Vermont is home to a few species of venomous spiders, including the northern black widow and the brown recluse. While these spiders do possess venom that can be harmful to humans, they are not commonly found in the state.

How to prevent spider bites in Vermont?
- Keep your home and outdoor areas clean and clutter-free to reduce spider habitats.
- Use a vacuum to remove spiders and their webs from indoor areas.
- Seal cracks and crevices in your home to prevent spiders from entering.
- Use screens on windows and doors to keep spiders out.
- Wear long sleeves, pants, and gloves when working outdoors, especially in areas where spiders are commonly found.
- Shake out clothing and shoes before putting them on, especially if they have been stored for a while.
- Use insect repellent containing DEET when outdoors in areas where spiders are prevalent.
- Keep outdoor lights off or use yellow or sodium vapor lights, as they are less attractive to insects, which spiders feed on.
- Remove debris, woodpiles, and other potential spider habitats from around your home.
- If you suspect a spider bite, seek medical attention immediately.
How to treat a spider bite in Vermont?
If you are bitten by a spider in Vermont, it is important to first identify the type of spider if possible. Most spider bites are harmless and can be treated at home with the following steps:
- Wash the bite area with soap and water to prevent infection.
- Apply a cold compress or ice pack to reduce swelling and pain.
- Elevate the affected limb if possible.
- Take an over-the-counter pain reliever such as ibuprofen or acetaminophen if needed.
- Keep the bite area clean and dry.
- Monitor the bite for signs of infection such as redness, warmth, swelling, or pus.
If the spider bite causes severe symptoms such as difficulty breathing, chest pain, muscle cramps, or a severe allergic reaction, seek medical attention immediately. It is also recommended to seek medical help if you are unsure of the type of spider that bit you or if you develop any concerning symptoms.
What is the peak season for spider activity in Vermont?
The peak season for spider activity in Vermont is typically during the late summer and early fall months. This is when spiders are most active as they search for mates and build webs to catch prey before the colder weather sets in.
How to identify poisonous spiders in Vermont?
There are only two poisonous spiders in Vermont that you should be aware of: the black widow and the brown recluse. Here are some tips on how to identify them:
- Black Widow: Black widow spiders are shiny black in color with a distinctive red hourglass-shaped marking on their abdomen. They are typically around 1.5 inches in length and have a round, bulbous abdomen. Their webs are messy and irregular in shape.
- Brown Recluse: Brown recluse spiders are light to dark brown in color and have a violin-shaped marking on their back. They are around 0.5 inches in length and have a small, oval-shaped body. Brown recluse spiders usually have six eyes arranged in pairs.
If you come across a spider that matches the description of either of these species, it is best to exercise caution and avoid contact. If you suspect that you have been bitten by a poisonous spider, seek medical attention immediately.
