I just published a blog post on the Mosquito TNT, a trap marketed by Tougher Than Tom of Austin, Texas. Exhibit A is their misleading use of photoshopped images to convey effectiveness. I also detail the $80,800 fine the company just paid to the EPA. #mosquitoes colinpurrington.com/2025/06/toug...

Dermacentor variabilis "American Dog Tick" at left, Amblyomma americanum "Lone Star Tick" at right

Both are male, I believe - neat to see them both on the same bit of grass 🤩

Seasonal reminder that Spartan Mosquito Eradicators and Spartan Mosquito Pro Techs do not kill mosquitoes. The Mississippi company was sued for fraud but the settlement agreement allows sales to continue until Christmas. Tell your gullible uncle to buy something else. #mosquitoes #mississippi #psa

One of my best friends and a brilliant scientist, literally one of the most creative thinkers that I know, was sacked today from the NSF. He will prevail, but the world just became a slightly dimmer place. As I sit crying in my office

Here is your Monday Morning Mosquito, a winter marsh mosquito, Culiseta inornata. Pretty big for a mosquito - nearly 1/2 inch. If you look closely, there's a single yellow pollen grain on the tip of her proboscis. I found her in the Mojave Desert in an area with seeps of permanent water. #insects 🐙🌿
