Bioactive Stuff No One Told You About
There are some things about bioactive enclosures that just aren’t talked about. Some things are seen as negatives and no one wants to say anything bad about bioactive, and others people just assume everyone knows. I get many of the same questions over and over again, so I’d like to put some less-discussed aspects of bioactive together in one post.
   1.) Let your enclosure “cycle” and plants grow in before adding your animal.
   When you first set up your enclosure, plant it, and add your clean up crew, you should seal it up (more or less depending on how humid the parameters will be), and let it grow in for at least a month before you add your animal.
For high humidity enclosures, you can cover any mesh or vents loosely with plastic wrap. Low humidity and arid enclosures should be left more open.
There are multiple reasons for this.
First, it allows the plants to establish, recover from any transplant stress, and grow roots. This means they will be far less likely to die from the first time they’re stomped by your pet. 
Second, it allows the clean up crew to establish a strong population, to be able to handle the waste output of your pet, and be less likely to be eaten to extinction.
Third, it allows micro CUC, other organisms of the decay cycle -- bacteria and fungus -- to establish, to break down the waste further, after your macro CUC have dealt with it.
Finally, it allows the environment to balance out, and go through its first mold bloom, so you are less likely to deal with it once your pet is in the enclosure. You’ll likely have some mold again after the pet moves in, but it will be less extreme.
There are times you will not be able to seal up the enclosure and wait for it to establish before your pet moves in. Although not ideal, it’s quite possible. You may lose more plants, and have more cleaning to do for the first few months.
   2.) You will probably need to remove most of your pet’s feces for a month or two after they move in.
  It may take time for the CUC and the other organisms in the substrate to populate enough to deal with your pet’s waste, depending on how deep your substrate is, substrate surface area, how many CUC bugs you started out with, and the size of your pet (and your pet’s waste). 
Keep an eye on poop. If you see it one day and it’s still there twenty four hours later, that means you need to be picking it out, and it’s too much for your CUC to deal with. Just picking it out with a tissue and tossing it is plenty; you don’t need to scoop out any substrate with it. Keep doing this until poo disappears within a day.
   3.) You will still have cleaning chores.
 Although people often switch to bioactive because it involves fewer substrate changes, there are still clean up chores to do. 
CUC will only be effective for waste on the substrate layer. 
Most will not climb, and even those that do (my orange Porcellio isopods think they’re semi-arboreal) will not do so in numbers significant enough to deal with poop and food smears on perches, hides, and enclosure walls. 
In addition, they will not eat urates. Urates break down quickly, but it is best to lightly mix them into the soil. In some cases, urates from certain species can burn your plants if they’re not broken up.
Cleaning and maintenance chores for bioactive enclosures can include lightly stirring urates into the substrate, washing poop and food off walls, perches, and decor, adding fresh biodegradable material like leaf litter, and watering, trimming, and other plant care. Sometimes CUC will need to be augmented or thinned, and in some cases fed or otherwise cared for.
   4.) Bacteria are everywhere.
   You will see people adamant about two schools of thought when it comes to bioactive:
People warning you to never, ever sterilize your leaf litter and substrate before using it, because that will defeat the purpose of bioactive.
or
People warning you to sterilize everything before it goes into your enclosure, because of the potential for parasites, disease and pests.
To be honest, neither is more correct than the other! And partly it depends on what species you’re keeping in your enclosure, and where you’re getting your materials.
The reasoning behind the first school of thought is that in order to be a healthy bioactive enclosure, the substrate needs a thriving population of bacteria and fungus. This is true. However, bacteria and fungal spores are everywhere in the environment. Even if you sterilize your substrate and your leaf litter, bacteria and fungus will colonize your substrate as waste is added.
This is the same concept behind fishless cycling. In fishless cycling, a tank is set up, and ammonia is added as a food source for bacteria. Bacteria from the environment will colonize the filter media. Although you can buy bacterial kick-starters to add to your tank, they aren’t necessary. Bacteria that break down animal waste are everywhere, and will “find” the tank.
In your bioactive enclosure, decaying organic material will provide a food source for microorganisms like fungus and bacteria. Even if you start out with soil you’ve baked, bacteria and fungus will colonize the soil. It may take longer to get started, which might mean a few weeks longer of removing feces by hand, but it will reliably happen, no problem.
Sterilizing your soil, leaf litter, and plants may be a good idea if your tank inhabitants are delicate and susceptible to environmental parasites and diseases, such as some amphibians. 
Keep in mind that even if you are boiling or baking your substrate, leaves, and other materials, there are some infectious organisms that are not destroyed by the heat, and it will not affect contaminants like pesticides and fungicides.
  5.) You will get mold.
