Thatching ants

I live in the rural Redland area. There is a recently developinr mound of what appears to be thatching ants in my goat pasture. I want to ensure the colony does not encroach into my landscaped areas. I doubt posting the area will be terribly effective. Recommendations for extermination would be appreciated. Thank you

winged ant swarm in my bathroom

I live in Salem, and have killed a total of approximately 200 winged, very dark brown or black ants (very defined waist; definitely not termites!) in my bathroom on Thursday, April 19th, and on Friday, April 20th, 2018. These winged ants are approximately 3/16" or 5 mm long. On both days, the swarms occurred in the early afternoon, ending by about 2 pm. I am partially disabled and have been unable to identify their point of entry. The ants seemed in a hurry, and gravitating toward the window and skylight, but would fall rather easily. I was surprised to find that I could detect NO odor whatsoever upon crushing them. Do you have an entomologist who can help me identify whether these might possibly be carpenter ants, or any other species of particular concern? I do have a specimen saved in alcohol, and a few others which died naturally on my windowsill. Thank you!

Carpenter Ants

I have carpenter ants in several trees on my property. Visible signs - large weeping areas, wood pecker holes, chip piles, and trees splitting. When I cut one that has split I get piles of ants. How can I kill them/stop them from spreading to other trees? What are my options? 1 acre wooded area.

carpenter ants

I am renovating a small cabin. During demolition of the interior, I found many carpenter ants living in the wall space. Is it sufficient to just clean up the interior, or should I fumigate with an insecticide as well? I plan to remove all drywall and interior walls and replace the insulation.

outdoor ants

We have numerous ant hills and ants in our newly ( this last Spring) made flower beds. Our soil is sandy. We have mulch on the beds. The ants are small and light colored.Everyday there appears to be more. It is unsightly as the hills are quite large. Do we need to exterminate them ? Will they cause problems ? Will they try to enter the house ? If we want to exterminate them what is the best "natural" method ?

fire ants in the compost

The last time I went to put some plant scraps in my compost bin, everything in it was completely composted! It looked like beautiful fine black soil. I looked closer: it was a huge ant mound, teeming with ants.

I want to use the compost, but I don't want to transfer hoards of fire ants to my garden beds. How can I get rid of the fire ants without ruining the compost?

Also, how can I keep fire ants out of my compost bin?

Thank you for you help with these questions.
