General Mantis Care – Praying Mantis for a pet!

Praying Mantids have long been kept as pets, with some hobbyists having one or two, and some building up collections into the thousands of insects. It’s very easy to replicate the natural habitat of a Praying Mantis in the home, and with a few pieces of inexpensive equipment, you can put together a professional looking setup that generate great interest and even aesthetically pleasing additions to the home.

There is much to be learned about these amazing invertebrates!  Basic care of Mantids is fairly easy, but once you are done reading this highly generalised care sheet, you will want to check out the advanced care sheets and see if there are any special requirements for the species that you own/are interested in owning.

Caring for your Praying Mantis:

Keeping a Praying Mantis as a pet is fun and relatively speaking, is not hard at all. But of course a Praying Mantis does need proper care to stay healthy and strong. It doesn’t really matter if you have bought your own pet Mantis, or if you found a Mantis in nature, most of them need the same basic care. The following points will help you in keeping your Praying Mantis happy and healthy!

Habitat/enclosure for your Mantis to live in:

So the general rule is that the height of the habitat/enclosure is 3x the length of the Mantis, and 2x its width. So let’s say your Mantis is around 3-4cm in length, then an enclosure with dimensions of 12-15cm high x 6-10cm wide x 6-10cm deep is perfect, or, for example; anything around half a pint to a pint in size, including  24-32oz Deli pots, or a cricket tub which is also great at this stage too (figure 1).

Figure 1. Cricket tub enclosure is a simple and adequate enclosure for a small/medium sized Mantis.

You don’t want anything too big as the Mantis won’t see the prey you put in there, and might starve.

If the Mantis is not yet an adult, you need to make sure there is something for the Mantis to hang from in order to moult too. So either a mesh lid, or mesh at the top just under the lid, and/or horizontal twigs/sticks. These sticks/twigs  need to be high enough for the moult to occur without the Mantis touching the bottom (hence the 3x body length rule).



For adult Mantids such as this one in figure 1 (Adult female Otomantis scutigera), the rule of 3x height no longer applies because the Mantis is an adult and as such has no more moults.

With regards to foliage etc…well, it’s up to you. People who have one or two Mantids tend to make their enclosures as aesthetically pleasing as possible. This is purely for our own benefit of course, the Mantis couldn’t care less how pretty it is ha ha….. I suggest the odd piece of foliage as this might make the Mantis feel a bit more ‘at home’, not too much as to make the place look too busy though, and also, if there is too much, then prey will just hide, and your Mantis won’t see it, again, possibly leading to your poor Mantis going hungry.


Different species have varying requirements, environmental living conditions is just one of them and is reflected by their natural habitat. Some species live in damp forest areas, while others live in desserts or dry grasslands. Certain ‘beginner’ species like ones from the Hierodula genus (Giant Asian Mantids for example) or the Sphodromantis genus (Giant African Mantids etc) can tolerate a relatively wide temperature range (22-30C during the day, with a dip down to 19-21C in the evening). This means that providing the room you choose to keep them in is within this temperature range, then no external heat source is required.

However, if you decide to keep a more ‘exotic’ species then you must research into the care of these Mantids from a variety of sources. If no care sheets are available, then research into the origins of the Mantids can be done so that an understanding of the natural habitat of that species can be achieved, and thus, recapitulated in captivity.

If the room you decide to keep the Mantis in does not provide adequate heat then external heat sources will need to be used such as; heat mats, heat lamps or both. Please go here for an introduction into how to regulate the temperature of your Mantis enclosure.


Place substrate on the bottom of the enclosure. This substrate can be anything that will absorb water and that will not mould easily. For example: tissue paper, vermiculite, potting earth, shredded wood, pieces of bark or sand. The purpose of the substrate is to release water slowly, thus keeping the humidity in the tank a bit more constant (see more specific care sheets for information regarding humidity requirements of your species of Mantis).

To ensure adequate humidity, you need to spray the substrate at the bottom of the enclosure every day, or every few days during the week. Depending on the type of housing and on the species of Mantis you keep, you will have to regulate the humidity levels accordingly. For example, if you have more ventilation holes in your enclosure and your Mantis requires 60-80% humidity, then you will need to spray water more often to keep the humidity levels up.

To understand more about humidity and how you can adjust it to suite the requirements of your Mantis, please go here.

Feeding your Mantis:

The food requirements of a Praying Mantis will vary depending on a number of factors, such as; development stage of the Mantis, sex, species, general health, size of prey and size of the Mantis. Also, adult males require much less food than females.

For example, a young nymph will only be eating small fruit flies such as Drosophila melanogaster or Drosophila hydei. Or, if they are a particularly small species, then even smaller prey such as springtails may have to be considered. Young nymphs of certain larger species such as Idolomantis diabolica however, can take green bottle flies or house flies immediately after hatching from the ooth. These young nymphs are likely to require feeding every 2-3 days due to the fact that smaller prey have a lower nutritional content than larger prey items, also, young nymphs tend to be much more active and as such, require more energy.

