Your firewood pile could be “bugged.” Many insects like to overwinter in wood. A wood pile is an ideal place for some insects to survive the winter. They don’t know that you intend to bring their winter home indoors during cold weather.

During colder weather, you can unknowingly bring in pests such as spiders, beetles and roaches when you bring in firewood. It’s best to bring in firewood only when you are ready to use it. Otherwise, those pests could become active and start crawling around inside your house. Many insects are potential problems indoors and there are usually control options once insects move into your home. However, preventing the insects from getting inside is the best approach.

If you store wood indoors for short periods of time, it is a good idea to clean the storage area after you have used the wood. Using a first-in, first-out guideline as much as possible will reduce chances of insect problems.

It’s best to keep your wood pile off the ground and away from the house. This will make it less inviting to insects and help the wood dry. It’s not difficult to keep the wood off the ground. The wood can be stacked on a base of wooden pallets, bricks or blocks, which will allow air movement under the wood. The wood can also be covered with a waterproof tarp or stored in a shed. Regardless of how it is stored, avoid spraying firewood with insecticides. When burned, insecticide treated wood may give off harmful fumes.

Some critters that live in firewood can be harmful to humans. To avoid a painful sting or bite from insects, spiders or scorpions (no Florida scorpion is considered poisonous, but they can inflict a painful sting), it is a good practice to wear gloves when picking up logs from a wood pile.

Firewood can be a good source of heat during our cold weather. If you’re careful with how you handle your firewood, hopefully it will warm you, not “bug” you.

The most numerous animals on the planet are insects and although less than 1% cause damage to our landscapes, most are viewed as pests.  Many insects perform clean up tasks that keep our environment from being littered with carcasses and trash while others actually attack and feed upon insects that are direct pests to plants.

It is important to recognize that all insects are not pests and take the time to get to know a few that might actually be performing a beneficial job in your landscape.   Probably the most easily recognized beneficial bug family in Florida landscapes are the ladybird beetles (Coccinellidae).  There are several species of ladybird beetles with different food preferences including mildews, mites, whiteflies, scale insects, and aphids.

Another group of insects that include some predatory species is the stink bugs.  Some stink bugs do eat plants, but there are also many that are beneficial such as Florida predatory stink bug (Euthyrhynchus floridanus).  The Florida predatory stink bug preys on velvetbean caterpillar, okra caterpillar, alfalfa weevil, and flatid planthopper.  One of the distinguishable characteristics between plant feeding and insect feeding stinkbugs are the shape of their shoulders.  Plant feeders have rounded shoulders and predatory have points on their shoulders.

The next time you are disturbed by a bug in your garden, take a moment to watch what it is eating and try to identify it before assuming it is a pest.  After all, there are many beneficial bugs that help to balance out the “bad bugs.”
