Pest Control FAQs, answered by experts

Hornets are attracted to bright colors that look like flowers, including purple, pink, white, green, and yellow. They are least attracted to dark colors, such as blue and black. 

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.

Termites, carpenter ants, and wood-boring beetles can move from wood furniture to other areas of your home. If you notice signs of bugs in wood furniture, it's best to remove and isolate it for treatment. Remember that it can be difficult to identify which type of pest you are dealing with, and they can already be in areas of your home.

If DIY methods don’t work or you don’t know which pest it is you should contact an exterminator if you are showing signs of wood-eating pests to prevent further damage.

Scorpions are repelled by strong scents like lavender, cedar, peppermint, and cinnamon. Applying essential oils of these scents mixed with water around your home's perimeter and entry points can act as a mild, chemical-free deterrent. In addition to scents, scorpions also tend to avoid well-lit areas, preferring to hide in dark, cool, and damp places during the day. However, it's important to note that these methods are not fully effective on their own and should be combined with other preventative efforts, such as sealing any potential entryways into your home.

First, you’ll start noticing fewer flying termites in the air. Second, you’ll see fewer ground-based termites near the entrances to their colony, and eventually none at all. Third, if you have access to part of the nest like mud tubes, you can scour away a section and watch it. If the tubes don’t get repaired, the nest is probably doomed. Again, it can take several weeks for termites to fully go away, depending on the type of treatment.
