check Ants

Despite the beneficial role ants play outdoors, ants become pests when they enter homes in search of food, water, and shelter. If ants do invade your house, don't panic. A management plan based on sanitation and physical controls can effectively reduce household ant populations while still allowing ants to play their part in the environment.  Download the Factsheet

check Aphids

Have you found drops of honeydew on your car after you've parked it under a tree? Or have you found more than broccoli when you're cutting up a freshly-picked head from your garden? You're probably dealing with aphids, a common insect in yards and gardens. Don't reach for an insecticide, though; there are straightforward ways of dealing with these small creatures without having to use pesticides.  Download the Factsheet

check Billbugs

You can prevent billbug problems by planting varieties of grass that discourage billbugs and watering your lawn as needed to keep it healthy. If billbugs are damaging your lawn, beneficial nematodes are an effective, pesticide-free solution.  Download the Factsheet

check Box Elderbugs

Living with box elderbugs may be the easiest and simplest solution you'll find. If you've got more of these bugs than you can comfortably live with, try pesticide-free techniques, such as standard cleaning.  Download the Factsheet

check Carpenter Ants

Is your home being invaded by carpenter ants? There are straightforward, pesticide-free ways to prevent carpenter ant problems, such as caulking and replacing damaged wood.  Download the Factsheet

check Crane Flies

In order to keep crane flies at bay, keep your lawn healthy by giving it adequate fertilizer and water. If your lawn has shady areas think about planting a shade-loving grass or another ground cover. Dethatch your lawn as necessary, because thatch is a perfect place for leatherjackets to grow. Crane flies are rarely serious lawn pests. Most of the time they are not abundant enough to cause permanent damage to healthy grass. If crane fly numbers in your lawn are too high (over 25 leatherjackets per square foot) treatments with beneficial nematodes can reduce their numbers.  Download the Factsheet

check Dampwood Termites

To control dampwood termites, eliminate the moist wood in which these termites thrive. Repair leaky pipes and roofs, make sure the area under your house is adequately ventilated, and remove scrap wood that is near your house. In addition, be sure that there is at least a foot between the wood portions of your house and the ground. These steps will keep your house in good repair while they minimize damage from dampwood termites.  Download the Factsheet

check Deer

It is easy to forget, especially in urban environments, that deer are wild animals with excellent survival instincts that all prey animals possess. This makes them very wary and difficult to control. And sometimes there is the other problem. Deer can become so accustomed to people that they lose their survival instincts and become hard to chase away! This also makes them difficult to control. Working with deer always requires patience and tenacity. Many times it will take a combination of approaches to get the level of control that makes you happy.  Download the Factsheet

check Fleas

Fleas can cause animals a great deal of discomfort and stress. Wash throw rugs and bedding weekly, use flea combs, vacuum, and apply nematodes to soil where your pets spend time.   Download the Factsheet

check Mice

Not a fan of mice? Keep mice out of your home by eliminating all openings larger than ¼ of an inch wide. Store food carefully and keep ivy and blackberry bushes away from your house. And remember not to use pesticides. If you do, the rodents may die inside your walls and start to exude a strong and offensive odor. Pesticides can also harm your children and pets!  Download the Factsheet

check Moles

Moles are significant contributors to healthy soil. Raking away the mounds they create is the ideal solution, but if you are too burdened by them you can replace grass with other ground covers, use castor oil, or trap the moles.   Download the Factsheet

check Mosquito Repellents

Mosquito control programs for disease prevention should first focus on eliminating mosquito breeding habitats (any standing water) whenever possible. Next, efforts should concentrate on reducing mosquito larvae in other water habitats. However, we recognize that many communities faced with West Nile virus outbreaks will begin or expand mosquito spray programs.  Download the Factsheet

check Root Weevils

In some areas, root weevils are a nuisance when they come inside seeking shelter during hot, dry weather. If weevils are bothering you inside your house, remember that they don't damage your home or your furniture, nor do they harm people and pets. Vacuum or sweep up unwanted weevils. Seal cracks and make sure windows and doors are tightly screened. If your problem is particularly serious, you may want to replace plants near your house with varieties disliked by weevils.  Download the Factsheet

check Slugs

Try some simple steps to keep your garden free of both pesticide use and slug problems. Clear away weeds, stones, boards, and other shelter for slugs; handpick them off your plants as needed; and use slug traps and barriers when necessary.  Download the Factsheet

check Ticks

Worried about ticks? Never fear! There are several pesticide-free ways to prevent ticks from affecting you. Modify your landscape, wear clothes that fit tightly around your wrists, ankles, and waist, and don’t let your pets climb onto the furniture.   Download the Factsheet

check Voles

There are many ways to reduce vole populations, including heavy mulch, mowing, soil cultivation, wire fences, and mouse traps. It is important to remember that voles are an essential link in the food chain, however, and cause no real damage when at reasonable population levels.  Download the Factsheet

check Yellow Jackets

Although they are useful insects, yellow jackets can also be painful pests. You can solve your yellow jacket problems without pesticides by reducing attractive food or drink and trapping when necessary.  Download the Factsheet
