When it comes to protecting your family, some of the biggest threats are the smallest in size. Across America, certain insects pose serious dangers, from painful bites and stings to the spread of harmful diseases. Knowing which insects to watch for and how to safeguard your loved ones can make all the difference. These are America’s twelve most dangerous insects and how you can protect your family from them.
1. Mosquitoes
Mosquitoes are among the deadliest creatures on Earth, responsible for over 725,000 deaths globally each year. In the United States, these tiny but dangerous insects primarily spread diseases like West Nile virus, dengue fever, and, less commonly, Zika virus. Most active during dawn and dusk, mosquitoes pose a significant health risk. To stay protected, use EPA-approved repellents containing DEET, picaridin, or oil of lemon eucalyptus. Prevent breeding by removing standing water around your home, and consider using mosquito nets when sleeping outdoors.
2. Black Widow Spider
Recognizable by the red hourglass shape on their abdomen, black widows are found throughout the US. Their venom is neurotoxic and can cause severe pain, muscle rigidity, vomiting, and sweating. While rarely fatal, their bite requires immediate medical attention. To avoid encounters, wear gloves when working in cluttered areas, sheds, or woodpiles where they often hide.
3. Scorpions
The Arizona bark scorpion is the most venomous in North America. Its sting can cause severe pain, numbness, tingling, and, in rare cases, paralysis and death. They’re most common in the Southwest. To protect yourself, shake out shoes and clothes before wearing them, and consider using black lights to spot scorpions as they glow under UV light.
4. Fire Ants
These aggressive ants swarm and sting simultaneously when their mound is disturbed. For most, the stings are just painful, but for some, they can trigger severe allergic reactions. They’re prevalent in the Southern US. Avoid bare feet in fire ant territory and treat lawns with appropriate insecticides if infested.
5. Cow Killer (Red Velvet Ant)
The “cow killer,” also known as the red velvet ant or eastern velvet ant, is actually a species of parasitoid wasp. Female cow killers are wingless and covered in dense, bright red or orange hair, often resembling large ants. Renowned for their intensely painful sting, which inspired their dramatic nickname, these wasps are not actually lethal to cows or humans, but their sting is excruciating. They inhabit grassy areas, meadows, and sandy regions across the eastern and southern United States. To avoid painful encounters, wear closed-toe shoes when in these environments and refrain from handling these striking yet formidable insects.
6. Hornets
Hornets, especially the European hornet and bald-faced hornet, can deliver painful stings and are more aggressive than bees. They can sting multiple times and may attack in swarms if their nest is threatened. Avoid wearing bright colors or floral patterns that might attract them, and never attempt to remove a nest without professional help.
7. Bees
While crucial for our ecosystem, bee stings can be life-threatening for allergic individuals. Africanized honey bees, found in the Southwest, are particularly aggressive. If you encounter bees, remain calm and slowly walk away. If you’re stung and experience symptoms of anaphylaxis, seek immediate medical attention.
8. Wasps
Paper wasps and yellow jackets are common throughout the US. They can sting multiple times and become more aggressive in late summer and fall. Keep food covered when eating outdoors to avoid attracting wasps, and avoid swatting at them, as this may provoke them.
9. Assassin Caterpillar
While not native to the US, this caterpillar has been spotted in Florida. Its spines deliver a potent venom that can cause severe pain, headaches, and, in extreme cases, internal bleeding. When engaging in outdoor activities, consider wearing long sleeves and gloves to minimize the risk of accidental contact. Refrain from touching unfamiliar caterpillars, especially those with bright colors or spines, as these features often indicate potential toxicity.
10. Blister Beetles
These beetles secrete cantharidin, a toxic substance that causes painful blisters on skin contact. They’re found throughout the US, often in alfalfa fields. Wear gloves when gardening and avoid crushing these beetles on your skin, as this can release cantharidin and increase the risk of blistering.
11. Asian Giant Hornet
The Asian giant hornet, also known as the “murder hornet,” is native to East Asia, including Japan. This large hornet has been detected in the United States, particularly in Washington state and British Columbia, Canada, since 2019. It delivers an extremely painful sting and can inject a significant amount of venom. While a single sting is unlikely to be fatal to a healthy adult, multiple stings can be dangerous. Exercise caution around large wasps or hornets. If you encounter an Asian giant hornet, do not provoke it. Slowly and calmly distance yourself from the area.
12. Kissing Bugs
These blood-sucking insects can transmit Chagas disease, which can lead to serious heart and digestive problems. They’re found primarily in the southern US. Seal cracks and gaps in your home’s exterior, use window screens, and keep your yard free of debris to discourage these insects. Since kissing bugs are attracted to light, consider minimizing outdoor lighting near sleeping areas.