Older nymphs however, maybe 3rd-6th instar can be fed slightly larger prey (green/blue bottle flies, small hoppers and small roaches etc…), they are also much less active, this means that they can be fed fewer times a week, maybe every 3 -4 days. Larger and more mature Mantids such as sub adults or adults can be fed even larger prey and may only require feeding every 5-7days.

A general rule is that until the Mantis reaches at least 5th-6th instar stages of development,  the size of the prey given is not to be more than half the size of the Mantis itself. Older adults of pre/sub and adults can tackle prey 3/4 its own size, with larger species being capable of taking prey their own size.

All this is dependent upon your objectives though, things such as how fast you want your Mantis to develop and whether you want to fatten your adult female before breeding and/or for ootheca production by gravid females will dictate how often you feed your Mantis, and also, the size of the prey you give them.

When feeding your mantis, make sure the mantis will actually eat the food you offer it. When you introduce live food to the enclosure of the mantis, this food can hide or escape. When this happens often the mantis will starve. To make sure your mantis will eat what you offer it, you can watch until he has caught the food. You can also offer the food with tweezers directly to the mantis. If you do this carefully the mantis will grab the live food item directly from the tweezers and will start eating instantly. Prey that moves a lot, like flies, will generally be caught much more easily then prey that hides, like roaches or crickets.

As is the case with yourself, I can’t emphasise enough the importance of a varied diet for your Mantids. Only feeding them one type of food item is not the most ideal situation to maintain a Mantids health. If you can, a diet made up of a variety of flies (blue/green bottles), hoppers (young locusts), adult locusts for larger Mantis species, roaches, meal worms, morio worms, wax moths and other prey items available is ideal. However, I appreciate this is not always possible, so if you can only feed your Mantis one or two prey items, then it is important to gut load them with the appropriate food items in order to maximise the nutritional value of the prey. Examples of gut loading includes; a mixture of honey, water and bee pollen for flies, whilst for roaches, worms and locusts, fresh fruit and vegetables are perfect.

Remove uneaten food and clean the enclosure:

Mantises aren’t the tidiest of diners, and they’ll leave behind all manner of debris including legs, wings, chewy or hard bits they didn’t like such as stomach contents  etc., and you need to remove these regularly to prevent mould/bacterial growth that will infect and/or kill your Mantis. Also, it won’t smell or look very nice.

When cleaning the enclosure of your Mantis, just remove all the substrate and wash the inside of the enclosure with hot water. Do not use any detergent as this can harm the Mantis. Dry the enclosure and add fresh substrate and any cleaned foliage you may have taken out.

  1. Very informative great, I have ordered some dead leaf mantids from yourself when I receive them will they be able to handle small-medium crickets?

    • Hi, thanks for the order 🙂

      They would be able to handle them yes. But to be honest, i feed them on large fruit flies until they are 3rd instar, then i feed them green bottle flies. So i have no idea if they will want to eat the crickets or not.

      I hope they do, good luck.


  2. Hi I shall be ordering my first mantis soon what do you suggest as a good beginner genus and what would be ideal food. I have a large 5ltr sweet jar enclosure so could say a Giant African or Asia be ok I shall be ordering from yourself

    • Hi Darren, welcome to the awesome mantis hobby 😀 You’ll have a wall full in no time!

      So yes, you already identified 2 of the genus that i always recommend for beginners.

      Hierodula membranacea, Sphodromantis lineola, Rhombodera basalis, and Phyllocrania paradoxa are all good starter species. And i have them all in stock 🙂

      They are all currently eating large fruit flies (Drosophila hydei), so you’re good to go…’s just a question of deciding which you like the look of.


  3. Hi Mitch. I currently have 1 mantis but want more. Am worried about heating as I live in Uk. Please can I ask what wattage heat mat to get for one mantis as the heat mat I had before (6 watt) didn’t seem strong enough to keep temperature. Also if i wanted to keep several mantises would the wattage have to increase. Thanks in advance☺

    • Hi,

      It just depends on what the temperature is in the room that you plan to keep them in (day and overnight)?77

      I usually recommend a matt between 7-11W, so if it’s very cold in that room, then an 11W might be better.

      If you plan to keep a few different vivariums on the mat, then ypu’d just need to get a larger matt…the wattage will increase depending on what size you get.

      Hope that helps,


  4. Hi I’m just wondering how much food a 6th insta giant Asian mantis would need? I would like to get one but I’m unsure of what the instars mean and can’t find much info about it

    • Hi,

      I’m currently out of those now, sorry about that. I’ll be getting some younger ones next week sometime…..and they’ll be eating large fruit flies 🙂


    • Hi Erin,

      It really depends on the type of enclosure you have? And also, what type of substrate you’re using?

      Just want to keep an eye on left over body parts of prey items, and try to pick those out as often, and quickly as possible, as that leads to mould and fungal growth etc….

      You can keep a self-sustaining enclosure with soil substrate and clean up crew (springtails and dwarf white woodlice) for a very long time without having to clean it hardly ever (except for maybe taking out the decor once in a while to wash, and wiping the inside of the enclosure walls etc…).

