" DALLAS — A species of ant that has ruined sewage pumps, fouled computers and made it difficult for homeowners to enjoy their yards has a new target: the honeybee.

The range of the so-called Rasberry crazy ant has more than doubled in the past year, creating a swath in 11 counties beginning near Houston and moving north, scientists say.

Given the ant's encroachment on livestock, hay bales and a few honeybee farms, some are trying to classify it as an agricultural pest, one that must soon be stopped.

"It really is spreading at an alarming rate and we need to do research now," said Danny McDonald, a Texas A&M University doctoral student who is examining the tiny creature's biology and ecology. "There's no time to wait.""


"He said he's losing about 100 hives to the ants each year. At its peak, Coplin Bee Farms had about 2,500 hives, but colony collapse disorder and Hurricane Ike reduced the business to about 600 hives.

"Everything eats a honeybee — purple martins on down to dragonflies," Coplin said. "But the invasion of these ants is 100 times worse than anything I've seen. This is something new."

Apiculturists say the Rasberry crazy ants don't appear to be interested in the honey; they're after the brood. They invade the honeycomb cell and dine on larvae. When the bees escape, the ants take over the abandoned hive and lay eggs.

Coplin said he's forced to burn the infested hive and equipment. That's cost him about $30,000 so far."

I was reading about these a while back and the local news is doing a story on them today. They are not supossed to be here yet. I am about 200 miles N. of Houston, but I saw what I thought were rasberry ants last week at one of my yards. I put on a grease barrier to try to keep them away. I am going to go look and get a closer look at these ants that I have not seen before. Couious if Gene W. on here has ran into them yet.

I'm a little further south than Derek and I haven't noticed them, but we have our share of fire ants. Had an inch of rain and that brought the little buggers to the surface.:(

I think I'll make stands for the hives (only have 2) and place each leg in a small can with motor oil. That might discourage both varieties.

Hey Walt, a better idea is to use a small layer of axle grease, vaseline or something simular close to the base of the hive stand to create a barrier they can't cross. The oil pans can create a puddle of dead bees in it.

I use 4 cinder blocks with metal tubing through the top holes and put a layer of grease close the the blocks.

Derek, Thank for the tip. I hadn't thought about the girls getting into the oil. I'll try the grease. Thanks again. :thumbsup:

In 2007 & 2008 my hives had terrible ant problems. The surface of the syrup in feeders would be literally covered in dead ants. When seeing this, I could only imagine what bacteria,virus or fungus they may be carrying.

I tried a few of those plastic hive stands that have the oil/water traps on the legs to keep ants out. Oddly they seemed to kill far more bees than ants and while I never did figure it out, the ants still got into the hives. I ended up throwing them away

Then I started using Vaseline around the tops of feeders and where I had ant problems. At this time, I have no ant problems to speak of. Early this spring I saw some activity but a month later nothing.

:thumbsup:

I this the same ant as the Argentine ant that's been in the news?

I like the grease idea on pipe supports. I hadn't thot about using it around my hives but use it every time I go camping in the MH to put around the elect shore power line and the water hose going into the MH. It works!

Different but simular. They're cousins

We had fire ants in our yard & tried some diatomatious earth ....had to reapply after the rain, but after 3 applications in a couple of weeks, they moved on! No fumes, it's a mechanical killer of insects...it kills insects when they crawl on it.
It's also worked for fleas, roaches & ants in the house. I put it under my hives last year to discourage SHB ....
