The most important thing to remember when treating for mosquitoes is that they hang out on the underside of leaves and shrubs. You should treat all shrubs, bushes and trees, remembering to not only treat the main bush or shrub but also the underside of the leaves. Mosquitoes lay their eggs in standing water, so if there are any areas of standing water where you are treating, those should be treated as well with BTI Mosquito Dunks or Altosid Pro-G Mosquito Larvicide.

Bifen XTS should not be applied at this time of year directly to azaleas for aphid and lace bug control. It is an oil based product that could damage the plants if not applied in cooler temperatures. We would recommend that you use a water base product that will be gentle on these plants and apply in the evening or early in the morning such as Bifen IT.

Direct application to the root area is best for lacebugs and aphids.

The rate for Bifen XTS for webworms is not set per gallon but by area. You will use 0.07-0.15 fl oz per 1000 square feet. This generally mixes in 1-2 gallons of water.

Be sure you are treating all the leaf surfaces until they are wet but not to the point of runoff.
