If your was built before 1978 and you have children under the age of seven, you will want to have an inspection for lead-based paint. It's important to know that lead flakes from paint can be present in both the home and in the soil surrounding the house. The problem can be fixed temporarily by repairing damaged paint surfaces or planting grass over effected soil. Hiring a lead abatement contractor to remove paint chips and seal damaged areas will fix the problem permanently.
If deer are hungry enough, they will eat almost any plant. However, some plants are less appealing than others, depending on what your local population has learned to eat so far. Daffodils are often cited as being deerproof, along with glory-of-the-snow (Chionodoxa) and crocus. Unfortunately, tulips and lilies are deer favorites. You might ask some of your neighbors if they have had luck with any particular plants, then try those in small quantities as an experiment. Many gardeners use repellent sprays with varying success, but to be as effective as possible they must be applied and reapplied according to the instructions. Home remedies include using soap, blood meal, human hair, and so on, but in the end the only truly reliable solution is a deer-proof fence.
