I see tons of small tiny worms climbing up the side of my house. I can’t tell if they’re coming from the ground or something else. They’re really small, white and move like an inch worm. What can they be? There has to be over 100 of them and I don’t see them anywhere else.
I’m not sure what you have crawling up the side of your house but there are plenty of possibilities. Depending on where you reside, it could be anything from fly maggots to some kind of moth larvae. Do you have nut trees close by? Nuts will many times get infested with various bugs and late in the season will hatch out the young that have fed. Most will be eaten by squirrels, rats and chipmunks but any left could be releasing the larvae you’re seeing. In all likelihood they’re simply looking for a good place to undergo metamorphosis and won’t pose a hazard to the structure. This can also happen from fly maggots as well as many other plant feeding insects. Most common in the spring and fall, larval stages need to find a place to complete their life cycle so this is quite common and “natural”.
If left untreated, these “worms” will probably disappear in a day or two. But they won’t really be gone. They’ll probably be spinning their cocoons in which they’ll live a few months as they change to adults. At this time a good spraying with some CYONARA RTS will knock them down and the invasion will be over.
I also recommend a good inspection of the surrounding area to make sure there isn’t something dead or decaying that’s leading to the masses you’re seeing. If you keep seeing them over a period of a few weeks, treat again and be sure to cover a larger area. There could be something down in the mulch or just under the top soil that’s feeding them and if you treat the ground good, you should be able to stop them before they emerge and start their exodus.
