Beekeeping Pest Control: What Cornell's New Spanish-Language Course Reveals

Dr. Anya Sharma · 2026-10-11

When Cornell Cooperative Extension announced it's offering its popular beekeeping basics course in both English and Spanish, it wasn't just a win for accessibility. It was a reminder that beekeeping is booming in the U.S. — and so are the pests that threaten our hives. If you're one of the thousands of new beekeepers trying to keep your colonies healthy, you already know the struggle. Varroa mites, small hive beetles, wax moths — they're relentless. But here's the thing: with the right pest control products, you can tip the odds back in your bees' favor. Let's talk about what actually works. I've spent years comparing products and talking to beekeepers across the country, and I've seen what ends up in the trash versus what gets reordered. So whether you're just starting out or you're looking to upgrade your pest management game, here's the straight scoop on the best beekeeping pest control products in the U.S. market right now. ### First, Know Your Enemy Before you buy anything, you need to know what you're fighting. The big three in most American apiaries are: - **Varroa mites**: These tiny vampires attach to bees and spread viruses. They're the number one killer of colonies. - **Small hive beetles (SHB)**: These pests lay eggs in the hive, and the larvae tunnel through comb, fermenting honey and making a mess. - **Wax moths**: Their larvae eat wax, leaving behind webbing and ruined frames. They're often a secondary pest, moving in when a colony is weak. Once you know what you're up against, you can choose the right product. Here are my top picks for each. ### Varroa Mites: The Silent Threat Varroa mites are public enemy number one. If you don't control them, your colony will likely die within a year or two. The good news? There are several effective treatments, and rotating them is key to preventing resistance. - **Apivar (amitraz)**: This is a slow-release strip that stays in the hive for 42 days. It's highly effective and easy to use. Around $30 for a 10-pack. Just remember to remove the strips on time and avoid using it during honey flow. - **Oxalic acid vaporization**: This is a favorite among hobbyists. You'll need a vaporizer (about $150) and food-grade oxalic acid (cheap). It's organic-friendly and works great when the colony is broodless. But be careful — it's caustic stuff, so wear a mask. - **Formic Pro**: This is a pad-based treatment that kills mites and is safe to use with honey supers on (though check local regulations). It's a bit pricey at $25 for a 10-pack, but it's worth it for the convenience. ### Small Hive Beetles: The Slimy Invaders Small hive beetles are a pain, especially in the Southeast where it's humid. They love weak hives, so keeping your colony strong is step one. But when they show up, these products help. - **Beetle Blaster**: This is a trap that sits at the entrance and catches beetles as they try to enter. It's about $20 and works without any chemicals. I've seen it reduce SHB populations significantly in apiaries in Georgia and Florida. - **CheckMite+ (coumaphos)**: This is a chemical strip that also targets varroa, but it's specifically labeled for SHB in some states. It's strong stuff, so use it as a last resort and follow the label exactly. Prices vary, but expect around $40 for a 10-pack. ### Wax Moths: The Opportunists Wax moths are like the vultures of the beekeeping world. They move in when a hive is stressed or dead. Prevention is the best medicine, but if you've got an infestation, these products can help. - **Certan (Bacillus thuringiensis)**: This is a biological control that you spray on frames. It's safe for bees and specifically targets wax moth larvae. A 250ml bottle runs about $25 and treats a lot of frames. - **Para-moth crystals**: These are used for storing frames, not for active hives. They kill wax moths in stored equipment. A 1-pound bag is around $15 and lasts a long time. Just keep it away from your bees! ### The Bottom Line Pest control isn't about nuking everything — it's about integrated pest management (IPM). That means monitoring, using the least toxic option first, and rotating products. And don't forget: strong colonies resist pests better than weak ones. So keep your queens young, your hives ventilated, and your bees well-fed. One more thing: Cornell's course in Spanish is a great reminder that beekeeping is for everyone. If you're a Spanish-speaking beekeeper, check it out. And if you're not, maybe share it with a friend who is. The more educated we all are, the better we can protect our bees. *Prices are approximate and may vary by retailer.*
