Lady Bugs Get the Job Done
Have you ever wondered what lady bugs eat? They actually eat other insects and are a fantastic form of natural pest control. Their diet primarily consists of aphids, which are very small insects that suck the juices out of plants which, most of the time, ends up killing the plants.
Interesting side note: ants and aphids have a very interesting relationship! Ants actually FARM aphids. That’s right, they farm them. Some species of ants actually protect and nurture aphid colonies, and the aphid colonies, in turn, provide juices they create from what they suck out of the plants to feed the ants. So, if you notice you have aphids AND ants, you have a bit of an uphill battle to get rid of both species.
Thankfully (sort of) I discovered that I only have an aphid infestation in my greenhouse. I swear, it was the WEIRDEST thing. One day I went in and noticed a couple of strange looking insects on a flower on my blueberry bush. They were very localized, so I just broke off that piece of the plant and tossed it outside into the harsh winter. I wrote it off and didn’t think much of it.
That is, until I noticed that my strawberry plants were starting to form buds, and those were COVERED in those little insects I discovered earlier. After consulting with an amazing agronomy friend of mine, we officially established that I had aphids. Looking around the greenhouse, I realized, to my horror, that almost all of my fruit plants somehow were now home to hundreds - if not thousands - of aphids.
I mean, come on! Who would have thought that in the middle of winter, aphids would somehow find their way inside my greenhouse and thrive? My agronomy friend said she had seen it happen before in other greenhouses, and no one was ever really sure how all those aphids got there. She suggested a few insecticides, but I’ve been trying to take a completely natural approach to gardening. That’s when my friend reminded me that lady bugs would do the job.
I had learned at some point that lady bugs ate aphids, but I had completely forgotten about that! Then I faced my next challenge: where could I get live lady bugs in the middle of winter?
Enter: Amazon. It was actually very easy to find several people willing to ship lady bugs to me, and I settled on ordering from Bug Sales (click HERE to find their listing on Amazon). Yes, I ordered a whopping 1,500 lady bugs - I knew I had a lot of aphids and would need all the help I could get to remove them! The lady bugs shipped very quickly, and they arrived in a small box with several holes poked into it. Inside the box, they were in a plastic container filled with shavings.
I received my package in the evening, which was perfect because the instructions included with them said to first, water your garden to provide water for the lady bugs, and then second, place them in the garden at dusk or dawn. I sprinkled them on the plants that needed the most help and let them do their thing.
It was very interesting to see them during the day thriving in the greenhouse, and then at night when you went in, you would not see a single one! I also have a cute little ‘bug hotel’ (also purchased from Amazon from Niteangel Pets) so the lady bugs have some options on where they want to sleep.
After a couple of weeks, I was amazed at how well the lady bugs were doing! But, they seemed to have picked their favorite plants and stayed on those rather than flying around to other plants with aphids. I returned to Amazon and purchased more (another 1,500!).
This time around, it was a little more difficult to get them. It was slightly colder outside than the first time I ordered them, and my postal carrier saw that the box they came in was stamped with ‘LIVE BUGS’ so they did not want to leave them on my porch. Unfortunately, my local post office is open later in the day which does not work with my work schedule. Besides that, I was VERY worried about the lady bugs because one of the other instructions sent with them is that they need to be refrigerated (can be for up to two weeks, but past that you will lose them) until they are ready to be placed in your garden or greenhouse. Putting them in the fridge causes them to slow down and even become dormant. This means they don’t need food or water, but if you introduce them to heat, then they become active and need the essentials to live which are not included in their shipping container.
I was worried that my postal carrier didn’t know this and was trying to keep the lady bugs nice and warm (which is totally understandable! I didn’t even know that until I first purchased these lady bugs). I contacted the post office (after hours, again because of my work schedule), and told them the lady bugs needed to be refrigerated and because of that, it was perfectly fine to leave them on my porch. The next day when I came home I found the lady bugs on my porch, and when I first took them out of the box, I was terrified to discover that not a single one seemed to be alive or even moving. I put them in my fridge for two days while I prepared the greenhouse.
Today, I took them out of the fridge, happy to discover that they were all alive and ready to go! I put them in the greenhouse, and they are now hard at work with the other lady bugs from my first order, getting rid of my aphid issue. The other awesome thing is that the lady bugs are helping to pollinate my flowers as they waltz through them on the hunt for their next meal - I have several strawberries growing thanks to them!
I have also noticed something else very curious: I have two compost tumblers inside my greenhouse (I’m trying to use hot compost to heat the greenhouse, but that’s a story for another day). Shortly after I started adding items to those tumblers, I found myself being overrun with moth flies (also called sewer flies). They are totally harmless (and actually kind of adorable - the name ‘moth flies’ comes from the fact that they look like teeny tiny moths!). They got their other name of ‘sewer flies’ because they congregate around sewers or drains and eat - you guessed it - compost/sewage. They don’t hurt plants at all, and even though they deal in some nasty stuff, they don’t transmit any sort of diseases to humans.
So, other than being annoying, they don’t bother me. However, since adding the lady bugs to my little ecosystem, I have discovered that the moth flies have SIGNIFICANTLY decreased in numbers. While I know that correlation is not causation, I also know that lady bugs eat insects - while there is no information online that I can find that states for sure that lady bugs eat moth flies, I can’t help but think that they do!
Overall, I’m very happy with my lady bugs, and they seem equally happy with their new digs in my greenhouse. Once spring is officially here and I can open up the greenhouse, I will do so and let the lady bugs free to maybe also take up residence in my surrounding gardens. In the meantime, we will coexist together to keep the greenhouse thriving through the winter.
