QUESTION:
We have a well kept house that we service every two months and the only problem they have is springtails, which I sent off to Mississippi State for proper ID. The only place they have seen them is at the sink and at the back door. I have found no water leaks. The outside has flower beds around the house and no sprinklers in the yard. Any suggestions on what to do?
ANSWER:
Springtails can be one of those very frustrating insect problems. We know that they must be associated with moisture somewhere because they feed on things that grow in damp situations – fungus, mildew, algae, and decaying plant materials. They can be extremely common outdoors in damp landscape, under boards, under potted plants on the patio, under thick layers of leaf litter, mulch, or groundcover. But, it always is dampness that attracts them and indoors they can breed in wet situations. Unfortunately those damp conditions often can be hidden, and the presence of springtails could be telling us that some excessive moisture problem exists someplace that should be located and corrected.
Often it may just be potted plants, and in bathrooms this may be the reason you find them in the sink or bathtub. The springtails are attracted to the wet, rich soil in the pots, breed there and produce more of themselves, and then hop out to wander around on the sink counter, getting trapped in the sink itself by the smooth porcelain. Investigate this possibility in your account, and even move any potted plants outside for awhile to see if the springtails cease to occur. It could be a moisture problem in a crawlspace if one exists, or even under a slab where cracks or gaps allow the springtails to move up into the living areas.
The fact that one of the locations you are seeing them in is at the back door could suggest that these are originating out in that back yard, and perhaps cooling weather or recent rains caused them to move around more and even head into the structure looking for a better location to survive the oncoming winter weather. Sometimes hot, dry weather does the same thing, causing the moisture-loving insects to leave their now dry habitats and move into or under structures. You might place some glue traps around the OUTside along the foundation on either side of this door, and check in a week to see if any numbers of springtails are on the traps. Of course, make certain no other animals can get stuck on the glue, perhaps by placing the traps under something or within a trap station.
Do inspect carefully under all sinks to see if any leaking or sweating pipes are creating damp areas that may grow mildew. Inspect under the refrigerator to check for any moisture problems. If there is a basement check it for wet areas, especially around water heaters. Moisture always is the key for where they are coming from, but they may end up in dry locations that mislead you.
And, while we are on the subject of springtails I have to mention another side topic. The internet is filled with websites that talk about “Collembola Mites” and how these nearly invisible parasites will bite people and burrow into their skin. This is completely, absolutely false, and these kinds of websites are there only to justify the imagined problems that many people have where they are convinced something is eating them. First of all, mites are mites and Collembola are springtails, and as far as knowledgeable entomologists know the two Orders of arthropods have not morphed together to become some new creature. Second, springtails have no ability to “bite” or burrow into skin. These kinds of claims should patiently be countered with accurate information from ethical university websites.
