Why are bees dying? Researchers point to a parasitic mite and the viruses it spreads, pesticide exposure and too few flowers, and each of those causes has a fix that can start in your own yard. Once you know the causes, you can plant and garden in ways that keep pollinators working and keep your harvest coming in.
You may already have a backyard garden, a few fruit trees, or plans for a homestead. Wherever you are, the squash, berries and apples you are counting on need pollination. Food security for a prepared household starts with the plants, and many of those plants depend on bees.
Start by walking your yard this weekend and noting what is in bloom. Bare stretches of lawn and gaps in the bloom calendar show you exactly where to plant first.
Why Are Bees Dying? Reading the Loss Numbers
Knowing the real numbers lets you judge the problem at its true size. Below are the survey figures, how beekeepers rebuild after a bad year, and where colony collapse disorder fits. After that come the causes, which point straight to what you can do at home.
The Survey Figures
The U.S. Beekeeping Survey asks beekeepers across the country how many managed colonies they lost each year. Beekeepers reported losing 55.1 percent of their colonies in 2023-24. They lost 55.6 percent in 2024-25. The 2025-26 loss came in at 39.9 percent.
That latest figure is an improvement. It is still about double the 15 to 20 percent loss that beekeepers consider sustainable. Some loss every year is normal. Queens fail, winters run long, and a weak colony can starve before spring. Beekeepers plan for that baseline. Losses of 40 to 55 percent push past what most beekeeping businesses can absorb year after year.
Steady Counts, Heavy Costs
National colony counts have held fairly steady even through the worst years. That surprises many people at first. The answer is that beekeepers rebuild. They split strong colonies into two, give the queenless half a new queen, and buy packages of bees to restock empty boxes.
Rebuilding works, and it costs money and time. Each split needs a queen, more equipment and several weeks of care before it grows strong. A colony that gets split also makes less honey that season. Those costs show up later in the fees growers pay to rent hives, and those fees reach shoppers.
Where Colony Collapse Disorder Fits
Colony Collapse Disorder is a pattern in which most adult worker bees vanish from a hive. They leave behind the queen, the brood and stored honey, with few dead bees in sight. The pattern drew national attention in the mid-2000s. Most losses today look different. Beekeepers find dead bees on the bottom board, heavy mite loads and colonies that dwindle over weeks. That difference is useful, because it points researchers to causes they can measure and manage.
The Causes Researchers Agree On
Understanding the causes gives you a clear list of things you can change. Researchers sum them up as the four Ps: parasites, pathogens, pesticides and poor nutrition. Each one weakens bees, and together they stack. Once you see how they connect, the household plan further down makes sense step by step.
Varroa Mites and the Viruses They Spread
The varroa mite is a reddish-brown parasite about the size of a pinhead. It rides on adult bees and breeds inside capped brood cells, where it feeds on developing bees. The feeding itself does harm. The bigger problem is the viruses the mite carries, such as deformed wing virus. Bees infected as larvae can emerge with crumpled wings and short lives.
Ask a beekeeper why are bees dying, and varroa usually comes up first. A colony can look strong in late summer and then fail over winter, when mite and virus levels peak together.
Treatments Losing Ground
Beekeepers control mites with miticides, organic acids and hive management. One of the most widely used miticides is amitraz. Federal researchers studying the heavy 2025 losses reported finding mites resistant to amitraz in the colonies they sampled. When a treatment stops working, mites rebound and viruses spread faster. Beekeepers now test mite levels more often and rotate treatments to stay ahead.
Pesticide and Fungicide Residues
Bees bring home pollen and nectar from every field and yard they visit. Residues of insecticides, fungicides and herbicides can come home with them. Some insecticides kill bees outright. Others work at lower doses, weakening a bee's navigation, immune system or brood. Fungicides are aimed at plant diseases, so it makes sense to think of them as bee-safe. Some fungicides, though, can make certain insecticides more toxic when bees meet both at once.
Shrinking Forage
Bees need a steady supply of pollen for protein and nectar for energy. Large single-crop fields bloom for a few weeks and then offer nothing. Lawns, paving and mowed roadsides offer little at any time. A poorly fed colony has fewer resources to fight off mites and viruses.
How the Causes Stack
No single cause explains every loss. A colony with a high mite load, low-level pesticide exposure and thin forage is far more likely to fail than one facing any of those alone. That is the part you can use. Your yard can ease two of the four pressures by adding forage and cutting pesticide exposure. That makes why are bees dying a question with a practical answer for any household.
Research keeps refining the picture. Washington State University researchers are studying honeybee colonies used to pollinate blueberries, a crop that relies heavily on rented hives. The work is early, and its findings are still taking shape. It reflects a wider effort to understand the specific conditions bees face on each crop.
What Bee Losses Mean for Your Food
Knowing which crops depend on honeybees lets you plan your garden and your pantry around real risk. Here is how pollination works as a business and how its costs travel to your grocery bill. Then comes the household plan that puts your own yard to work.
Crops That Rely on Honeybees
Honeybee pollination supports billions of dollars in crops each year. These crops depend on it most.
