Alfalfa weevils

Alfalfa weevil adults are about 3/16 of an inch in length, brown with a dark brown stripe down the back.  Weevils are a group of beetles that often have a long snout.  Larvae are legless, plump and yellow to green in color with a dark head. Both adults and larvae have chewing mouthparts.

Females lay eggs in the stems of alfalfa where the larvae develop throughout the spring.  Pupation takes place in the soil. There is one generation per year and the adults can survive 10-14 months.

Host plants include alfalfa, vetch and various clover.

So why am I, an urban agent, writing about what seems to be a field crop pest?  Well, these little guys and gals have been emerging from overwintering sites and making their way into homes and other structures.  I spoke with a Master Naturalist in Williamson county who said that someone brought in a bag full that was collected from the inside of a home.

If you are dealing with alfalfa weevils invading your house, work on exclusion techniques.  Some ideas include:

  1. reduce outdoor lighting at night or use yellow bug bulbs
  2. make sure weather stripping is in good repair around doors & windows
  3. make sure screens are in good repair
  4. seal any crack & crevices with sealant that will expand with temperature change we get throughout the year
  5. seal any pipe/ wire penetrations
If you want, you can do an outdoor treatment with pesticide around the foundation to create a barrier.  Indoor pesticide treatments are unnecessary.  Clean up any weevils found indoors with a dustpan and broom or a vacuum.

FREE Webinar Friday, April 4, 2014 1PM CDT: Get TickSmart: 10 Things to Know, 5 Things to Do

All Bugs Good and Bad Webinar Series: Get TickSmart: 10 Things to Know, 5 Things to Do

With more ticks in more places than ever before, there's never been a more appropriate time to raise your tick literacy.  Tick encounter rates aren't creeping up... they're soaring.  Just one species, the blacklegged tick (Ixodes scapularis), transmits Lyme disease and at least 4 additional dangerous infections across a wide swath of the United States.  This tick is not your "regular" tick, although it may be the most common. 

To stay TickSafe and disease-free, there are 10 things you must know about ticks these days.  Once you know about those things, there are 5 top TickSmart actions you can and should take.  No more "hmmms," "uhhhhs," or "I'm not sure."  The Get TickSmart campaign hopes to fast-track your access to knowledge and resources that empower you to be proactive and protected

This webinar will be presented by Dr. Thomas N. Mather, Professor & Director, Center for Vector-Borne Disease and TickEncounter Resource Center, University of Rhode Island and moderated by Shawn Banks, Extension Agent Agriculture-Horticulture, NC State University Cooperative Extension.

A Lesson in IPM

Last weekend was a learning lesson for the boy.  When I went into his room after his nap, he told me that he had a bunch of ants on the other side of his bed.  He wasn't panicked, but just stating a fact.  I go look on the other side of his bed and discover a bunch of acrobats ants crawling on the floor, the windowsill and the wall.  I told the boy to come over and look at the ants.  He did.  I asked why he thought they may be all over the place.  He wasn't sure.  I asked if it could be because the location the ants were crawling around in was the same location he goes to hide and eat candy in his room.  He thought that I had made a good conclusion.  I informed him that there will be no more food (including candy) in his room.  We then got out the vacuum and sucked up the ants and food crumbs and then played pirates and policemen.
