I see these webs all over the ground in the field where I walk my dog. Do I need to worry about either of us being bit by what created it?

Funnel Web

Dear Susan,
This is a Funnel Web, probably from a Grass Spider in the genus
Agelenopsis.  Of the Funnel Web Spider family Agelenidae, BugGuide states:  “For this family of spiders, the web is a horizontal, sheet-like web with a small funnel-like tube off to a side (or for some species, the middle of the web). This funnel is what the family is named for, and is used by the spider for hunting and protection. The spider will lay in wait in the funnel, and when an insect flies into, or lands on the web, the spider will rush out, very quickly check to see if it is prey, and if it is prey, bite it. The venom is fast-acting on the prey, so once the prey is subdued (within a second or two), the spider will drag the prey back into the funnel (for safety while eating, and to prevent other insects from recognizing the danger that lurks on the web…)  Depending on the species, the web may or may not be sticky. If the web is not sticky, the web will actually become tangled around the prey’s feet, ensnaring it in the web. Sometimes this may cause hardship for the spider later, because if the spider wanders across a web that is sticky… the spider may walk clumsily and become prey for another funnel weaver.  Web Locations:  The funnel web for the genera Agelenopsis and Hololena are distinctive, and often are noticed in bushes and grass, especially in the early fall mornings where the dew has collected on the web. The webs can be expansive, covering several square feet, or just small webs in the grass.”  Grass Spiders are not considered dangerous to humans or dogs.

Paper Wasp Nest

Dear Edward,
This appears to be the nest of a Paper Wasp in the genus Polistes.  The individuals in your image look very dark, leading us to believe they might be
Polistes metricus which is described on BugGuide as “Very dark–abdomen is black and the thorax dark reddish-brown with black lines. Tibiae and tarsi are yellow.”  Based on BugGuide data, the species is reported from Kansas.  Of the genus, BugGuide notes:  “Not as aggressive as Hornets or Yellowjackets. Often build nests under eaves. May be considered beneficial to gardeners (feed on herbivorous insects).”

These “things” are adhering to the stucco on the outside of the house. They are very hardy. No amount of hose spray will bring them down. I have eliminated other things like wasp nests before. Never seeing anything like this.

Mud Dauber Nest

Dear Bugged in California,
This looks to us like a Mud Dauber Nest.  Mud Daubers are beneficial wasps that are not aggressive.  There is no need to hose it away.

Hi bugman
this nest is in the eaves above the front door of my house, which is in the Seattle area.
it’s a wasp-like nest, but I’m not seeing much about black wasps?
I was planning to leave it alone but it just attacked and stung my roommate with no provocation (he was doing lawn work.)
now I’d at least like to know what they are? thanks …

Bald Faced Hornet Nest

Dear Diane,
This is a Bald Faced Hornet Nest, and like other social wasps, they will sting to defend the nest, but they are not considered aggressive.  This nest is already a considerable size with many workers that will help defend the nest.  Should you decide that you need to remove the nest for safety reasons, we would suggest getting a professional.

I live in Scottsdale, AZ and this nest was not here yesterday. What is it and should I leave it alone? I’m vegan so I will only rid it if it is dangerous! Thank you!

Mud Dauber Nest

Dear Tina,
This is a Mud Dauber Nest, the nest of a non-aggressive, solitary wasp, probably the Black and Yellow Mud Dauber, that is often found near sprinklers and swimming pools where it gathers mud with which to construct its nest.  It appears your nest is at the beginning stages of construction.  Eventually, the female Mud Dauber will add additional chambers and each will hold a developing larva and the paralyzed spiders that will provide its food supply.

We opened up our window on the second storey of our home and found this nest filled with these light green insect resembling a grasshopper. I didn’t think that they made nests so I’m not sure if my assumption is correct or how they would even get there. Any info would be really appreciated.
Signature: Thanks for any info.

Grass Carrying Wasp Nest

This is the nest of a Grass Carrying Wasp.  The female Grass Carrying Wasp constructs her nest and provisions it.  According to BugGuide:  “Larvae are fed Gryllidae (particularly tree crickets) or other Orthoptera.”
