That is, they will be eggs, larvae, or pupae—none of which can fly or sting. Nearly all of the ground nesters spend 10 months in hibernation, during which time they are completely harmless. The adults do not live in the soil. Once their eggs are laid for the season, they simply die. Again, Rusty, thank YOU! Your reply is really thorough and most helpful. Really appreciate your expertise and cheerful help!
We treated the perimeter around house as it there was some damage being done. Then we pulled up the garden with the intentions of mulching and replanting some simple shrubs. Now that everything is torn up I can see that there are active miner bees. I am find with them being there but we have to do something with the front of the house.
Is there a way I can accomplish both? Almost any shrub is fine, but ground-dwelling bees need bare soil to nest in. Any kind of mulch will likely drive them away. I am guessing that there is no ideal situation in which I can protect the bees and the house bed needs to be clear and covered with cedar mulch which is supposed to be safe and non-bothersome to insects except wood boring pests.
We have tried other natural solutions to keep the ants and termites but nothing has worked. Thank you for the feedback. If you are creative you can landscape around them but their nesting area must be bare soil. Although some species will tolerate a lose leaf pack if they can get through it easily. Your site is so informative. Here is my question. Several years ago, I noticed that I had miner bees right in the middle of my front yard—the holes cover approximately square feet of yard area.
After talking to my Orkin man, who handles insect issues inside our house, he explained to me that they are beneficial bees and that I should really leave them alone and enjoy them.
I have done just that. They are dormant now, but I have a question. I would like to put in a 10 foot diameter raised bed to plant a wild flower mix for bees and butterflies. I will simply put two circles of stone on top of each other, which will be about 8 inches high. I will not even disturb the grass underneath, but just fill with a loose mixture of topsoil, garden soil and sand, as per seed planting instructions.
My question is…how badly will my plan disrupt my existing miner bee colony? My front yard already has a mixture of 18 roses bushes, 2 Rose of Sharon bushes, and a pear tree. Will my wildflower plot hurt them in any way? As for the bees, the depth of the holes depends on the species of bee living in your yard. Some go very deep while others nest just below the surface. My guess is that 8 inches of soil over the nest will probably kill most of them, but maybe not all. If the soil is loosely packed, more of them have a chance of emerging.
Thank you Rusty for your insight. Thanks again…. This afternoon I was bitten and stung by a swarm of little bees that came out of a hole that I pulled a nasty weed from.
I had a lot of bites, only a few stings. The stings came from the bees that hung on to my clothing and were probably threatened by my actions. I think they are mining bees. I get stung every year in that area but never like today. When I do dig, there are quite a range of underground tunnels but I never see anything in them. I thought they were from ants. I have them as well. I only have problems this time of year in Northern Illinois. They were buzzing around for a long time. I would appreciate knowing what they are as I do not want to kill any pollinators.
Thanks for your help! I saw where someone said she saw mining bees for 10 days in the spring, is that when they come around? I am seeing some at our power line behind the house on the thistle flowers.
Wish I could attach a photo to this…. Some come out in spring and some come out in summer or fall. If you want me to identify it, you can email a photo to rusty honeybeesuite. I believe we have had mining bees nesting in our front planter for a number of years now.
They have never disturbed anyone, and they have been pretty much left alone. However, the planter brick beside cement steps is starting to fall apart, and my parents are blaming the tunnels built by the bees.
You could try removing the soil in the planter and putting it somewhere else. Most of the immature bees will probably not make it, but some might. Question: All I read about these bees is stating they are usually around in early spring but mine are here now and usually are here intermittently throughout the Summer. Is that normal? I have a lot of flowering plant like cat mint which all of my bee friends seem to love and wondering if they are just visiting me longer because of all the pollen and goodies.
I feel bad they have landed where they did because it is near where we walk for out hose and I am always walking on their little mounds of sand and soil. I hope I am not causing much harm to the contents of their nest. Any help to these questions would be appreciated! Thanks for this great question. I have found this so interesting and enlightening as only found out this past week that the bees I have are mining bees.
Will just leave them alone and they can enjoy their little lives here in the UK. I found a small bee which I believe is a miner bee this morning in my house.
