The small creatures appear to be springtails, common nuisance pests where it's excessively moist. Fortunately or not, springtails feed on fungi, algae, and/or decaying vegetation.
Thus, the key to getting rid of springtails indoors requires a bit of detective work followed by eliminating the reason for the moisture.
If the springtails are only on the kitchen counter, begin by directing a fan at the area while you search for the moisture source. To effectively dry out the area, and the springtails, run the fan for 24 hours daily.
Indoors, high-moisture areas in kitchens such as around or near the sink are the first places to investigate, especially the back-splash and the surrounding counter
If not there, other moisture sources include these:
- In and around plumbing, especially connection points.
- Outdoor plantings or firewood within 12 inches and/or resting against the exterior wall.
- Mulch or leafy debris against the base of the exterior wall.
- On occasion, outdoor populations build-up from continuing rainy weather such as we've had recently. Then, springtails can markedly increase their outdoor populations and migrate indoors via cracks and crevices around doors, windows, and gaps where utilities enter the structure..
If all else fails, consider hiring a pest control company.
