Sentinel Moth Trap Strategy

Q: How can I prevent a future moth infestation?

After what seemed to be 6 months of battle with an indianmeal moth infestation, I am either in a lull or I’ve won the war.

I just don’t want to go through this again. So my question is about some form of prevention?
Just like before, I won’t use poisons or pesticides, I insist on a natural / organic approach. But I am not sure what to try.

I had read about using sentinel traps but I don’t recognize the brand name. How are they different from the pheromone sticky moth traps I’ve been using.

Thanks for your help, I used www.moth-trap.info to figure out how to beat the meal moths in the first place.

A: Use a sentinel moth trap strategy

Margaret,
Thanks for letting us know that we helped you win your battle. It’s our goal here to get accurate information for fighting a indian meal moth Plodia interpunctella infestation from larvae through adults.

Regarding prevention, we agree that there is no need to risk poisonous pesticides. At the same time we have to recognize that the moth invasions 95% of the time originate with the food we bring in to our homes. Because of this, prevention really doesn’t work (we all need to eat!).

Instead we need to focus on early detection of an emerging moth invasion. Early detection is accomplished by keeping a single early detection trap close to your food storage area. That single early detection moth trap is called a sentinel moth trap. So it isn’t any particular brand of moth trap ( you can continue using which ever brand moth trap you already stocked up on).

Most important when it comes to early detection through a sentinel moth trap is keeping the pheromone lure fresh… Many times I have gone through secondary infestations and would go check my sentinel trap only to find that the date on the trap was 9 months ago, 3 times too long, and the pheromone had dried out. So set reminders and keep the lures fresh!

So you had the right idea using a sentinel strategy, only it’s not a brand name, it’s the name of an approach to Integrated Pest Management IPM.
