This has been going on for weeks – tiny moths in my home office. They’re attracted to my computer screens so I kill 4-6 a day, day after day. Where are they coming from??
I understand some moths eat the clothes in your closet, but my home office is downstairs in the house, away from any clothes. I don’t see them upstairs. Where are they breeding, how can I stem this nonsense? They’re quite tiny, the size of my pinky nail. My downstairs is all hardwood or tile, no running water, nothing to eat for a bug. Why is this happening?
There are moth traps that work well for eradication. They use a pheromone that attracts male moths to a glue trap. Set one up and watch the horny moths make a beeline.
The moth traps work great, but you will keep needing to renew and replace them unless you can find where the little suckers are breeding. In our case, we looked through all flour, all grains, everything in the pantry with no luck. Finally we realized that they were in the bottom of a big sack of dog food. We threw that away and bought a sealed bin to keep dog food in from now on. No more moths.
(Edit to add–they moths sometimes seem to like to breed in one place–like the kitchen–and then congregate somewhere totally different–in our case, upstairs in the bedroom. Air currents, light, who knows what makes them go where they go!)
Huh, that’s a new one for me. I can’t think of everything they could be eating. All of my flour, corn starch, rice etc are all in sealed containers in the upstairs kitchen (my office is downstairs) – I just checked. I guess I’ll try the traps, but I’d really like to know where they’re breeding.
Be aware that there are two types of common moth traps; pantry moths and clothes moths. They are inexpensive and widely available in hardware stores like Ace Hardware, Home Depot, etc.
The package will probably contain more than one trap so you can check a couple different areas to help narrow down the source of your infestation.
There are moths that live in drains. If you don’t use a sink for quite some time, the water in the drain trap evaporates, and the little flies can get through the drain and infest the house. My tenant had it happen when he didn’t use a sink for a long time. Psychodidae - Wikipedia
Ooh, interesting! There’s a two sink + bathtub bathroom right next to my office, and I don’t use the tub or one of the sinks. After reading your post, I just popped in there and ran water in that sink and the tub. I’ll try to remember to do that every few days now.
ETA: I read your wiki link, and my moths don’t look like those “moths”.
I have to say, once I tried @carnivorousplant’s suggestion and ran water in both sinks and tub in my second bath, I haven’t seen one moth these last 10 days. Thanks for the suggestion.