  One of the things that tends to make keepers panic is when mold shows up in their bioactive enclosure, often in massive quantities. Mold is normal!
Fungus and mold are a natural and important part of the decay cycle, in nature, and in your enclosure. The macro clean up crew (isopods, springtails, insects, annelids) will break down feces, leftover food, and other waste, and bacteria and fungus in the substrate will break it down further.
When the enclosure is first set up, even without your pet, there will be an excess of decaying matter, along with fluctuations in humidity and other parameters, which will cause a mold bloom. Within a month, a properly set up bioactive enclosure will balance out, and there will be less visible mold.
This doesn’t mean there’s no fungus in your enclosure! Healthy bioactive substrate will be full of spores and fungal mycelium, thread-like vegetative structures of the fungus. The mycelium break down waste as part of the decay cycle, and also form a fascinating symbiosis with the plants in your enclosure, helping them to bring up nutrients through their roots.  
This is one reason that it is a bad idea to do heavy stirring in your substrate, as you will disturb and break up the mycelium. If you must do excavations, try to do only a small section of the enclosure at a time, then allow the mycelium to re-establish.
White mold will not harm your inhabitants. Other colors of mold happen as well, such as green and yellow. You may also have mushrooms pop up from time to time! While mycelium is the vegetative part of the fungus, mushrooms are the fleeting fruiting bodies. These are also natural and harmless (and beautiful), and may end up as a quick snack for your CUC.
The only time to worry is if you get black mold. Black mold spores can be dangerous for you and your pets to breathe. If you must clean up black mold, be sure to wear a properly rated particulate filter mask.
   6.) You will get detritivore gnats and detritivore mites.
  When we set up bioactive enclosures, we’re creating the perfect environment for countless animals. When we design the enclosures, we want them to be hospitable to our CUC, which eat decaying organic matter like feces and mold.
Isopods, springtails, and lesser mealworms are not the only detritivores interested in eating poo and fungus, though, and many other detritivores are ubiquitous in the environment and much more mobile than the CUC we choose for our enclosures. 
When our enclosure attract these less desirable “volunteer CUC” we call them pests.
I would warn anyone who is thinking about doing bioactive that if you can’t handle fungus gnats in your house, you really shouldn’t do bioactive.
Gnats and mites both tend to freak out new bioactive enclosure keepers. However, they’re just doing the same job as our assigned CUC, and we can’t blame them for finding our perfectly maintained environments ideal for their needs. 
The gnats most typically attracted to bioactive enclosures include fungus gnats and phorid flies. 
The fungus gnats are attracted to the fungus growing in the enclosure’s soil (a necessary part of the decay cycle, remember), while the phorid flies feed on dead insects and CUC. 
Fungus gnats are particularly annoying creatures, as they seem to enjoy flying into people’s noses. They also end up in a lot of mugs of tea.
The methods for eliminating fungus gnats from houseplants are not an option for bioactive enclosures. The things that would poison fungus gnats would also poison the CUC, drying the enclosure out entirely would kill the CUC and make the enclosure uninhabitable for your pet, and top dressings would be dangerous to the CUC and animal inhabitant. Besides that, because bioactive substrates are inherently perfect for them, the fungus gnats would just come back.
To keep fungus flies to a minimum, I suggest yellow sticky traps around the enclosures. Fungus flies are attracted to the color yellow. Make sure no pets -- including mammals, birds, or others -- have access to the traps! In bioactive enclosures for non-climbing insects, it may be useful to place these traps on the inside of the lid.  
Unlike fruit flies, apple cider vinegar traps are not particularly effective for fungus gnats.
Phorid flies are more likely to be cyclical, and more common in bioactive enclosures with larger insects. When a roach or large beetle dies, they will swoop in and start doing their work on the body. Phorid flies can be kept to a minimum by either having a robust clean up crew that takes care of insect bodies quickly (such as lesser mealworms in a bioactive roach colony), removing all dead insects promptly, or by setting a trap to remove the phorid flies when they show up.
Detritivore (or soil) mites can scare a new bioactive keeper because of their resemblance to parasitic mites which can infest our pet reptiles. However, detritivore mites are harmless to our pets, and eat decaying organic matter and fungus in our enclosures. Mites are everywhere, and occupy all sorts of positions in the ecosystem. Detritivore mites are inevitable in bioactive enclosures, but you may never see them! They are extremely small.
As a general rule, don’t worry about soil mites in your bioactive enclosures; you can’t eliminate them anyway. 
However, it’s a good idea to try to keep them out of CUC cultures. This is because in the worst case scenario mites can overwhelm springtail and isopod cultures, and may at least slow down their reproductive rate. To prevent mites in CUC cultures, placing the enclosures in trays of diatomaceous earth and keeping cultures separated are good husbandry practices.
I hope this helps anyone thinking of going bioactive, or new bioactive keepers. If anyone has anything to add to this, please do!

