Washington's Fourth Drought Year Is Pushing Beekeepers to the Brink

Dr. Anya Sharma · 2026-07-08

It's been a rough stretch for Washington State. We're now looking at the fourth straight year of drought conditions, and while we often talk about how this affects farmers, orchards, and water supplies, there's a quieter crisis happening right under our noses. I'm talking about the bees. Beekeepers across the state are feeling the squeeze in ways that most people don't even realize. It's not just about finding water for the hives—it's about the entire ecosystem that bees depend on surviving. When the ground dries up, the flowers dry up, and when the flowers dry up, the bees have nothing left to forage. ### Why Drought Hits Hives So Hard Here's the thing about bees: they're incredibly resilient creatures, but they're also completely dependent on their environment. A drought doesn't just mean less water—it means less nectar, less pollen, and less of the natural forage that keeps colonies healthy and strong. When forage disappears, beekeepers have to step in. That means feeding sugar syrup, providing pollen substitutes, and sometimes even moving hives to entirely different locations just to keep them alive. All of that costs money, and it takes a toll on the bees' immune systems. Weaker colonies are more susceptible to pests like varroa mites, which are already a nightmare for beekeepers in the best of conditions. Add drought stress on top of that, and you've got a recipe for colony collapse. ### The Pest Pressure Nobody's Talking About Here's where things get really interesting. When bees are stressed from drought, they don't just get weaker—they become more attractive to pests. Varroa mites, small hive beetles, and wax moths all seem to sense when a colony is struggling, and they move in for the kill. For commercial beekeepers in Washington, this means pest control isn't just a routine chore anymore. It's become a survival strategy. We're seeing more beekeepers turning to integrated pest management (IPM) approaches that combine chemical treatments with mechanical and biological controls. Some of the most effective products on the market right now include: - **Formic acid treatments** like Formic Pro, which work great in cooler weather and don't leave residue in honey - **Oxalic acid vaporizers** for late-season mite control when brood production slows down - **Thymol-based products** like Apiguard, which are gentler on bees but still pack a punch against mites - **Essential oil blends** that repel small hive beetles without harsh chemicals ### What Beekeepers Can Actually Do Look, I get it—there's no magic bullet here. Drought stress is a systemic problem, and no single product is going to fix it. But there are practical steps you can take to give your hives the best shot at making it through. First, monitor your mite loads religiously. The alcohol wash test is still the gold standard, and you should be doing it at least once a month during the active season. Second, don't wait until you see visible mite damage to treat. By then, it's often too late. Third, think about supplemental feeding earlier than you normally would. If the natural forage is gone by July, your bees need help in August, not September. And finally, consider splitting your hives more aggressively. Smaller, healthier colonies often survive drought better than large, stressed ones. ### The Bottom Line for Washington Beekeepers We're in uncharted territory here. Four years of drought is unprecedented for most of us, and the long-term effects on our bee populations are still unknown. But here's what I know for sure: the beekeepers who are adapting their pest control strategies are the ones whose hives are making it through. It's not glamorous work, and it's certainly not easy. But if you're a beekeeper in Washington right now, your job is to be more proactive, more observant, and more willing to try new approaches than ever before. The bees are counting on you, and honestly, so is the rest of our food system. Stay vigilant out there, keep learning, and don't be afraid to lean on your local beekeeping association for support. We're all in this together, and the more we share what's working, the better off we'll all be.

The prolonged drought hammering Washington’s apiaries for a fourth consecutive year has forced beekeepers to rethink every input, from supplemental feeding schedules to mite control calendars. When colonies emerge from winter already weakened by poor forage, the last thing you need is a chemical treatment that stresses them further. That’s why many commercial operations in the Pacific Northwest are shifting to integrated pest management, prioritizing oxalic acid vaporization during broodless periods and drone brood removal before thresholds spike. At the same time, equipment sanitation—scorching frames or freezing drawn comb—has become as critical as the miticide itself, since reinfection from contaminated boxes can undo weeks of careful work. If you’re weighing whether to rotate between amitraz and formic acid products, or debating the right timing for a thymol-based application, this guide breaks down efficacy data and application windows side by side. The state’s 2023 honey crop dropped nearly 18% compared to the five-year average, and with every hive loss costing between $300 and $500 to replace, choosing the right pest control product isn’t just about killing mites—it’s about preserving the genetic lines and stored fat reserves that carry colonies through the next dry spell.