Almonds. Almond trees need cross-pollination to set nuts, and the February bloom in California draws a large share of the nation's commercial hives every year.
Apples and cherries. Most apple varieties need pollen from a different variety, and bees carry it between trees during a short spring bloom.
Berries. Blueberries, cranberries and raspberries set larger, better-shaped fruit when bees visit often.
Cucurbits. Squash, pumpkins, cucumbers and melons have separate male and female flowers, and each female flower needs several visits to grow full-sized fruit.
How Pollination Fees Work
Many growers rent hives from commercial beekeepers for each bloom. The grower pays a fee per colony, and the beekeeper trucks the hives in and out. Almond pollination fees have run close to 200 dollars per colony in recent seasons. When losses climb, beekeepers have fewer strong colonies to rent and higher costs to cover. Fees rise to match.
Growers then face a choice. They can pay more, rent fewer hives, or accept a smaller crop. Under-pollinated fruit tends to be smaller or misshapen, and less of it reaches the market. Each of those paths can nudge prices upward on nuts, fruit and some vegetables.
Staples Hold, Variety Squeezes
Wheat, corn and rice are pollinated by wind. Beans, peas and potatoes largely pollinate themselves or grow from tubers. Those staples form the base of most diets and most long-term food storage. The squeeze from bee losses lands on variety and price: the fruits, nuts and vegetables that make meals healthy and interesting.
When families ask why are bees dying and what it means for dinner, the answer comes down to these factors. Honeybee losses, pollination fees, weather and transport costs all feed into food prices, and food shortages tend to start with that kind of pressure on supply. Weigh them against your own pantry and garden. Your home harvest of squash, berries and apples is the part you control directly.
Help the Bees and Protect Your Harvest
A pollinator plan gets you fuller squash vines, heavier fruit trees and a garden that produces every season. Here are the steps that work in any yard, then the branches for suburban lots and rural land. Each step answers part of why are bees dying with something you can do.
Plant for Blooms All Season
Bees need food from the first warm days of spring to the first hard frost. Plan your flowers in three waves so something is always in bloom.
Early spring. Crocus, fruit trees, willows and dandelions feed bees when colonies are building up and little else is open.
Summer. Clover, borage, lavender, oregano, thyme and sunflowers carry bees through the main garden season and pull them toward your vegetables.
Late season. Asters, goldenrod and sedum give colonies the pollen they need to raise healthy winter bees.
Plant flowers in clumps rather than single plants, because bees forage more efficiently on a patch of one bloom. Let herbs like basil and cilantro flower after you harvest your share. Add a shallow dish of water with stones in it, so bees can land and drink without drowning. Lay in pollinator flower seeds alongside your vegetable seeds each winter, so the plan is ready when planting season comes.
Spray With Care
Start with the gentlest tool that solves the problem. Hand-pick beetles, hose off aphids and use row covers on young plants. When a spray is needed, treat only the plants with pests and read the full label first. Spray in the evening, after bees have gone home for the night. Spray before flowers open or after bloom ends. Choose insecticidal soap or horticultural oil for soft-bodied pests, since they break down quickly once dry. Mow flowering clover in the lawn before any lawn treatment, so bees are not foraging there.
Hand Pollinate Squash and Cucumbers
Hand pollination keeps your harvest on track during a slow bee week. Go out in the early morning, when squash flowers are fully open. Find a male flower, which sits on a thin straight stem. Find a female flower, which has a tiny fruit swelling at its base. Brush the yellow pollen from the center of the male flower with a small soft paintbrush. Dab that pollen onto the center of the female flower.
The flower closes by afternoon. Within a few days, the tiny fruit should begin to swell. If it yellows and drops, try again with a fresh female flower the next morning. Cucumbers work the same way with a smaller brush. Many seedless cucumber varieties set fruit without pollination, so check your seed packet first.
If You Live in the Suburbs
A small yard can feel like it barely matters. It matters more than it looks. Suburban yards sit between parks, gardens and fields, and bees use them as stops along the way. Replace a strip of lawn with a flower bed, or line your vegetable rows with herbs. A small space breeds a better gardener, because every plant has to earn its spot. Planning a right-sized garden for your family means counting blooms as well as vegetables. Buy local honey to keep nearby beekeepers in business, and you support the colonies that pollinate your street.
If You Have Land
Rural and homestead families can go further. You can keep a hive yourself or host a local beekeeper's hives on your property. Hosting is the easier start. The beekeeper handles the bees, and you get pollination, often a share of honey, and a source of advice. Keeping your own hive takes equipment, a few hours a month and regular mite checks with a sugar roll or alcohol wash. Many local beekeeping clubs run classes and mentor new keepers.
A larger property means more chores, and it also means more forage and room to place hives well away from the house. Before you add hives, check whether anyone in your household has a bee sting allergy. Learn the signs of an allergic reaction and the steps to take, and keep that plan posted where everyone can see it. Preppers who already run a survival garden will find a hive fits naturally into the same routine of planting, watching and harvesting.
