Title: Need bug repelling plants in Arlington, VA
Answered by: Jimmy Mills

QUESTION:

What kind of plants are best bug repellents, and need little or no maintenance. I'm a city girl and don't like bugs (spiders)

ANSWER:

Dear Miss Muffet,

You may be relieved to learn that spiders eat "bugs." In fact, most of their diet consists of insects. The report that they favor curds and whey is an urban myth that has been perpetuated by Mother Goose among others. There are also insects (digger wasps) that carry off spiders in order to provision their nests so that their developing larvae can have something to eat. So you might say its a bug eat bug world out there.

There are numerous plants that are said to be insect repellent, and some of the active ingredients,  e.g. pyrethrins, are extracted and used as insecticides. The short list below contains some of the more often mentioned insect repellent plants, however, they are non-natives and there are no entries for them in our Native Plant Database.

Lavender (Lavandula sp)   (Images)

Rosemary (Rosmarinus officinalis) (Images)

Citronella (Cymbopopgon nardus(Images)

Basil (Ocimum basillicumImages

Believing that "the best defense is a good offense", Mr. Smarty Plants is suggesting three plants which occur in your state that might help keep the bugs at bay; Venus flytrap Dionaea muscipula (Venus flytrap), Pitcherplant Sarracenia flava (yellow pitcherplant), and Sundew plant Drosera brevifolia (dwarf sundew).
