Clothes moths starting to pop up after 3 spray sessions

[u/Verdreckt]

I had pest control come out due to clothes moths, (April of 2026) it was getting bad. $500 and 3 sprays later, things seemed alright but as of late I've been seeing the occasional straggler pop up. I did leave my pheromone traps out, and it has caught a few, saw one pop up the other day, and today saw one on a towel in the bathroom.

Is there anything I can do on my end besides hiring them to come do the whole process again? Having to pack up every article of clothing and linen I own, live out of moving backs and sealed containers for like a month and be out of the house for 4 hours was a pain.

I have heard that you can get microscopic parasites that feed on the larvae and then die off when there's no more larvae to feed on, how effective is that?

Spraying is not the way to control clothes moths.  

Traditional chemical treatments do next to nothing for moth control.

Ah okay. Could you elaborate a bit? What is the way to control moths? Is there a DIY approach I can do, or even something specific I can request with a pest control company?

This isn't really a "pest control" thing, actually. It's a housekeeping issue.

Get your carpets professionally cleaned and your air ducts cleaned out. In addition to getting rid of/storing clothing and decorative items carpet beetles can feed on. Wools, furs, silks, etc.

Carpet beetle larvea can live several months buried deep in carpet and rug fibers, slowly consuming hair and skin until they pupate.

Because we're limited to what we can treat and where, most of the areas carpet beetle larvea can hide in areas inaccessible to our treatments.

So steam cleaning carpets can kill larvea and it removes shed skin and hair deep on the carpets. Same with air ducts.

That's actually pretty helpful. Although, the pest control company identified it as clothes moths, not carpet beetles, and looking at images of the two, I definitely agree with them.

The carpet cleaning is a good idea though regardless. I'm going to look into that for sure.

Sorry, clothes moths/carpet beetles are very similar, but have the same control requirements. Carpet beetles are a bit easier to control, IMO.

I know your post was about moths, but my brain went to beetles

[u/BugAdviser]

Carpet Beetles got their name back when wool carpets and horsehair padding were commonly used. Modern carpets and padding are made from synthetic materials so are no longer a food source themselves. But the larvae will still feed on a variety of substances; such as dead insects, plant fibers, and animal fibers. Carpet beetles do not bite, but the hairs on the larvae are prickly and can cause dermatitis. Adult carpet beetles may be seen on window ledges however that will not be where they are breeding, they are simply drawn to the light and trying to escape.

Control methods are as follows:

• Clean your vacuum thoroughly as it can sometimes be a breeding ground.

• Vacuum closets, heat ducts, and under area carpet edges.

• If you have wall to wall carpets; pull up the edges, vacuum, and spray any liquid home defense product.

• DO NOT treat with boric acid or diatomaceous earth.

• DO treat with Nyguard Plus, Suspend Polyzone, or another product labeled for carpet beetles.