      Hope that helps 🙂


  5. Hi Lee, glad to hear all is going well mate 🙂

    Thanks for your continued support, much appreciated!


  6. Hello, really interested in the ‘cat mantis’ but I’m new to this hobby. Would it be a good beginner.
    Many thanks

    • Hi, I wouldn’t recommend the Heterochaeta orientalis (Cat Mantis) for a forst mantis.

      They’re quite tricky to raise, especially when so young.


  7. Hello my daughter is keen on a mantis this website is fab for info, which type would you recommended for a first and low maintenance mantis please?

    • Hi,

      I can highly recommend the Hierodula membranacea (Giant Asian Mantis, Sphodromantis lineola (Giant African Mantis), or Phyllocrania paradoxa (Ghost Mantis) 🙂

      They are all great beginners, and don’t take too much looking after in terms of extra heat, or care etc….

      All available on the website, so it just depends which you prefer the look of.


  8. I really want a spiny flower mantis, just need to know what things I need to get like what size habitat should I get them ? And if there is a starter kit for that mantis

    • Hi,

      The starter kits i sell are perfect for most of the mantis species i sell, including the Spiny Flower 🙂

      You may want to upgrade to a larger vivarium when your mantis gets larger, but a Spiny Flower is fine in the starter kit for most of its life.

      You wouldn’t need to get anything bigger for it, for a good few months.

      Hope that helps 🙂


  9. Hi Mitch
    I have a live terrarium which isn’t over crowded more like a mini landscape,

    It’s housed in a bio orb fish tank,

    Would this be suitable housing for a Mantis ??

    Thank you

    • Hi Holly,

      I’d have to see the set up to make a proper assessment. However, if it’s the typical type of Bio Orb tanks that i think you’re referring to, then i don’t find those types of tanks particularly suitable for mantids.


  10. Hi there!
    I’ve just order my first Mantis (Oxyopsis Peruviana) from you and I’m insanely excited for the arrival of the new addition.
    The site is very informative which has come in super handy! Thank you 🙂

  11. Hi Mitch just came across your site. I’m intt in the giant Asian mantis as my first and being 4th insta what size Viv would you recommend. I was looking at the exotera ones & would I need a heat lamp or Matt.

    • Hi Simon,

      THe 4th instar Giant Asian is just about still ok for a moult or two (2-4 weeks) in the basic starter kit I sell (32oz Deli container & accessories etc).

      But then you’ll need to think about upgrading to something around 20x20x20cm (or something around that size). The Exo Terras are ok, but the main issue is your mantis seeing its prey in there.

      So you could put it straight in one, but you need to make sure it sees, and catches prey ok. If you’re not sure, you could always take it out and put it in a smaller container just for feeding times.

      External heat requirements depends on the temperature of the room you’ll be keeping it. You should be aiming for around 24-28C daytime, and a drop to 19-21C overnight is good for them.

      Hope that helps 🙂


  12. Hi there
    I have just received our ghost 3instar praying mantis, and everything is great arrived safe ,he is small what do u suggest we feed him. We have had large mantis before so this is new. Thanks

  13. Hi there!

    I’m completely new to mantis keeping, and I’m wondering if Indian Flowers would be alright for a beginner? If not, I’m considering a giant asian and I’m curious what food would be good to feed either when I recieve them from you.

    • Hi Lucy, welcome to your new passion 😀

      So yes the Indian Flower (C. elongata) is perfectly fine for a beginner 🙂 As is the Giant Asian (H. membranacea), so whichever you choose is fine.

      It just depends what kind of look and size you fancy for your first. The Giant Asian is huge in comparison to the Indian Flower, and also the Giant Asian is better for interacting with (handling etc), as they are more docile than the Indian Flower, which can be a little more skittish, but settles down once it gets used to you better.

      Hope that helps 🙂


  14. I’m interesting in purchasing an African Flower mantis from you. I currently already have a spiny flower mantis, so how would the care differ from that? I notice there isn’t a lot of care information online for them since they’re such a new kept species.

    • Hi Luke, they’re both African Flower species, so they can be kept pretty much the same mate.

      Actually the G. amoena are a little more hardy than the P. wahlbergii, so they can tolerate a wider scope of conditions.


  15. Brilliant site 👏👍. My son has a few mantis and I’ve just ordered another from this site. Very well informed from the care sheet.

  16. Hi I have a 3 week old thistle mantis from you and he’s lovely.
    I’m just concerned as I’ve had him for 3 weeks and feed him a fruit fly everyday.
    He has made no signs of molting yet apart from constantly hanging upside down.
    Is there anything I can do to help. He’s still eating regularly but stopped moving so much,

    • Hi Evie,

      How many fruit flies are you feeding him daily? If it’s just one, then that’s way too few.

      What stage is he? I’m guessing around 4th instar, so you need to be feeding him at least 6-10 fruit flies every 3-4 days, or if you want to feed him every 1-2 days, then you should give him 3-4 flies at least.

      Also, what temperatures are you keeping him at?
