Bug/spider bite

by Andra
(California )

I'm not sure if mine is a bed bug bite, I'm almost certain it's some type of bug or spider bite. It's 6 dots in a circular pattern with one dot in the middle. I've had it for about 7 days now and it seems to be dying out now that I've been applying Bactine spray on it. It was very itchy, red with irritation even though I didn't scratch it and mildly puffy (probably due to whatever the poison was from the spider). Even though it's getting better I would like to know what this bug or spider was that bit me. Thank you!

Sincerely,
"I got bit!"

Thank you for sharing the details and the picture. Based on the description and the image, here’s some thoughts:

Could This Be a Bed Bug Bite?

Bed bug bites are typically small, red, and itchy, often appearing in a line or cluster. However, the circular pattern with a central mark shown in your picture doesn’t fit the typical pattern of bed bug bites.

Is It a Spider Bite?

The circular pattern and central puncture mark could indicate a spider bite, as spiders sometimes leave distinct marks where their fangs penetrate. The redness, swelling, and itchiness align with a mild reaction to venom, which spiders use to immobilize prey.
Most spider bites are harmless and heal on their own with proper care. Since you’ve been treating the bite with Bactine spray and it’s improving, it’s likely not from a medically significant spider, such as a brown recluse or black widow, which often cause more severe symptoms like spreading redness, intense pain, or ulceration.

What Else Could It Be?

While spiders are a possibility, other culprits could include:
- Ants: Certain ants, like fire ants, can bite or sting in a circular pattern.
- Other insects: Some biting insects (like mites or fleas) could create clustered marks if they bite multiple times in the same area.

What You Can Do

1. Continue Current Treatment: Keep applying Bactine or an antiseptic to the area. Over-the-counter hydrocortisone cream or an antihistamine can help with itching if needed.
2. Watch for Changes: If the redness spreads, becomes more painful, or develops signs of infection (like pus or increasing swelling), consult a healthcare provider.
3. Prevent Future Bites: Inspect your home for potential spider habitats or insect issues and address them to avoid further bites.

It’s hard to determine the exact culprit, but your bite seems to be healing well, which is a good sign.

Take care,
