- Limit sun exposure to early morning or late afternoon
- Make sure you wear proper protection with a wide brim hat and sunglasses
- Always, always wear long-sleeved shirts, long pants, and socks
- Most dermatologists recommend all parts of the body that are not covered by clothes should be adequately protected with broad spectrum, water-resistant sunscreen of sun protection factor (SPF) 30 or higher every two hours while outside.

By now, most of you are familiar with cicadas. Every summer the chunky brown nymphs crawl from under the ground and perform a transformation as dramatic as the change of a chrysalis to a butterfly. Though the individual life cycle may last several years for the annuals, the entire population does not emerge in synchrony as do their famous earlier periodical cousins. You should now be able to enjoy their daytime buzzing and still hear yourself think.

Lightning bug adults produce a heat-free source of light through a biochemical reaction. The light flashes are used to attract mates. Different species have different flash patterns and are active at different times during the evening.
What does this have to do with pest management? One of the many great aspects of lightning bugs is that the larvae of some species are predatory on snails and slugs!

Remember, baits are effective only if they are eaten and not all baits are equally attractive to different ant species. Make sure the bait you use is acceptable to the ants. Place a small amount of bait where you see ants foraging and then watch their reaction for a few minutes. If the ants show no interest in the bait, try another bait until you find one that they readily feed on. Once you find a bait that is acceptable to the ants, several other factors determine its effectiveness, including:
* Sanitation - Baits work best when there are no other food sources available to ants. Keep areas clean so ants are not "distracted" from locating and feeding on the bait.
* Proper placement - Bait should be placed in known or suspected areas of ant activity. Be sure that bait is placed out of the reach of children, pets, and wildlife. Never place bait directly on countertops where food is prepared or in an area where it will get wet and/or contaminated.
* Quantity - Make sure you put out enough bait and that it remains fresh. If the ants carry away all of the bait, then they may leave the area and go elsewhere before enough bait is spread within the colony. Ant species that are capable of producing large colonies, such as the Argentine ant, will most likely require more than one application of bait.
* Durability - Baits will eventually become unacceptable if they are exposed to high temperatures, rain, and sunlight. Check baited areas for signs of ant feeding and replace baits that are no longer acceptable to the ants.
* Patience is important to successful baiting. Most ant baits are slow-acting. You may continue to see ants for a week or more after baiting. It is important that the ants are able to return to the nest with the bait so it can be fed to other members of the colony. Do not disturb or kill the foraging ants.
* Remember, if you determine that chemical control is needed to successfully control the ants, never spray in areas baits have been applied. If the baits are contaminated, the ants will avoid the bait.
