Mold Mites In Homes

mold/grain mite

The tiny white/tan "bugs" that people find swarming over surfaces often turn out to be mold mites (also spelled mould mites). Since the mites are also attracted to warm surfaces they may appear to be infesting electronics like computers and televisions as well.

When found in homes mold mites are usually associated with some type of moisture issue which has caused mold growth. The moisture source can be as simple as a leaky pipe or as difficult as a leaky roof or foundation. The mites feed on the mold and populations can grow rapidly. The mites are tiny, and usually white or tan in color, and have very long "hairs", or setae (see photo above).

See Mold Mites In Homes for additional life history and control information.

Mold mites are sometimes called "grain mites" because they also commonly occur in grain storage warehouses on the surface of grain sacks.

The mites are harmless. They don't bite or cause structural damage. However, the long body hairs can contribute to indoor allergens when the broken-off hairs become airborne. The mites are generally an indication of a mold/moisture problem which is usually more of a concern than the mites themselves. No treatment is needed other than reduction in moisture.

See the "Mold Mites In Homes" article cited above for more information.

What are these BIG black ants in my house?

carpenter ant In early spring or late winter people often encounter these large black ants in homes. These big ants are different than the more common small, brown "nuisance ants" that plague kitchens. The big ants are called carpenter ants ( Camponotus spp .) and unlike their smaller cousins, nest above ground in cavities. Nest building and cavity expansion by these large, powerful ants can cause damage if nests occur in our homes. Most of the ants you find in homes are small, less than 1/4", and brown. There are several species of small brown ants that can nest in our home's walls or nearby soil and enter homes in search of food and water (see House Ants for identification and control). Nuisance ants are just that, a nuisance. They won't damage your home and pose no health threat of any kind.  There's another ant, however, that occasionally is found in homes that is much bigger (1/4"-5/8"), darker in color, nests in the walls, floors and c...

These bites are from a tiny insect called a thrips (the name is always plural; one thrips, many thrips). Thrips normally feed on plants with very sharp, knife-like mouthparts but some are predators of other small insects or mites. If they happen to land on us they can bite causing a sharp, stabbing pain. The bites are annoying but completely harmless and are more common in mid- to late summer. Unfortunately, insect repellents don't work against thrips. Continue reading to discover ways to avoid thrips bites at our 'Bugs website . drawing showing feathery wings Thrips can be important plant pests where they damage leaves and in some cases even infect plants with a virus. Greenhouse growers in particular often treat their crops with insecticide to prevent thrips damage. ___________ ...

The question below represents a number of similar questions we've gotten about "bites" that mysteriously appear in the morning. In this case, the bites started shortly after moving into a newly built home.  Question: What's Causing the Itchy "Bites" - After Moving Into New House? itchy "bites" "We recently built a new home from the ground up. The process took a little over a year but we finally moved in this past October (2009). Not long after we moved (maybe a month?) I started to experience mysterious bites mostly along my thigh area down my leg to my ankle or foot (see photo). These were happening at some point in the night and every night because I am certain they were not there the previous day.  We immediately thought bed bugs since our mattress was stored in a garage during the build, wrapped in fabric but not plastic. We instantly got rid of the mattress, thoroughly cleaned the entire bedroom and home, then continued to sleep on ...