Two of my cats were trying to eat it. I saved her and am curious what and how I should feed her, and generally care for her until spring, as it is winter and I feel if I release her outside it could be too cold, weather is currently very moody where I live.
You might try a drop of sugar syrup or a drop of honey. Still, she or he will probably feel better with something to eat. I have noticed them hanging out at my hummingbird feeders which is another reason to feeders, but I think the most important thing is to have patches of exposed bare earth with no mulch.
This is what they need to tunnel in. How long should I leave it alone for? How badly endangered are they? I am thinking to do something to help them over come that by doing something small. The best thing we can do is plant flowers or flowering trees and leave patches of earth un-mowed and untended so bees have a place to nest and a place to collect materials from the environment.
Be very careful planting blooming anythings. Make sure it has not been dipped or sprayed by any neonic class insecticide or you are simply luring the bees butterflies etc etc to their death. The stuff permeates the entire plat for up to a year. Most big box retail plants are poisoned with neonics. According to the Xerces Society, neonics have been found in trees up to seven years after application. I have a mining bee nest across the street and they are very small. I went over just a few minutes ago and I saw the queen checking on the other bees.
Every time she passed by a hole a bee would sit there at the entrance. Is this normal?!? They sound like solitary mining bees or digger bees, and they are usually quite gentle and mind their own business. They are great pollinators, so they keep the plants fruitful and productive year after year.
Sourwood makes the best honey, period! We get miner bees in our front garden yard every year and they are particularly active at the moment. We are about to have a new turf lawn laid over the area and I am worried this will prevent the eggs hatching and the new bees making their way to the surface.
Any suggestion? Hiya, we are in the UK and have dug out an area in the garden intended for a wildlife pond but whilst looking around for a few weeks for some edging bricks and a liner for it a whole colony of miner bees have moved in, perfect conditions with an exposed bank of soil for them to burrow into.
We are aware we need to leave them alone while they are active for the next few weeks but what then? Will we bury the hibernating bees alive if we lay a pool liner when activity ceases, what can we do? Could we dig them out and move them maybe? So worried for the little critters. Any help would be gratefully received. The problem is that right now they are busy collecting provisions and laying eggs for the next generation. The timetable varies with the exact species, but generally they dig tunnels in the ground.
Then, off the tunnels, they build nesting cavities nurseries where they store the provisions. Then the female lays an egg on top of the provision and seals up the cavity before she starts another. The pupae will live underground and develop until this time next year, when they will emerge from the tunnel, mate, and begin their own families. So unfortunately, once they begin, there is no good time to fix the problem. Perhaps, sooner is better than later, so they can finish off their year by laying eggs somewhere else.
Okay i think some of these comments are bull, because when i mowed over a nest i got stung 5 times. So maybe some you guys have more positive hippy bees, but mine are toxic and we will sting on sight. I have two of these nest in my yard and they are inhibiting from mowing my yard. As of the moment i am waiting for my family to all get home so i can pour sulfuric acid inside the holes to get rid of them again.
If anyone can give me a more humane way of getting rid of them be my guest. If you have large holes with multiple insects going in and out, they are not mining bees. Mining bees have tiny holes, less than a pencil width, with generally only one bee coming and going. You may have wasps, hornets, or perhaps bumble bees.
Hi my front garden and flower beds are full of mining bees. They have been around for about 5 weeks. They have destroyed my lawn. I now want to pull up my summer bedding and plant wall flowers etc but I am worried i will disturb them and get attacked.
Your advise would really help thank you. Once the adults disappear for the year, you will not get attacked when you dig up the beds because the young bees will be in their larval or pupal stages. Now that the activity has stopped in what I think is a miner bee area, how wide of an area around it should I leave undisturbed?
I need to weed and clean up in the general area to plant. I have miner bees and I was stung once when I dug into a nest. Still they are generally very docile and harmless. If you have a lot of them and want them out of a certain part of your yard all you have to do is mulch that area. All pollinators are in big trouble from neonicotinoid class of insecticides. They need our help.
