Bleach, which can kill drain flies, can also kill fruit flies, but it’s better to lure fruit flies to a liquid rather than applying chemicals, as it’s very difficult to reach them all. A more practical approach is to lure fruit flies with traps made from liquids like apple cider vinegar mixed with dish soap. This method is safer and more efficient, since it targets a larger number of fruit flies without relying on harsh chemicals that may not reach all the pests.

Adult fleas can live a few days to a couple of weeks on your couch if they don't have a host to feed on. However, flea eggs, larvae, and pupae can live much longer, even several months, with the right conditions. That is why it’s vital to eradicate them from your couch and other upholstered furniture.

Wasps are attracted to three primary things: Bright colors, food sources, and softened wood they can use for nests. They are more active in warmer months, which is when outdoor flowers and dinners also become more common. You can decrease the attention of wasps by keeping trash bins closed and avoiding bright flower colors in furniture or tablecloths.

Sort of. Hornets are a subsection of wasps with some unique characteristics (along with yellowjackets and similar types of insects). Hornets are generally rare in the United States, with European and Asian hornets the two notable examples.

Hornets tend to be significantly larger than wasps, often larger than one inch. They are also typically white or brown striped instead of yellow like many wasps. They tend to be one of the more aggressive types of wasps, which when combined with their size makes them a priority for homeowners.
