh's Frogs House Fly Pupae contains a healthy overcount, as not all pupae will hatch into flies. The pupae are packaged in a small deli cup with wheat bran.

How to Feed: House flies are fast! To make these flies easier to transport to your animal's enclosure, place them in the fridge for a few minutes. This will slow them down enough that they will not fly out when the container lid is open. Shake the house flies into your enclosure and watch your critter chase after their tasty treat! Any house flies leftover should be removed or else they may breed and lay eggs in your enclosure.

How to Store: When you receive your house flies, they will be in pupae form. The pupae should be stored in the fridge until you are ready to contain and feed off flies. Be cautious about leaving them in the fridge for too long—the longer house fly pupae are in the fridge, the lower the numbers of flies will hatch out. To hatch flies, simply place the pupae in a container with a paper towel or wheat bran substrate, kept between 77-86°F and 20-40% humidity.

No additional moisture is required to hatch the pupae, as the metamorphosis process in house flies is primarily temperature dependent, and any moisture on the pupae will result in deformed and/or decreased flies. If hatching at adequate temperatures, flies should emerge in 3-7 days.

It is possible to hatch pupae at a lower temperature but expect upwards of 3 weeks to hatch. The longer the storage time, the fewer flies will hatch out. Try to use all the pupae within a couple weeks.

Never Hatched...

The pupae were a little complicated to manage and never hatched, but I am sure it was a rookie mistake on my end.

Worth every penny!

I always get my orderS from Josh's Frogs alive and fresh and my idolomantis love their flies!


Perfect size, great hatch rate

I ordered these hoping they would be the appropriate size for my juvenile regal jumping spider. I wasn't disappointed. The hatch rate is amazing and my spider goes bananas for them. I put a little honey water in a bottle cap with some paper towel to keep the ones I'm hatching for the week alive and haven't had any issues. Tip: pop the flies (not pupae) in the freezer for 2 minutes and it's basically an off switch. I toss em into the spider enclosure and they spring back to life within a minute.


Consistent product

Glad I found these guys and only 70 miles away. If you follow the instruction everything is fantastic. I will continue to order! Outstanding customer service