Any advice on how to raise the soil up without hurting the bees they are very active at the moment or what else could be done that would accommodate these little buzzy friends would be appreciated!
Disturbing the aggregation during the active season would be the most damaging. At least wait until they become inactive 6 to 8 weeks from now and then deepen the soil, if you must. It will depend on the species. The fact that you have bare soil is what makes it so attractive to ground-dwelling bees.
I have a wall 6 ft high of Cotswold stone and this year I have a wren nesting in there and of course the usual common bees. However, yesterday I noticed the humming noise was much louder and when I went to look there were dozens of totally black bees busily going in and out. They have no other colour anywhere on their bodies. Do the mining bees who usually live underground sometimes live in walls? If you want to email a photo of the bees, I can maybe tell you more. Fabulous creatures.
It reminds me of Mt. Helens here in Washington. After the explosive volcano wiped out every living thing, mining bees were one of the first thing to colonize the soil, which was mostly comprised of toxic ash. Bees are really neat. Also leave solitary wasps alone ,too. Cicada killers look scary but they are not. They will avoiding stinging. They nest in the ground one at a time. Thanks for the great site and info about mining bees. I wish more folks would leave Nature alone and learn to appreciate the other creatures on the planet!
Rusty, I would almost venture to say I have thousands and thousands of mining bees. I live in a semi arid climate in eastern Washington so a lot of my landscaping is river rock. The bees live under the rocks. Maybe a little exaggeration, but just a little.
I just let them be. They are excellent pollinators, the best. They also sting if you cross them, but they pretty much mind their own business. I would love to have a big aggregation like that. I have for the first time mining bees in my UK garden. A few nights ago some creature had made a small hole near the entrance on the lawn. I filled it in. This morning I went to have a look and the hole was massive all the way into the nest.
Hole 70 deep and mining bees flying around. What should I do to best help the bees? We are due to get a puppy in 4 weeks and I have seen that mining bees have stung young children and are quite painful. A puppy in the garden is likely to trample on them and try and eat them and get stung. Is there a recommendation for situations such as this? I think you are over-thinking this. They are often mistaken for bumble bees, also being black and yellow summertime bees.
They are friendly, non-aggressive and typically do not sting or bite. Despite their small stature, mining bees are very important to flower pollination, especially in the mid-west region of the United States. Miner bees are most well-known and studied due to their complex nesting behavior. Miner bees are solitary, ground nesting bees that like to establish their home in well-drained soils, like clay, present in banks, hills, and road cut-outs.
They have also been found burrowing between stones of old buildings and between logs in cabins or barns. Most commonly, female bees dig a tunnel in the soil using loose earth to construct a chimney-like turret, which represents a single nest. Nests are often clustered together in close quarters but females only provide for their own nest and future offspring with no overlap in generation.
Miner bees have been known to nest in the same location for many years. After mating and establishing their nests, A. This process waterproofs a cup-like cell for the provisioning of the eggs. A single egg is laid in each cell and floats on a pollen mixture foraged by the females for about five days before hatching. The larvae proceed to consume the pollen substance and cell lining over the following three weeks.
Most mining bees emerge in spring. After waiting out the winter as dormant adults in their natal nest burrows, they emerge with the increasing warmth. The skinny, bobble-headed males are out first, and patrol manically in search of females - zigzagging around nest sites, flowers and sunlit bushes. The life of a female mining bee is tough, as she is in essence a single mum. After mating and fuelling up on nectar, she has to find a place to nest and excavate her burrow.
This is usually in sunny, bare, or sparsely vegetated ground, such as a bank or the edge of a footpath. She digs using her strong jaws to break up the soil and sweeping the spoil away with her legs. Eventually she makes a tunnel branching into several nest chambers. She stocks each of these with pollen as a food store for her growing brood, before laying a single egg inside and sealing it up. It will take her many trips to complete each cell in turn.
Willows Salix spp. Staking out a sunny patch of these flowers is a great way to look for mining bees. The Social bees stick the pollen down onto their legs with nectar or saliva, which means less is dusted off onto the flowers to pollinate them. We should be thankful to solitary bees too, since studies show they are the most efficient pollinators of our orchard fruits.
