Although you will need to experiment to see what works best in your climate, in your soil, generally Radishes and Marigold will repel Squash Bugs, while Squash Vine Borers do not like to be near cloves, onion and garlic. Similarly, planting strong smelling herbs like Valerian, Angelica, Cilantro, Lemongrass and Sage may deter adult moths from laying eggs that hatch into Melon and Pickle Worms.

How to Grow Winter Squash

Some flying insects such as wasps, bees and yellowjackets are beneficial to the garden as pollinators and predators of caterpillars and house, manure and fruit flies, however if their sheer numbers threaten your outdoor enjoyment or work in the garden, or if their nests are located near entryways to the house, then a trap is appropriate to decrease their population.

First, cut the top of an empty 2 liter soda bottle at its "shoulder." Next, invert this "funnel" into the lower portion of the bottle and staple it to the sides in several places. Punch a small hole in opposite sides of the bottle's open end and "funnel" and insert a loop of twine, wire or a coat hanger. Fill the bottle 1/3 full with a sugar and protein mixture such as a little milk over some peanut butter or any ripe fruit. The insects will be attracted to the mixture, fly in and be unable to find their way out and will drown. I like to add a few drops of hot sauce or pepper to the elixir to make sure they get an upset stomach(foregut) in the meantime. Finally, hang in a tree a few feet away from where the insect activity is heaviest. Hanging multiple traps will increase your chances of quick success. Make sure to renew the attractant mixture every few days or after any heavy rains, dumping the spent insects onto the compost pile.

Like many creatures in the natural world, Rats have comparative physical abilities that make human athletes look totally undeveloped. These abilities must be taken into account by the homeowner or Pest Control professional to effectively get rid of rats and to keep them out of homes, schools and workplaces. For instance:

Rat Squeeze: Rats can wriggle through openings as small as 1/2" (1.3 cm) square.

Rat Tightwire Walking: Rats can saunter along horizontal wires easily while Roof Rats can even climb vertical wires.

Tunnel Rats: Rats can crawl up the inside of vertical pipes as small as 1.5" or 3.8 cm, in diameter.

Rats as Outdoor Plumbers: Rats can shimmy up the outside of vertical pipes up to 3" or 7.6 cm, in diameter.

Rats as Plumbers and Electricians: If plumbing pipes or electrical conduit are within 3" or 7.6 cm of a wall, rats can crawl up them, probably even wearing a tiny tool belt.

Rats and Basketball or Volleyball: The pesky rodents can jump 36" or 0.9 m from a flat surface.

Rat Yoginis: From a flat surface, rats can stretch to reach about 13" or 33 cm.

Rat Swimmers and Divers: Even though they may be the last ones off a sinking ship, rats are able to dive and swim underwater for as long as 30 seconds. In open water, they can swim as far as 1/2 mile or 0.8 km. They can use these remarkable aquatic abilities to swim upward through waste pipes and into toilets.

Rats at the Dentist: Equipped with front teeth that continue to grow throughout their lives, rats are gnawing machines, attacking a vast array of materials from wood, lead pipes and cinder block to aluminum, glass, and adobe bricks.
