Spring is here which means pest activity is on the rise. Termites are one of the top pest concerns for many city dwellers and rural residents alike. The infographic shows some interesting facts about termites.
Here in California, there are three kinds of termites considered pests including subterranean termites, drywood, and dampwood termites. The Formosan termite is one kind of subterranean termite found in California, although in limited areas.
Treatments differ for each type of termite, but there are many things you can to reduce infestations. This includes removing wood piles and scrap wood around the home, keeping substructures dry and well ventilated, and finishing exterior wood with...
If you are puzzled by curling leaves on plants in your garden or landscape, you may need to do some detective work to figure out the cause. Curling leaves can be caused by many problems, including insect damage, disease, abiotic disorders, or even herbicides.
Snails and slugs can be destructive pests in gardens and landscapes when they devour entire seedlings or chew holes in leaves, flowers, fruit, and even the bark of plants.
Manage these pests by getting rid of their hiding places, setting up traps, or planting resistant plants.
For more information about effective ways to manage snails and slugs, read the newly revised Pest Notes: Snails and Slugs by Cheryl Wilen, Area IPM Advisor, San Diego, Orange, and Los Angeles counties; and Mary Louise Flint, Extension Entomologist Emerita, UC Davis and UC IPM.

Most disorders impacting landscape trees result from abiotic (non-living) disorders rather than attacks from biotic (living) pests like plant pathogens, insects, and vertebrates. Damage caused by abiotic and biotic disorders can appear similar, making diagnosis difficult at times. For example, discolored leaves on a Ficus nitida tree could be due to drought stress, a fungus, or a nutrient toxicity or.../span>
Finding freshly dug mounds of soil in the garden, lawn, or landscape might be a sign of gophers or moles. Their mounds look similar and are frequently confused for each other.
Figure 1 shows a mole mound, which usually is volano-shaped with a circular margin. Figure 2 illustrates a gopher mound and the characteristic crescent shape and plugged opening. Actual mounds may look slightly different from these pictures, but the descriptions are typical of the two vertebrates.
The burrowing activity of both moles and gophers can damage plant roots by dislodging and drying them out. Mounds themselves can be an aesthetic problem in turf and landscapes, but they can also be tripping hazards. Both species eat plant material, and in...
