Moth infestation prevention...How?

Moth infestation is something I currently need info on. I just moved to a different site with in my School district, and the moths were everywhere. I live in Colorado Springs, CO. Any suggestions?  

  • Building? Home? I'm assuming you mean interior. First, you need to find the source of how their getting in. There has to be a breach in your exterior. Check your HVAC system, windows etc. Once you figure out where the breach is, get back to me.


  • Outside of the cleaning, I've used small cedar chips where the infestation was.   Though I don't have a home infestation, I do keep the chips in my home closets.  A hardware store or a local tree trimmer will have some (fresh).   Good Luck.    

  • Not sure what type moth you have but I have run into 2 varieties. One feeds on wool and the other feeds on starch and/or corn products. I manage a large daycare and found the moths breeding in some of the arts and craft items like indian corn used for decorating and in some of the teachers stockpiled lunch items that come in foil packs like lipton noodles, etc. The Indian corn or similar will cause you great infestation. The only way to combat is to remove the food source and they'll go away. In main Admin buildings I found the other variety that feeds on wool like carpet, drapes, etc. The cure for this is to make sure there's no moisture from leaks and thorough vacuuming to remove eggs that are laid in the flooring or drapes. This type moth will literally eat the carpet from under your feet. Hope this helps your cause.

  • As Operations Director for a large county school district in East Idaho I had a large infestation. We tried the cleaning, patching holes etc but it was not solving the problem.

    A large infestation may require professional help.

    Effective pest control requires some knowledge about the pest and it habits. The first step is to identify the pest correctly; the second step is to learn about it lifestyle. Your local University Extension Office can often help your identify your pest. They also publish fact sheets on specific pests in your area.

    If you do go for professional help, get quotes from three companies.

    You should get a free survey and confirm the cause of the problem.

    It should tell you what treatment will be used and how long it will need.

    You should get a report to say the work has been carried out and is complete.

    We have long cold winters in Idaho and that, with conciencious cleaning practices is what finally solved our problem.

    Good Luck


  • A little more information may be helpful. May I suggest you first identify the species of moth. If your life was moth free until recently you may want to evaluate what has recently changed. Some moths eggs can remain dormant and will not hatch unless subject to higher humidity levels (50-55%RH). Once they start hatching and reproducing they can infest a variety of organic material. A trained expert will need to help you determine if this is the case. I am tempted to recommend pheromone traps but if you are not well versed in pest control procedures this could make matters worse.

  • Yes, species of moth is important.  Get it ID'd!  If they are very small, ~1/4" or so, tan/gray, and lazy fliers, you may have "Indian Grain/Meal Moth."  If so, they probably have arrived in bird seed, pet food, popcorn, or some kind of organic grain human food product like rolled oats or cereal.  They will be interested in any products made of grain, any seeds, nuts, anything made with flour, etc.  Check everyplace food is stored, including dry pet food.

    These guys can be very hard to get rid of, and the larvae are happy to eat their way through cardboard boxes and plastic bags.  It may be necessary to take away their food supply by putting all food which might interest them into tight tin, glass, or plastic containers.

    Good luck!

  • The very first step is identification. Traps are useful if you cannot catch one.

    We had a special problem in a wharehouse that had moths.

    The building was full of thousands of rolls of carpet and that appeared to be the source.

    Once we put up traps and identified the moth, we found it was a moth found in peanuts. After discovery we found a room where peanuts and popcorn was stored in a small room with Christmas leftovers. The solution was simple and cheap.

    Throw away the stale peanuts.

    Problem solves and customer very happy.
