I have monarch butterfly larvae stripping all leaves off my young lime tree. I hate to kill butterflies, but I want my lime tree to grow. What do you suggest?

Answer:

Natural Guard Caterpillar Killer Spray with Bt can be used to treat for worms and caterpillars as soon as they are first noticed, then repeat at five (5) to seven (7) day intervals while they are active. The mix rate is 2 fl. ozs. per 3 gallons of water (4 tsp. per gallon) for a handpump sprayer or hose-end sprayer.

Apply more frequently to control heavy infestations and be sure to apply thoroughly to the top and bottom of foliage. Please review the product label for more information.