If your shitty neighbors let their cats run loose
Why not trap the cat? Free cat. Or take it to a shelter. Or remove a pest as you see fit if you care about the environment or it’s bothering your plants/animals/feeders. Outside cats shouldn’t be a thing, and it’s the best thing for you, the cat, and the environment to fix that.

The installation: INTRUDE by Amanda Parer Detroit, MI In Australia rabbits are destructive pests. The work represents a larger-than-life presence. It was spectacular for me - but probably not for the reason of the artist's intent. Enjoy! http://parerstudio.com/intrude-public-light-art-installation

Something is rapidly killing young apple trees in North American orchards. Scientists are stumped
Weather-related stress—drought and severe cold—could be an underlying cause, researchers reported this month in PLOS ONE. Early freezes are becoming more common across the eastern United States, for example. But that doesn't appear to be the whole story, and scientists are examining an array of other factors, including pests, pathogens, and the growing use of high-density orchards. "There are a number of things going on that are going to be really difficult to sort out," says David Rosenberger, a retired plant pathologist who worked at Cornell University.

Important reminder about seed collecting and storing
While I was on holiday in Lanzarote back in November I collected a good number of seeds from species I had identified with certainty, but there were also a few mystery ones. One day my boyfriend and I were walking along the beach and I snatched a long dry seedpod from a shrub and put it in my backpack. There and then I could only tell the plant was clearly a woody member of the Fabaceae due to the bipinnate compound leaves and obvious dehiscent pods, but since there are so many similar species, I couldn’t really tell which, or even if it was one I already knew. 
Once I got back home in Scotland I stored all my seeds neatly, quarantined the mystery Fabacea ones, and put one in a sealed bag with moist paper to test if and how quickly it would germinate. In the top photo you can see the resulting seedling, which I’m really happy with as I thought the test might not go well and I’d have to try again later on in spring, but that wasn’t the last of the surprises. I hadn’t looked at the rest of the seeds since I had stored them away, and when I did I was so relieved I had taken in consideration the possibility they might be carrying pests, as Fabaceae often do! Three of them were hosting Bruchid beetles from the family Chrysomelidae, which decided to emerge after almost four months in storage. I’ve spent a considerable amount of time trying to pinpoint exactly the species, but I have been unable to -although I suspect the genus to be Bruchidius- so if any of you dear entomologists recognise them, please let me know! They are ~5 mm in length and I hope the gif is good enough to show the characteristic mottled coloration. 
If you are storing seeds which may carry beetles and their larvae, make sure you do so in thick plastic or glass, as many species can just chew through a good number of softer plastics and materials (mealworms, the Tenebrio molitor larvae, will happily chew through tinfoil for example, that’s something I learnt incidentally while keeping a hedgehog). Luckily I had anticipated the possibility and stored them properly (hence why I used the word “quarantine”), so none escaped and all three have been disposed of. Now I just need to know what species my Fabacea seedling is!

Deadly imports: In one U.S. forest, 25% of tree loss caused by foreign pests and disease
Scientists have documented at least 450 foreign insects and pathogens that have found their way to North America and feed on trees. Most do little damage, but more than a dozen have proved extraordinarily destructive, wiping out tree species—or even whole genera—as functioning members of forest ecosystems.

The cat Kill Trap story frightens me because I live in New Zealand and there's a anti-cat movement going on here at the moment because a cats eat birds, and NZ holds it's birds as precious. People on Reddit have confessed to buying Kill Traps, or even just going out to shoot them. The movement is rather tiny at the moment, but it's still there. I think one town has even made a law that if you have cats, you cannot replace them once they die. Just, I hate this country right now.
I do not advocate for having an animal suffer unjustly, but I’m not going to lie to you.
I am very against letting cats roam. In doing so they spread disease and have massive impacts on the wildlife because they are invasive. Whenever I saw I cat in my yard before I had rabbits and chickens, I’d let my dog loose on them.
He wouldn’t hurt them, he wasn’t vicious, he just liked to chase things. Once they stopped running he lost interest, but it give the cat a good fright and keep them from shitting in my garden.
Once I got chickens and rabbit they were a much larger threat, and you can’t exactly tell strays from the ferals. My mother and I would use live traps, and we had a rule. First time we saw them, we’d shake the cage around and give them a good fright, then send them on their way. Second time, we’d take them to the shelter. If there was a third time, we would put them down ourselves. We warned the entire neighborhood. This also applied to small dogs, and an altered rule for possums and raccoons. Larger dogs we would shoot in the hind end with a pellet gun, as they were usually a much more immediate threat.

Hi okay I'm really embarrassed about this. I have a SERIOUS fruit fly problem!!! How can I get rid of them?!?!? I try to keep on top of dishes but I work two jobs and get an average of 5 hours of sleep a day (I work mostly nights) and have absolutely no energy and I dont have a vacuum yet so I cant suck them up. Please help this is really embarassing and it's really bringing me down...
Yes! Nothing to be embarrassed about, it’s really common.
In the past, I’ve used the cone method. What you do is you take a tall glass or cup and put a bit of apple cider vinegar, red wine vinegar, or wine in the bottom. You can put a few drops of soap too. Then, roll a piece of thick paper or cardstock into a cone with a tiny hole at the bottom, and tape it up so there’s no gaps in the sides. Then, tape the cone to the top of the glass, like a funnel. Tape the sides so there’s no openings between the glass and the outside of the funnel. Flies will be lured inside by the scent, and they’ll crawl into the funnel, but they won’t be able to get out!
The vinegar/wine does start to smell a bit over time, since it’ll ferment, but that’s good because it’ll attract more flies! I’d suggest changing it out every few weeks.
Good luck!– Mimi
